China Power Line Numbering Method

• Power cord numbering method:

 Insulated wires can be divided into single-stranded wires and multi-stranded wires according to the number of strands of each wire. Generally, insulated wires of more than 6mm2 are multi-stranded wires, and insulated wires of 6mm2 or less can be single-stranded wires. It can be a multi-strand line. We also call a single-stranded wire of 6 square millimeters and below as a hard wire, and a multi-stranded wire as a cord. Hard lines are denoted by "B" and cords are denoted by "R". The B series is categorized as cloth wire, so it starts with B.

• V is PVC PVC, which is (PVC plastic)

 L is the code of aluminum core

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

 The insulation materials commonly used for electric wires are polyvinyl chloride PVC and polyethylene PE. Polyvinyl chloride is represented by "V" and polyethylene by "Y".

 The number of mutually insulated conductors that are fixed together by insulated wires can be divided into single core wires and multiple core wires, and multiple core wires can also be fixed in one insulating sheath with multiple single core wires. Multiple cores in the same jacket can be up to 24 cores. The parallel multicore wire is indicated with "B", and the twisted multicore wire is indicated with "S".
