ten, cloth wire (voltage levels: 300/500V, 450 / 750V; Executive Standard: GB5023-1997) 
  insulated wire conductors per share can be divided into single strands and strands, usually more than 6 mm2 insulated wires are strands, 6 mm2 and below The insulated wire may be a single strand, it can be multi-strand line, we again 6 mm2 and below called hard wire strands, multi-strand wire cord is called. Hard lines "B" indicates the cord with "R" means. 
  B Series classified belong wire cloth, so beginning with B 
  V is PVC polyvinyl chloride, which is the (plastic) 
  L is the aluminum core code 
  R is (soft) means, to achieve soft, is to increase the number of conductor 
  wires used insulating materials are PVC and polyethylene are two polyvinyl chloride "V" represents polyethylene with "Y" means. 
  Insulated wires together at a fixed number of roots mutually insulated conductors can be divided into single-line and multi-core, multi-core cable can also put multiple single wire fixed on an insulated jacket. Within the same multi-core cable sheath may be more to the 24 core. The multi-core cable in parallel with "B", said multi-stranded wire with "S" means. 
  Understanding of the above, we can easily see that the meaning of wire models as follows: Model name 
  BV PVC insulated copper wire; 
  BVV Copper conductor PVC insulated wire; 
  BVR Copper core PVC Vinyl insulated cords; 
  RV PVC insulated copper cord; 
  RVB copper core PVC insulated flat cable cord; 
  BVS copper core PVC insulated twisted cord; 
  RVV Copper core PVC insulated poly PVC sheathed flexible cord; 
  BYR polyethylene insulated flexible wire; 
  BYVR PE insulated PVC sheathed flexible cord; 
  RY polyethylene insulated cords; 
  Ryv PE insulated PVC sheathed flexible cord
