Low energy loss, suitable for long-term power transmission.
Stable insulation
Good electrical insulation, aging resistance, and long service life.
Easy installation
Rigid conductor holds shape well for conduit and trunking installation.
Color identification
Different colors for phase, neutral, and earth wires for safe wiring.
Cost-effective
Reliable performance with a reasonable price, widely used in construction.
ZRBV Applications
- Residential building wiring: Household lighting, sockets, air conditioners, and kitchen circuits.
- Commercial & public buildings: Offices, schools, hospitals, shopping malls.
- Fixed power distribution: Indoor conduit, trunking, wall-embedded wiring.
- Light industrial power: Fixed wiring for low-power equipment and distribution boxes.
- Fire-safety related circuits: Emergency lighting, evacuation indication circuits.
