XLP/USE-2/RHH/RHW-2 WIRE

XLP/USE-2/RHH/RHW-2 wire is a versatile, 600-volt rated electrical wire with a tough cross-linked polyethylene (XLP) insulation, designed for various applications, including direct burial, service entrances, feeders, and branch circuits. Its multiple ratings (XLP, USE-2, RHH, RHW-2) allow it to be used in a wide range of permanent installations in wet, dry, and damp locations, such as underground, in conduit, aerial, or in raceways. Available in both copper and aluminum conductors.

Copper and Aluminum XLP/USE-2/RHH/RHW-2 Wire

XLP-insulated wire with a triple rating of USE-2, RHH, and RHW-2 is a high-performance conductor engineered for the most demanding electrical environments. The "USE-2" designation identifies it as an Underground Service Entrance cable specifically rated for direct burial, while the "RHH/RHW-2" ratings certify it for use as a high-heat and moisture-resistant building wire in both wet and dry locations at 90°C. Featuring a rugged Cross-Linked Polyethylene (XLPE/XLP) insulation, this wire provides superior mechanical protection and chemical resistance without the need for an additional jacket. Available in both high-conductivity copper and cost-effective 8000-series aluminum, it is the premier solution for seamless power distribution from underground utility sources directly into commercial or industrial structures.

Key Features
  • Triple-Rated Versatility: Certified as USE-2, RHH, and RHW-2, allowing a single conductor to be used for direct burial, in-conduit, and indoor aerial applications.
  • Rugged XLPE Insulation: The cross-linked polyethylene jacket offers exceptional resistance to abrasion, crushing, moisture, and environmental stress cracking.
  • Direct Burial Rated: Specifically engineered for installation directly in the earth (USE-2) without the requirement for protective conduit.
  • 90°C Wet/Dry Rating: Maintains full ampacity and electrical integrity in temperatures up to 90°C in both saturated and arid environments.
  • Chemical & Oil Resistance: Highly durable against soil acids, gasoline, and industrial chemicals, ensuring a long service life in harsh locations.
  • Material Options: Offered in stranded soft-drawn copper for maximum flexibility or 8000-series aluminum for lightweight, large-scale feeders.
  • Industry Compliance: Manufactured to meet UL 44 (RHH/RHW-2) and UL 854 (USE-2) standards, fully compliant with NEC requirements.
Common Applications
  • Underground Service Entrances: The primary choice for routing power from a utility transformer directly to a building's main service panel.
  • Direct Burial Feeders: Used for running power to remote structures, pumps, and outdoor equipment without the cost of conduit.
  • Industrial Facility Wiring: Ideal for high-heat manufacturing environments where heavy-duty mechanical protection is required.
  • Solar Array Wiring: Frequently utilized in large-scale photovoltaic systems for both DC and AC power runs due to its UV and moisture resistance.
  • Wastewater Treatment Plants: Deployed in environments with constant moisture and chemical exposure for reliable motor and control power.
  • Battery Storage Systems: Used as a heavy-duty feeder for connecting large-scale battery banks to power inverters.
