DLO Cable Manufacturers

1X Technologies DLO Cable - Diesel Locomotive Cable 

What is a DLO cable?

DLO Cable stands for "Diesel locomotive cables". DLO Cable was originally developed for wiring diesel-electric locomotive trains dating back before the 1920's, over 100 years ago. Back then, these heavy duty 2KV Diesel Locomotive cables were used as power-leads in traction motors. The DLO Cables were were used as open wiring to the Diesel Electric motors where they were made to take a massive amount of wear and tear. In today's world,  DLO cables (Also called Type DEL Cable) are still used in wiring diesel-electric locomotives, but more commonly used in applications such as Submersible Pump cable, battery cable, Belden DLO Cable, control panel power distribution, VFD power feed and as motor leads, earth moving equipment, drilling rigs, marine shipboard cable, in open air or in conduit wherever durability and wear and tear are prevalent. DLO cables are (UL) listed as RHH/RHW-2 2kV and available in sizes 14 AWG through 1111 Kcmil, temperature rated 90 degree C. When DLO Cable is used as conductors for general wiring practices according to NEC Article 310 based on their RHW/RHW-2 listing the conductors cable class is subject to the requirements of NFPA 70 / NEC Article 310 the same as any other RHW insulated conductors. Contact us today at 1-888-651-9990 to get updated pricing on your DLO Cable, we'll quickly get you a DLO cable cost to price your job.

DLO cable ampacity / DLO cable amps / DLO cable current rating

DLO Cable Ampacity varies from 35 Amps up to 1115 Amps depending on which size you require. Diesal Locomotive Cable "Ampacity" is defined as the maximum current, in amperes, that a DLO Cable conductor can carry continuously under the conditions of use without exceeding its 90C temperature rating. This is also described as dlo cable current rating, its current-carrying capacity. The ampacity of a DLO conductor depends on its ability to dissipate heat without damage to the conductor or its EPDM Rubber insulation. DLO cable amps is a function of the insulation temperature rating, the electrical resistance of the conductor material, the ambient temperature, and the ability of the insulated conductor to dissipate heat.    

DLO Cable UL, NEC, CSA

1.1  UL 44 - This (UL) Standard specifies the requirements for single-conductor and multiple-conductor thermoset-insulated wires and cables rated 600 V, 1000 V, 2000 V, and 5000 V, for use in accordance with the rules of the Canadian Electrical Code, Part I, CSA C22.1, in Canada, Standard for Electrical Installations, NOM-001-SEDE, in Mexico, and the National Electrical Code (NEC), NFPA 70, in the United States of America. See Annex a for the complete list of types and voltage ratings covered by this Standard and the specific electrical codes for which they are intended, and Annex b for a summary of construction and test requirements for these types. 1.2 Table 1 provides a summary of the maximum conductor temperature, voltage ratings, and the number of insulated conductors for the types to which this Standard applies. 1.3 This Standard also specifies the requirements for submersible pump cables, with or without jackets, in Deep Well Submersible Water-Pump Cable, Section 7. No type-letter designations are assigned to these cables. 1.4 Products within this Standard might have applications not covered by the electrical codes listed in 1.1. UL:  (CPE jacket) RHW-2 90C wet and dry, VW-1, Sun Res, for 1/0 and larger ST-1, FT-4, IEEE1202, for CT use C(UL):  TYPE RW90 EP; 1000V; FT1 CSA:  RW-90 90C; FT1; FT4; -40C; for 1/0AWG and larger: OIL RES, Tray Cable, Sun Res  

Can DLO cable be used in conduit?

When used as General Wiring in accordance with the NEC, DLO Cable can be used in Conduit. DLO Cable is listed as UL 44 RHH-RHW-2 which is a building wire. When DLO Cable is used as conductors for general wiring practices according to NEC Article 310 based on their RHW/RHW-2 listing the conductors cable class is subject to the requirements of NFPA 70 / NEC Article 310 the same as any other RHW insulated conductors, and therefore just as any other RHW insulated conductors such as XLP-USE building wire, may be used in conduit. DLO cable conduit fill may be calculated using any of the accessible calculators commonly found online.  

DLO Cable Bending Radius

During electrical installation, DLO cables are bent or flexed in various environmental conditions. Diesel Locomotive Cables are often bent around a curve in conduits or underground ducts. Cables are also bent when pulling a DLO electrical cable around a sheave, which is a pulley set up in a manhole to help ease a cable around a curve. Type DEL Cables (DLO) are composed of different components that may become compromised if bent too far and stress is placed on the electrical cable. To prevent cable damage, cable standards such as The National Electrical Code (NEC) and the Insulated Cable Engineers Association (ICEA) formed requirements for minimum bend radius. DLO Cable Bending radius: For fixed installation – minimum 4 x O.D., for flexible or temporary installation – minimum 6 x O.D. Diameter of the cable.    

DLO Cable Cost  - Price Per Foot

Diesel Locomotive Cable costs more than your typical general building wire due to its construction being composed of extremely durable components. Being a super flexible stranded tinned copper 2KV cable with an extra durable EPDM insulation and CPE jacket makes for a really amazing cable, but it can be pricey if you are comparing to standard THHN or XHHW. Pricing can range from $.25 cents per foot for 14 AWG to upwards of $40.00 per foot for 1111 MCM DLO Cable. Pricing depends on how many feet are ordered, where it is shipping, what copper base is at time of order and a variety of other factors.
