Brief introduction of wire and cable products

Electric wire divides into the electromagnetic wire and the general purpose insulated wire by the use. Insulated wire is also called cloth wire. Insulated wire (wiring wire) refers to the wire covered with an insulating layer, including all kinds of connecting wires and installation wires. Before we talk about the wiring specification, let's first understand the meaning of the letter in the wiring specification: B (B) -- the first letter means wiring, and the second letter means glass filament. V (V) -- the first letter stands for polyethylene (plastic) insulation and the second letter for polyethylene sheath. L (L) -- aluminum, no L means copper, F (F) -- compound, R -- flexible wire, S -- twisted pair, X -- insulating rubber

Cloth wire specifications notation: BVR - copper (aluminum conductor, PVC insulated, soft line, the voltage rating: 450/750 v, executive standard: bv JB8734.2-1998 - no sheath copper core PVC insulated wire and cable, voltage levels: 300/500 v, executive standard: the BLV JB8734.2-1998 - the aluminum conductor, PVC insulated sheathed wire and cable BVV - round copper core PVC insulated vinyl chloride sheathed wire, voltage levels: 450/750 v, executive standard: BLVV JB8734.2-1998: Aluminum conductor, PVC insulated PVC sheathed cable, voltage levels: 300/500 v, executive standard: JB8734.2-1998 BVVB: copper core PVC insulated PVC sheathed flat cable, voltage levels: 300/500 v, executive standard: JB8734.2-1998 such types of wire cloth is suitable for various ac and dc electrical devices, electrical and instrument, instrument, telecommunications equipment, power and lighting fixed installation with; RV -- copper core PVC insulated flexible wire, voltage grade: 300V
