1/0 Diesel Locomotive Cable, 2000V

1/0 Diesel Locomotive Cable (DLO) is an extra-flexible 2000V single-conductor industrial power cable engineered for heavy feeder runs, main generator leads, and high-vibration industrial power distribution. 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 and Tray Cable rated (TC) for 1/0 AWG and larger, this cable handles dynamic equipment movement while remaining fully code-compliant for permanent cable tray and raceway installations.

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 pulling through complex tray networks and conduits.

• 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.

• Tray Cable (TC) & Dual-Rated Compliance: Certified as 2kV DLO for flexible machinery leads, dual-rated as 600V/2000V RHH/RHW-2 under UL 44, and rated for Cable Tray (CT) use in sizes 1/0 AWG and larger.

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

• Custom Cut-to-Length: Wire America supplies 1/0 AWG DLO cable cut by the foot with zero cut fees, saving you material waste and jobsite prep time.

TECHNICAL & CODE COMPLIANCE NOTICE: Product specifications, outer dimensions, stranding layouts, and weight figures are nominal manufacturer estimates based on industry standards and are subject to normal manufacturing tolerances. Ampacity ratings are derived from National Electrical Code (NEC®) Table 310.17 for single conductors in free air at 30°C ambient and 90°C continuous conductor operation. Final cable selection, conduit fill sizing, and installation methods must be verified by a qualified engineer or licensed electrician in accordance with local building regulations and the latest NEC standar
