• 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
