12 AWG Diesel Locomotive Cable, 2000V

12 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 12 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.

Common 12 AWG DLO 2000V Applications

• Locomotive Control & Signal Wiring: Functions as highly flexible control wiring inside diesel-electric locomotive cabs, electronic switchboards, and braking control systems where high-density packing is required.
• High-Vibration Control Panels: Deployed as panel wire within industrial motor control centers (MCC), pump control panels, and automation enclosures subject to continuous structural vibration.
• Oil & Gas Rig Instrumentation: Used on onshore and offshore drilling rigs to route 2000V control signals, telemetry, and monitoring equipment in tight routing configurations.
• Marine & Shipboard Auxiliaries: Utilized for internal shipboard distribution, bilge control wiring, and lighting systems due to its extreme resilience against salt spray and moisture.
• Renewable Energy Inverter Controls: Connects monitoring arrays, tracking systems, and power circuits inside wind turbine nacelles and commercial solar collection panels.
• Heavy Machinery Electronic Feeds: Supplies flexible power and feedback signals to moving parts on industrial cranes, mining equipment, and robotic manufacturing cells.

Who Relies on 12 AWG DLO 2000V?

• Railroad & Mass Transit Systems: Relied upon by transit authorities, locomotive assembly plants, and rail maintenance yards for auxiliary signaling and dashboard wiring.
