About DLO Cable

We offer all different sizes of Diesel locomotive cable (DLO Cable) listed below including #8#1#4#2#6 etc. We can supply you with the MCM sizes as well including 373, 444, 777, 535 etc. It’s a 2000 Volt 90°C power cable used for locomotive leads and motor leads.

WesBell stocks many different types of power cableWelding Cable is a very flexible, 600 Volt, 90°C power cable with a rubber EPDM jacket. SOOW is a flexible, multiconductor power cable, and our entertainment cable is 600 Volt, 105°C Type SC power cable used for portable power systems in the entertainment industry.

DLO Cable Acronym

DLO stands for Diesel Locomotive because DLO cables are used to power locomotives. Immediately you imagine a large cable for such an application and you’re absolutely correct. DLO cable has two layers of insulation to protection it in severe conditions and so that it can hold a UL approved 2000 volt rating.

There are many similar cables on the market but, ultimately, they don’t compare at all. Welding cable, entertainment cable, stage lighting cable and UL approved welding cable are all still inferior to DLO cable. For instance, all of the cables listed are rated for 600 volts and none of them compare to the diesel insulation layers that can protect the copper from dump trucks running over it on rocky construction sites.

DLO cable is UL, CSA, MSHA and RoHS approved for use in severe environmental conditions. You can find locomotive cables in gauge sizes 10 through 777 MCM which all use 24 gauge copper strands for flexibility. The rubber insulation layers are also designed with flexibility in mind so that DLO cables can be convenient and portable.

If DLO cable sounds a little too diesel for your application you should view our welding cable which is better suited for garages and shops with low voltage equipment. Welding cable is similar but with a single layer of rubber insulation and a 600 volt rating.

4 Layers of DLO Cable

1. Copper Strands

DLO stands for Diesel Locomotive cable and the thin copper strands help with the cables flexibility. DLO cable uses 24 AWG strands in all sizes from 14 AWG to 1111 MCM. Each AWG increase uses more strands until it reaches the necessary diameter of the gauge in question. DLO cable is much more flexible than typical electrical wire or building wire but slightly less flexible than welding cable and stage lighting cable.

2. Tinned Coating

Most portable cord has bare copper strands which makes DLO cable unique in this area. There is a tinned coating over each strand in diesel locomotive cable to help adhere to the adhesive when connecting lugs. The adhesive is placed on the copper strands before applying the lug which helps the connection from the lug to the adhesive to the tinned copper strands.

3. EPR Rubber Insulation

The EPR rubber insulation is the first layer of insulation used on DLO cable. Since it’s used outdoors to connect power to diesel locomotives and telecom supply it needs to have plenty of protection. The jacket needs to be strong and durable because it takes quite a bit of daily abuse in its application.

4. CPE Rubber Insulation

Remember, “portable” power cables are stepped on, run over, dragged along the ground and constantly caught in tight areas that could puncture the insulation and expose the copper strands. Therefore, a second layer of CPE rubber insulation is applied to DLO cables for a double layer of protection. The voltage rating is also 2000 volts which is higher than one-layer-portable-cables at 600 volts.
