10 AWG Diesel Locomotive Cable, 2000V

10 AWG Diesel Locomotive Cable (DLO) is an extra-flexible 2000V single-conductor industrial power wire engineered for high-density control panels, equipment leads, and harsh industrial environments. Constructed with finely stranded tinned copper, heavy-duty EPR insulation, and a pressure-extruded Chlorinated Polyethylene (CPE) jacket, it delivers maximum flexibility, vibration resistance, and chemical protection. 

Dual-rated as Type RHH/RHW-2 (600V and 2000V) under UL 44, this cable easily handles dynamic equipment movement while remaining fully code-compliant for permanent installations in conduits and control raceways.

Key Features & Benefits

• Corrosion-Resistant Tinned Copper: Built with high-strand tinned annealed copper (ASTM B-33/B-172) to prevent conductor oxidation, ensure long-lasting terminations, and provide superior flexibility for tight routing inside control enclosures.

• Premium EPR Insulation: Thermoset Ethylene Propylene Rubber (EPR) insulation delivers excellent dielectric strength, handling continuous 2000V electrical loads without thermal breakdown, cracking, or softening.

• Ultra-Rugged CPE Outer Jacket: Heavy-duty Black Chlorinated Polyethylene (CPE) thermosetting compound provides extreme resistance to oil, grease, petrochemical solvents, ozone, weather, and continuous UV exposure.

• Dual-Rated Compliance (DLO / RHH/RHW-2): Certified as 2kV DLO for flexible machinery leads AND dual-rated as 600V/2000V RHH/RHW-2 under UL 44 for permanent raceway installations.

• Sub-Zero Cold Flexibility: Rated for -40°C low-temperature flexibility, preventing jacket cracking or stiffening during dynamic payouts.

• Custom Cut-to-Length: Wire America supplies 10 AWG DLO cable cut by the foot with zero cut fees, saving you material waste and jobsite prep time.
