6 AWG Diesel Locomotive Cable, 2000V

6 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 6 AWG DLO cable cut by the foot with zero cut fees, saving you material waste and jobsite prep time.

DISCLAIMER: The technical information provided is for general reference only. Industrial high-voltage power networks and flexible cable trays must strictly comply with the National Electrical Code (NEC), local municipal safety enforcement mandates, and individual equipment installation datasheets. Always verify official product submittal listings and exact core metrics with your electrical component manufacturer prior to configuring terminal arrays or subjecting lines to high pulling forces.

• Locomotive Controls & Power Sub-Systems: High-flex 105A power leads routing electricity to auxiliary blower motors, lighting arrays, diagnostic consoles, and control sub-systems from locomotive generators.
• Solar & BESS Inverter Wiring: Interconnects commercial solar combiner boxes, string inverters, and Battery Energy Storage Systems (BESS) where heavy-duty 2000V insulation and tight bending radii are required.
• Industrial Motor Control Centers (MCC): High-flexibility panel wire and cross-connect jumper lines within crowded industrial switchgear cabinets where standard building wire is too rigid to route.
• Oil & Gas Rig Power & Control Skids: Deployed across onshore and offshore drilling platforms to safely supply power to localized telemetry sensors, control skids, and automated valves exposed to harsh vibration.
• Data Center UPS & Battery Bank Jumpers: High-flexibility battery connections and control links within high-density uninterruptible power supply (UPS) rooms and telecommunications networks.
• Marine Vessel & Shipboard Sub-Systems: Internal shipboard power distribution, bilge pump control, and radar tower wiring with superior resistance to salt spray, moisture, and chemical corrosion.
• Mining Machinery Controls & Articulations: Auxiliary power feeds for electric shovels, draglines, and continuous miners operating under severe mechanical vibration and dynamic movement.
