BV wire is standard single rigid wire for building concealed wiring. High-purity solid copper cuts resistance, heat loss and energy waste during power transmission.
Thick uniform PVC insulation offers strong voltage resistance, anti-aging and anti-cracking performance. It effectively prevents leakage and short circuits inside wall conduits.
The stiff single core stays straight, making threading through wall slots and junction boxes simple. Multiple wire sizes cover lighting, socket and main circuits for all buildings.
It works steadily under regular indoor temperatures and requires little maintenance for long-term concealed use.
Product Advantages
Pure solid copper ensures stable conductivity and low power consumption.
Thick PVC insulation improves safety and avoids electric leakage risks.
Rigid single core greatly eases concealed pipeline threading work.
Full range of cross-sections matches various power load requirements.
Aging-resistant insulation extends service life for indoor laying.
Application Scenarios
Hidden wall wiring for apartments, villas and office spaces.
Circuit connection for distribution boxes, lamps and wall sockets.
Electrical construction in malls, schools and factory buildings.
Wiring for new home decoration and old circuit renovation projects.
