BVR Soft Copper Wire

Introduction

BVR:Copper core PVC insulated soft sheathed wire

Voltage: 300/500 v

the wire structure: conductor + insulation

Conductor is copper wire, the average diameter of each wire is less than one millimeter.

the commonly used PVC insulated wires are: BV, BLV, BVR
 

BV, BVV, BVR power cord

in simple terms: v v in the wire term refers to the meaning of two layers of PVC;

                               BV PVC insulated copper core wire, single core wire;

                               BVV, PVC sheathed copper core wire, two core wire;

                               BVR, copper core PVC insulated flexible wire.

the letter "B" stands for wiring (for example: make indoor power line, nailed it on the wall),the letter " V" - polyvinyl chloride (PVC) plastic sheath (a V represents an insulating layer two V double insulation), namely plastic insulation. L represents aluminum wire, and without L represents copper wire. Letter R on behalf of the soft line, is to increase the number of conductors, reducing the diameter of each line.

BV is a single-core copper wire, hard and inconvenient construction, but strong; BVR for multi-core copper wire, soft, easy construction, but the intensity is small. BV single-core copper wire is generally used in a more fixed place; BVR multi-core copper wire is generally used for a slight movement of the occasion. In addition, BVR multi-strand current carrying capacity than a single strand, the price is also higher. Usually inside the cabinet can be used BVR, do not have such a large intensity, easy wiring.
