Insulated wires can be divided into single strands and multiple strands according to the number of strands of each wire. Generally, insulated wires with a width of 6 mm 2 or more are stranded wires. The insulated wires of 6 mm 2 and below can be single strands, Can be multiple strands, we again 6 mm2 and below the single line called the hard line, multi-strand line called the cord. The hard wire is indicated by "B" and the flexible wire is indicated by "R". The company is located in:

　　B series belongs to the cloth wire, so the beginning with B

　　V is PVC PVC, which is (plastic)

　　L is the aluminum code

　　R is the meaning of (soft), to be soft, is to increase the number of conductors

　　Wire commonly used insulation materials are two kinds of PVC and polyethylene, PVC with "V" that polyethylene "Y" said. The company is located in:

　　Insulated wire according to the number of mutually insulated wires fixed together, can be divided into single-core and multi-core wire, multi-core wire can also be more than one single core fixed in an insulating jacket. Multiple cores in the same jacket can be up to 24 cores. Parallel multi-core wire with "B" said, twisted multi-core wire with "S" said. The company is located in:

　　Understand the above, you can easily see the meaning of wire models, as follows: Model Name

　　BV copper core PVC insulated wire;

　　BVV copper core PVC insulated PVC sheathed wire;

　　BVR copper core PVC insulated cord;

　　RV copper core PVC insulation installation cord;

　　RVB copper core PVC insulated flat cable cords;

　　BVS copper core PVC insulated twisted cords;

　　RVV copper core PVC insulated PVC sheathed cord;

　　BYR polyethylene insulated flexible wire;

　　BYVR polyethylene insulated PVC sheathed cord;

　　RY polyethylene insulated cord;

　　RYV polyethylene insulated PVC sheathed cord
