What does BVR wire mean BVR wire cable specification model
What does BVR wire mean? BVR is copper core PVC insulated flexible cord; The following is a detailed interpretation of THE BVR cable cable specifications, I hope to help you!
BVR wire is a kind of special flexible wire for distribution cabinet, also called secondary wire. Copper core PVC insulated flexible wire is used for fixed wiring where softness is required. By the majority of electricians and building decoration personnel like.
BVR wire
What does BVR mean
BV, BVV, BVVB, BVR Power Cord:
To put it simply: VV in wire terms means two layers of dew ethylene;
BV polydew ethylene insulated copper core wire, single core wire;
BVV, dew ethylene sheathed copper core wire, two core wire;
BVVB dew ethylene sheathed copper core, is a three-core wire;
BVR, copper conductor PVC insulated flexible wire, fixed wiring when required soft occasions.
People ask the usual wire on the market BV,BVR,RV,RVV, not those large section of engineering cables
The B series belongs to the distribution wire, so it starts with B, voltage: 300/500V;
V is PVC, polyvinyl chloride, which is plastic;
L is the code for the aluminum core;
R means soft, and to be soft, you increase the number of conductors;
BV copper conductor PVC insulated wire;
BLV aluminum core PVC insulated wire;
BVR copper conductor PVC insulated flexible wire.
Above wire structure: conductor + insulation.
Take 2.5mm2 for example:
There are two kinds of BV: 1 root with diameter of 1.78mm and 7 root with diameter of 0.68.
BLV is 1 root with diameter of 1.78mm; BVR is 19 root with diameter of 0.41mm.
RV copper conductor PVC insulated flexible wire it is softer than BVR, or 2.5 is 49 0.25mm copper wire;
The RVV copper conductor PVC insulated PVC sheathed flexible wire has one more layer of plastic sheathed than the RV
Also: Our most common "sheath line"
BVVB copper conductor PVC insulated PVC sheathed flat cable is 2 BV wire, in addition to a layer of white sheathed.
