Protecting Your Expensive Hoses, Wiring and Cabling: Rubber Grommets

When you’ve spent a packet on expensive wiring and cabling at home, factory or your office, you don’t want it to be damaged by repeated flexing or friction, exposure to the elements and contamination by dirt and dust. Hoses, tubes and pipes can be vulnerable to similar damage, leading to safety issues as well. If you have delicate lacings or cords as accessories for your blinds and curtains, these can fray and become worn out.

A simple and inexpensive solution is to install rubber grommets at the appropriate points where stretching, bending or repeated friction occur. Another point where grommets can be fixed is where the wire, welding cable or cord emerges from a punched hole in plastic or metal sheets and tends to rub against a sharp edge.

Grommets are available in both rubber and plastic and in a variety of shapes and sizes, and you can choose depending on your needs.

In this article, we will discuss the specifics of rubber grommets.

Rubber grommets are essential in the automotive, medical, agricultural and industrial sectors. They are also used in engine fittings battery cable and in the defense establishment.

Manufactured from highly durable molded rubber or SBR (Styrene Butadiene Rubber) with similar tensile and elastic qualities as automobile tires, these grommets are designed to withstand tearing, abrasion, weather-related ageing and damage from exposure to petroleum products. Most of the standard products can also tolerate extreme temperatures, ranging from 107C to -50C. The tensile range is also extensive: between 30-100 psi. Depending on your requirement, some manufacturers may also offer additional compounds in the SBR, such as silicone, Neoprene etc.

Rubber grommets come in a standard round shape and are very easy to install and can simply be snapped into the hole. They have great adhesion properties and the only point to keep in mind is that you must choose the grommet of the exact dimension and panel size to fit the hole or exit point where it must be installed. Rubber grommets generally come in a black finish.

Several manufacturers also offer customized units in different shapes like oval, horse-shoe, or flat. They may also supply grommets with multiple holes or plug solar cable and blind types depending on your exact specifications. You can also avail of the free catalogs and samples offered by retailers to assist you in making your choice.

Rubber grommets are easily available in most hardware stores and do not require great technical expertise to install. In case you are shopping online for them, you may have to place bulk orders. You must also ensure that they are properly packed and dispatched.

Rubber grommets will provide long-lasting and efficient protection to your expensive cables, electric wire and hoses.

If you are looking for plastic machining as well as plastic prototypes, Get the latest innovative technology of plastic products and pipe cap and moulding services. We pride ourselves on having a range of first class plastic products like threaded tube.

Cable Insulators

A basic plastic material which can be made in many forms. The Wiring Regulations now refer to PVC as a “thermoplastic” material, meaning that its form can be changed if its temperature exceeds a certain level. It is robust, chemically inert, has good aging and fire-resisting properties. It is more resistant to weathering and sunlight than rubber, but will harden and crack in the presence of oil or grease. High temperatures lead to softening and possible insulation failure, whereas at low temperature, PVC may become brittle. Very little absorption of water will occur, although PVC is inferior to polychloroprene in this marine electrical cable. PVC is widely in use as a sheathing material as well as for insulation. It can only usually be used where conductor temperature does not exceed 70.C. The material emits dense smoke and corrosive fumes when it burns.

Vulcanised rubber (VR) (thermosetting)

A good electrical insulator with high flexibility. The Wiring Regulations now refer to VR as a “thermosetting”material, meaning that its form cannot be changed after manufacture. It is subject to rapid aging and cracking due to weathering and exposure to sunlight, and softens and becomes sticky in the presence of oils and greases.

It ages rapidly at high or low temperatures. It is not widely used but is available in a form which will operate safely up to 85.C.

Polychloroprene (PCP) (thermoplastic)

Polychloroprene, also known as Neoprene, is a plastic material of lower strength and lower insulation resistance than PVC. However, it is more resistant than PVC to weathering, and to attack by oils, acids, solvents, alkalis and water. PCPis more elastic than PVC, and this elasticity is not affected by increased temperatures. Although more expensive than PVC, PCP is used as a marine shipboard cable insulation and sheathing material for conditions where PVC would not be suitable.

Silicone rubber (thermosetting)

Silicone rubber is a synthetic material with many of the advantages of natural rubber. It has good weathering properties, and will resist attack from water and mineral oils, but not from petrol. It remains elastic over extremes of temperature (.70.C to 150.C).

https://youtu.be/yVPMXtgUWF8

Butyl rubber (thermosetting)

Butyl rubber is another synthetic material which is less expensive than silicone rubber but has similar advantages. It remains flexible over the range.40.C to 85.C, but will burn readily once ignited. Ethylene.

Propylene rubber (EPR) (thermosetting).

