Cable RHH RHW-2 is copper conductors that are made from high-quality, annealed (soft-drawn) bare copper with Class B stranding under ASTM standards. Each conductor is insulated with tough, cross-linked polyethylene (XLPE), engineered to resist abrasion, moisture, heat, flame, and sunlight. This construction ensures long-lasting performance across a wide range of demanding environments.
Application
RHH RHW-2 Cable is designed for multiple code-compliant applications, these cables can be used in conduit, raceways, or as direct-burial underground service entrance (USE-2) conductors. The cable is rated for 600 volts and supports operating temperatures up to 90°C in both wet and dry locations. It is suitable for a wide range of residential, commercial, and industrial projects.

Feature

RHH cable and RHW-2 cable are very similar in structure. Both use annealed (soft) copper conductors and use cross-linked polyethylene (XLPE) insulation, which has excellent heat resistance, moisture resistance, abrasion resistance and UV resistance. However, RHH cable is mainly designed for dry environments and is not suitable for long-term use in wet or underground environments. RHW-2 cable is suitable for dry and wet environments, and can be used for underground direct burial installation. It is more common in building exteriors or outdoor power distribution systems. Its waterproof performance is better than RHH.
Certification
RHH cable and RHW-2 cable have successfully obtained UL certification. The RHH cable certification number is UL-US-2561148-0, and the RHW-2 cable certification number is UL-US-2561143-0. The certification can be verified in the UL official database, with clear traceability. Customers can be confident that the products they install meet all applicable NEC (National Electrical Code) requirements and can also get reliable safety, service life, and compliance in demanding electrical systems.
