? PVC insulation: ZA-BVR environmentally friendly flame retardant
? At present, the home is widely used for BV and BVR (single, 7 and 19). The main difference is that BVR is a multi-copper core. BV is a single copper core.
? BV------The letter V stands for PVC polyvinyl chloride, which is a plastic insulation layer.
? R ------ The letter R stands for soft meaning. To be soft, increase the number of conductors and reduce the diameter of each line.
? BV ------General purpose single core hard conductor unsheathed cable,
? BVR------Polyvinyl chloride insulated multi-strand copper core flexible wire. (For example: the conductor count of 2.5m2 is 19)
? RV-------- Specially thin conductors are stranded.
? PE insulation: WDZ-BYJ(F) Irradiation low-smoke halogen-free, NH-BVR fire-resistant wire
? WD------ Halogen-free low smoke flame retardant wire and cable
? Z ---------Flame retardant wire and cable
? BYJ ----- Cross-linked polyethylene wire and cable
? N -------- Fire resistant wire and cable
? F -------- Irradiated wire and cable