EP rubber is generally similar to butyl rubber, but with improved properties. It is resistant to heat, water, oil and sunlight, and is suitable for direct burial, exposure to weather and contaminated atmospheres. It is used to insulate solar power cables which have an increased current rating owing to its heat resistance.

Chlorosulphonated polyethylene (CSP) (thermoplastic)

This material is mainly used for sheathing cables insulated with other plastics. It is capable of operating over the temperature range.30.C to 85.C, and has excellent oil resisting and flame-retarding properties. It is very tough, and very resistant to heat and water. This is the sheathing material which is called “HOFR”(heat resisting, oil resisting and flame retarding) in the IEE Wiring Regulations.

Magnesium oxide

This material is in the form of a white powder, and is invariably used in mineralinsulated cables. It also finds application in some heating elements. Magnesium oxide is non-aging and will not burn, but it is very hygroscopic (absorbs moisture from the air), when it loses its insulating properties. It is unaffected by high temperatures, and is a good conductor of heat.

Cross-linked polyethylene (XLPE) (thermoplastic)

This is a polymeric insulation (like EPR above) and is used particularly for 4 AWG gauge battery cable. In this application it shows cost advantages over oil-filled and pressurized cable insulation, not least in the simpler jointing techniques which may be used. The material does not burn easily, and when it does, only limited emission of smoke and fumes occurs.

Paper Dry or oil-impregnated paper, wound in long strips over the conductors, was the most common method of insulating underground cables but has now been overtaken by XLPE. As long as the paper is kept dry (usually by sheathing with lead alloy) its insulating properties are excellent.

Glass fibre

Glass fibre, impregnated with high-temperature varnish, is used to insulate some flexible cords used for high-temperature lighting applications.

Baitron is specialized in sourcing hard-to-find components and ICs through its unparalleled worldwide network of supply.

How a cable itself affects the audio signal

Now, going back to the ways that the unarmored cable itself can change the signal going through it, let’s consider both types of cables separately.

As stated previously, interconnect cables carry a very small amount of current. Relative to the current the voltage is large. Because of that fact, capacitance is important, but inductance is relatively unimportant. As the voltage oscillates between being positive and negative, the capacitance slows the voltage changes down, and causes delays. This can cause audible distortion in the sound. Because interconnects have very little current, resistance is not much of a factor. Even an interconnect with extremely high resistance will only remove an infinitesimally small amount of energy.

The signal in loudspeaker cables is essentially the opposite of the signal in interconnects. Both cables have the same information, but in loudspeaker armored cable sizes, the voltage is small and the current is large, relatively speaking. Because of the high current, both resistance and inductance are important in loudspeaker cables. The higher the resistance, the greater the amount of energy that will be absorbed by the cables. The resistance will not cause any distortion, but it will decrease the volume of the sound. The inductance on the other hand, can cause distortion. As the current oscillates between being positive and negative, the inductance slows the current changes down, and causes delays.

https://youtu.be/yVPMXtgUWF8

How a cable lets outside sources of energy affect the signal

As stated previously, the second fundamental way of altering a signal passing through an audio cable is to introduce outside sources of energy. This outside energy is typically termed “noise”. By definition, if any energy is absorbed by the signal, the signal has been distorted.

There are many potential sources of noise around audio cables. Some of the more common sources of noise, such as radio frequency waves, are familiar to most people. When wiring up a radio, frequently a consumer must attach an antenna. Antennae are intentionally designed to channel radio frequency energy into a stereo. Just like an antenna, it is entirely possible for an audio cable to pick up radio frequency energy. If you are not intending to listen to the radio, this is not a welcome effect.

Electronic components, electrical cords, sound waves, and even the sun, are all capable of creating noise. Electrical cords create electromagnetic fields around them that can transfer energy to a solar panel wire. Sound waves create mechanical vibrations that can be transformed into electrical energy that is added to an audio signal. Because there are so many different types of noise, there are many methods used to prevent a cable from picking up noise. Shielding, twisting of conductors, and mechanical damping are all common noise protection methods in cables.

While noise affects both interconnects and loudspeaker cables, generally the effects are far more significant in interconnects. This is because the signals in the interconnects have far less energy. Since most forms of noise are inherently low energy to begin with, this means that it is far easier for them to modify the low energy interconnect signals than the high-energy loudspeaker cable signals.

Macro vs. Micro

The parameters discussed so far have been primarily “macro” effects. These are for the most part the top-level parameters that effect cables. These parameters as well as others not discussed here also exist at a “micro” level. Taking capacitance as an example, a given cable will have an overall capacitance that can be measured. This overall capacitance is a “macro” level parameter. The same cable can also be analyzed as 1000 separate but connected pieces. Each piece will have a local capacitance. These local parameters are “micro” effects and can have their own impact on the signal separate from the “macro” effects.

