As a Rubber Cable Manufacturer, let's talk about the difference between RVV and BV.
The insulated wires are divided into single core wires and multi-core wires according to the number of mutually insulated wires, and the multi-core wires can also fix the plurality of single core wires in one insulating sheath. The multi-core wire in the same jacket can be as many as 24 cores.
Parallel multi-core wires are indicated by "B", and twisted multi-core wires are indicated by "S". Insulated wires can be divided into single-strand and multi-strand wires according to the number of strands of each wire. Generally, insulated wires of 6 square millimeters or more are multi-strand wires, and insulated wires of 6 square millimeters or less can be single-strand wires. It can be a multi-strand line. We also refer to a single strand of 6 square millimeters and below as a hard line, and a multi-strand line called a cord. Hard lines are indicated by "B" and soft lines are indicated by "R".
Commonly used insulating materials for wires are polyvinyl chloride and polyethylene, polyvinyl chloride is represented by "V", and polyethylene is represented by "Y". With the above in mind, it is convenient to see the meaning of the wire model, as shown below.
