350 MCM 1C Type W Portable Power Cable, 2000V

350 MCM 1-Conductor Type W Portable Power Cable is an extra-flexible 2000V heavy industrial cable engineered for temporary power distribution, mobile equipment, and generator leads. Built with 3416-strand bare copper, EPR insulation, and a heavy-duty CPE jacket, it resists severe abrasion, oil, and extreme cold down to -40°C. Dual-rated as Type RHH/RHW-2 (600V) under UL 44, it can smoothly transition from temporary jobsite leads to permanent cable tray and raceway installations.

Key Features & Benefits

• Extreme Flexibility & High-Strand Copper: Built with 3416 fine strands of bare copper (ASTM B3), offering effortless bendability that resists metal fatigue, kink damage, and strand cracking under continuous dragging, reeling, and tight jobsite turns.

• Ultra-Rugged Thermoset CPE Jacket: Heavy-duty, pressure-extruded Chlorinated Polyethylene (CPE) outer sheath delivers maximum resistance to severe mechanical impact, crushing, tire run-overs, sharp rock abrasion, oil, grease, and aggressive chemicals.

• Extreme Weather & UV Protection (-40°C to +90°C): Engineered to be highly ozone, sunlight (UV), weather, and flame resistant while enduring light water immersion. It remains 100% pliable in sub-zero cold down to -40°C while delivering full 90°C wet/dry thermal protection under direct sun.

• 2000V Industrial Heavy-Duty Power Rating: Engineered with high-dielectric Ethylene-Propylene Rubber (EPR) insulation to deliver 2000V power density, handling heavy current loads without thermal breakdown or electrical leakage.

• Dual-Rated Compliance (Type W / RHH/RHW-2): Operates as a 2000V portable trailing cable under UL 1650 / NEC Article 400 AND as a 600V permanent RHH/RHW-2 building wire under UL 44, allowing for direct installation in permanent cable trays and conduit.

• Internal Reinforcement Tape: Features a single-faced rubber-filled binder tape applied over the insulation core to lock the jacket in place and prevent sleeve slippage under high drag tension.
