Diesel Locomotive (DLO) Cable

DLO Cable Construction

Conductors	Fully annealed flexible strand Class I tinned copper
Separator	All sizes except for 14AWG have tape separator between conductor and insulation
Insulation	Ethylene-Propylene Rubber (EPR)
Jacket	Black heavy duty thermoset CPE. Ozone, sunlight, oil, grease, weather, chemical, and abrasion resistant

DLO Cable Application

Rail & Transportation: Main power cabling for diesel-electric locomotives, subway trains, and transit vehicles.
Industrial Equipment: Heavy-duty mobile machinery (such as electric shovels and drilling rigs), mining equipment, and shipyard power supply cables.
Renewable Energy: Down-tower power cables within wind turbine towers and connections for energy storage batteries.
General Power: Motor lead wires, generator connection cables, battery bank cables, and welding equipment leads.

DLO Cable Technical Data

Voltage Rating: 2000 volts
Temperature: -40°C to +80°C

DLO Cable Feature

High Abrasion Resistance: Capable of withstanding repeated friction against rough surfaces—such as cable trays, metal edges, and rocks—without easily sustaining damage.
Tensile and Compressive Strength: Although DLO cables typically do not bear longitudinal tensile loads, their robust jackets and compact construction enable them to withstand a certain degree of tension and compression during installation, preventing core displacement or jacket tearing.
Low-Temperature Impact Resistance: Retains its flexibility even in environments as cold as -40°C without becoming brittle or cracking, making it suitable for outdoor installation in cold regions or for use in cold storage facilities.
