BVR wire knowledge points, how much do you know?

Published by Author: Joey Wan August 01,2022

BVR wire is a commonly used wire and cable. Today, I will briefly introduce BVR wire for you:

BVR wire is a kind of special soft wire for power distribution cabinet, and it is also used for secondary wire. It is used in applications where flexibility is required when fixing wiring. The maximum temperature of the conductor in normal use is 70°C. It is suitable for fixed installation of power units with AC rated voltage of 450/750V and below.

It can be used for home decoration lighting, and fixed wiring can be used for indoor exposure, pipe penetration, etc. In order to facilitate the difference in the installation process, there are seven colors: red, yellow, blue, green, black, white, and double. Since BVR is a soft structure, its application range is mostly in soft environment.

The difference between BV and BVR:

(1) In terms of production process, BV is single-core and BVR is multi-core. In production, BVR is a bit more complicated than BV.

(2) In terms of price, BV and BVR are a little more expensive than BV because they are only in the process. According to the International Electrotechnical Commission, the range of BVR is from 2.5 mm to 70 mm, but according to the actual needs of our country, it is the same as BV.

(3) In terms of performance, BV is basically the same as BVR, and BVR is slightly heavier in weight;

Letter meaning:

B refers to the classification belonging to the cloth wire, which is represented by the letter B.

V refers to PVC polyvinyl chloride, also commonly known as "plastic".

R means soft, to be soft, it is necessary to increase the number of conductors.

BV PVC insulated copper-copper core cable, single-layer skin copper-core cable;

BVV, PVC sheathed copper-copper cable, two-layer copper-core cable;

BVVB PVC sheathed copper copper core cable, double skin parallel copper core cable;

BVR, copper core polyethylene insulation layer flexible cable, specify a soft place when fixed and fixed.

 

The classification of B series products belongs to the distribution of cables, so B began to be used, the working voltage is 300/500V, and V represents PVC plastic polyethylene.
