PV RHW-2 Cable Construction
| Conductor | Single copper conductor |
| Insulation | chemically crosslinked polyethylene |
| Voltage | 1,000/2,000 Volt |
PV RHW-2 Cable Application
- Service Entrance Conductor: Introduces power from the utility transformer to the building’s main distribution panel.
- Feeder Circuit: Distributes high-power loads within industrial plants, data centers, or large commercial buildings.
- Underground Feeder (when installed in conduits): Extends from pad-mounted transformers to buildings.
- High-bay lighting and industrial machinery.
- As part of large cable assemblies (e.g., MC-type cables containing multiple RHW-2 conductors).
PV RHW-2 Cable Standard
- ASTM Standards: B-3 (soft or annealed), B-8 (concentric lay stranded), B-787 (combination strand)
- UL 44 RHW-2, UL 854 USE-2, and UL 4703 PV Wire
- C(UL) RPVU90 1kV/2kV: CSA C22.2 #271
PV RHW-2 Cable Feature
- Maximum Humidity Temperature Rating: 90°C humidity rating is its core safety advantage.
- Robust Physical Protection: The combination of cross-linked polyethylene and thickened PVC sheathing provides exceptional resistance to physical damage.
- Environmental Adaptability: Features moisture resistance, chemical corrosion resistance, UV resistance, and flame retardancy.
- Code Compliance: Meets the most common and stringent cable tray installation codes.
- Current-carrying advantage: The 90°C rating provides valuable “headroom” for derating calculations.
