Diesel locomotive cable, also known as DLO cable, is a flexible portable power cable designed for use in diesel-electric locomotive engines. However, it is also suitable for use in heavy-duty power applications and motor leads where ruggedness and reliability are critical. Our DLO cable features a stranded tinned copper conductor, EPR insulation, and a CPE jacket. It has a maximum temperature rating of +90°C and a voltage rating of 2000V. Our DLO cable also has UL Type RHH/RHW-2, CSA Type RW90, and MSHA approval.

Our DLO Cable has tremendous resistance to impacts and abrasion, and can also resist sunlight, alkalies, oil, heat, and fire. The thermoset insulation provides excellent flexibility and abrasion resistance. The flexible stranded tinned copper conductor also improves this cable's length of life. We carry diesel locomotive cable from 14 AWG to 020.2 MCM. Since DLO Cable is used for many applications besides diesel-electric locomotives, it is often compared to Welding Cable.