The impact that the “micro” level parameters have on an audio signal is usually less than the impact of the “macro” level parameters. However, they do still make a difference in the signal transfer. The various ways that audio companies choose to either mitigate or ignore these “micro” level details is, in part, responsible for the vast array of different cat 5 cable designs. From cryogenic treatments and precious metal wires, to fine silk insulation and fluid filled cable jackets; extreme cable designs abound.

Will I hear the difference?

The fact of the matter is that cables do alter the sound going through them, and that it is audible. You do not need to be an expert, or an audiophile, to hear the difference. To demonstrate this point, simply listen to your stereo. If you close your eyes, does it sound like the music is being played live right in front of you? This is what audiophiles strive for, and unless you have a very high-fidelity system, your answer to this question will most likely be no. You may have a hard time describing what exactly does not sound right about your system, but you know that it doesn’t sound like a live performance.

Of course, the reason why the music does not sound live cannot be blamed solely on the cables. The degradation of the sound occurs in every component of your system. However, the point here is that even a casual listener can detect the subtle distortions that can prevent music playback from sounding live. Improving the quality of your audio cables will improve the sound quality of your system.

It is fairly safe to say that no matter what cable you use, the modifications to the sound will be small. Audio cables will never cause a listener to hear a piano when a flute is being played. However, it is the small detail that makes all the difference between good and bad quality sound. That is why very strong opinions are formed about various cables.

As audio systems continue to improve in accuracy, listening to a “live” performance in your living room gets closer to reality. Cables are an enabling factor for advancements in audio reproduction and can play a remarkably important role in your system.

Is 500 MCM Welding Cable The Biggest Gauge Size?

Yes welding cable is manufactured in gauge sizes that range from 6 AWG to 500 MCM. Manufacturers might make something larger but it would have to be engineered and there would be a very large minimum order of at least 10,000 feet. Otherwise, in order to get a electric wire you will have to use a similar type of single conductor electrical cable.

USE-2 solar panel cable is very similar but with additional benefits. It will cost slightly more but there are more approvals and it can be used as an underground cable without the use of conduit. USE-2 cable is also UL, CSA and MSHA approved while standard welding cable is not. Solar panel cable has a standard size of 1000 MCM which is the largest size of standard electrical cable in general. Even THHN wire which is completely different than welding cable only reaches 1000 MCM in size.

One of the main specifications users look for in welding cable is the flexibility. It has thin copper strands manufactured for flexibility and a rubber EPDM jacket that is also engineered to be flexible. Solar wire is made with tinned copper strands that aren’t quite as flexible because welding cable is used on a daily basis and it’s beneficial to have a cable that can work its way around corners without a problem. It also gets coiled and uncoiled often similar to an extension cord used by home owners.

The options start to get slim as you’re looking for a cable this large because it’s not often that someone needs to constantly use a 1000 MCM cable in order to make one that’s flexible. Normally installations with an electrical cable of that size will have it in conduit, underground or running from the telephone pole to your homes electrical box. A 500 MCM copper cable weighs 2 pounds per foot or 200 pounds for 100 feet.

In cases where an application needs more power than a 500 MCM welding cable can handle an electrician would switch to a multi conductor control cable such as Type W portable power cord. Type W has similar flexibility and insulation with multiple wires inside the same jacket.

You will have to speak to an electrician about the calculation but it might be the best avenue for someone to take that needs more power. You wire and cable supplier can help make sure you have a cable with the environmental protection needed for the application it will be in.

WesBell Electronics is a distributor of welding cable, portable cord, electrical wire and hook up wire. Please let us know if you have any questions about your 500 MCM Welding Cable or any other type of wire and cable you’re installing. We offer Free Shipping on orders over $250 on our website and we cut most of our cables to any length you need.

Shut off valve and Ball valve manufacturers from Vatacvalves.com

The benefits of water main valve exercise usually won’t be realized until a water main leak or break occurs, but then they will be significant. The fact that the process was carried out at all means that the people in charge know where all the valves in the system are located, which is the first benefit. Your Floating Ball Valve management program will also help you to find the location of the leak quickly, which means figuring out which valves to shut off and finding those valves is a speedy process. Any delay in the shutdown of valves in an emergency can mean severe damage to the system and chaos and injury above ground.

The emergency valve is the easiest and quickest way to cut off the water supply in the event of a serious leak. If you have your own well, you will normally find the emergency shut off valve by the pressure tank. If your water comes from your local town or city, you will normally find the emergency valve at the water supply meter. Inside the meter, you will find the emergency valve. You should be able to see the valve handle. There are other valves located under sinks and by the toilet. They will have a lever that you turn to shut off the water supply to that fixture. If you have a dish washer and washing machine, you will also find valves. As well, you can find a valve on the wall next to the water heater or in the basement. A valve handle can be a lever or look like a wagon wheel (Trunnion Ball Valve). You may need a wrench to close a valve.
