Now the development of science and technology is too rapid, so in the electrician industry on the wire requirements are also more and more high, and there are many wires are required for special use, which is the most representative of the wire is bvr wire. bvr wire is a distribution box in the special use of wire, also known as the secondary line, the bvr inside the material is a copper core, the outer packaging is polyethylene material, so in the wiring time Very convenient, so the line is particularly popular with electricians. I guess there should be a lot of friends on the bvr line is not very familiar with, then let me say to you about the bvr line.
bvr wire
BVR wire is a kind of distribution cabinet special soft wire, also called secondary wire. The use of copper-core polyvinyl chloride insulated soft wire, its application in the fixed wiring requirements of soft occasions. By the majority of electricians and building decorators like.
Difference between BV and BVR:
(1) From the production process, BV is single-core, BVR is multi-core, in the production, BVR is a little more complex than BV.
(2) from the price, BV and BVR because of its only in the process, BVR is a little more expensive than BV. In the International Electrotechnical Commission on the provisions of the range of BVR is from 2.5?mm?to?70?mm However, according to the actual needs of our country, is the same as BV.
(3) in performance, BV and BVR is basically the same, the weight of the BVR slightly heavier;
Likewise, the BVR wire according to the choice of different materials, but also divided into flame-retardant wires (ZR-BVR), fire-resistant wires (NH-BVR), low smoke halogen-free wires (WDZ-RYJ). Users according to the use of the occasion flexibility. One of the low-smoke halogen-free (low) halogen wire in the flame combustion situation produces a very small amount of smoke, the release of gas does not contain halogen (low-halogen) elements, non-toxic (low toxicity). When the fire occurs, can greatly reduce the apparatus, equipment and human hazards, and therefore is widely used in high-rise buildings, hospitals, large libraries, gymnasiums, disaster prevention command and scheduling building, stations and civilian airports, passenger waiting rooms, key cultural relics protection sites and subways, underground shopping malls or densely populated public **** place.
What are the specifications of bvr wire
BVR1 square, BVR1.5 square, BVR2.5 square, BVR4 square to BVR185 square are in stock
BVR wire, BVR wire, copper wire, copper wire is also known as the special line for power distribution cabinet, the secondary line, the commonly used models are BVR1 square, BVR1.5 square, BVR2.5 square, BVR4 square to BVR185 square have stock
BVR wire, BVR wire, copper wire, also called distribution cabinet special line, secondary line, common models have BVR1 square, BVR1.5 square, BVR2.5 square, BVR4 square, BVR6 square and so on. This article describes in detail the specifications of the various models of BVR parameters, current-carrying capacity, as well as wire diameter, weight.
Bvr wire is a very important wire in our life, and is mainly used in the distribution box, wiring time to use. Because bvr wire has a very good flexibility, and inside the copper core material conductivity is very good, and the outside is polyethylene material covered, so bvr wire in the use of not only convenient, but also the safety performance is very high. And bvr wire is non-toxic, environmental performance is also very good, so most friends will choose to use bvr wire. The above article we share on bvr wire is also very detailed, I hope you can better understand the class of wire.
