Home wiring is an indispensable part of our life, and the quality of pvc wire selection will be directly related to home safety. Home safety is your own safety, so you must compare more when you buy, choose the wire with guaranteed quality. So what specifications should the general home wiring choose? What about the BVR copper wire for home decoration? Now I will make a simple analysis for you.
General home decoration line specifications
The power cord for home decoration generally adopts BV2 × 2.5 and bvv2 × 1.5 model of BVV line, BVV line is the national standard code, copper sheath line bvv2 × 2.5 and bvv2 × 1.5 represents 2-core 2.5 square mm and 2-core 1.5 square mm respectively. In general, bvv2 × 2.5 main line, bvv2 × 1.5 make single electrical branch line, switch line, share bvv2 for air conditioning special line × 4 model, with special ground wire.
We all know that BVV wires are commonly used in household wires, and there is another kind of BVR wires. How much do you know about BVR wires?
BVR copper core flexible wire for home decoration
BVR wire is a kind of special soft wire for distribution cabinet, also called secondary wire. The full name is PVC insulated non sheathed wire and cable, the model specification and rated voltage are BVR 450 / 750V 2.5-95, and the production execution standard is JB / T 8734.2-2012.
The copper core PVC insulated flexible wire is used in the occasions where the fixed wiring requires softness, and the conductor temperature is 70 ℃ in normal use.
The number of bvr6 square wires, wire diameter of 19 / 0.64mm and outer diameter of 5.2mm. The conductor material of the product is made of 99.99% oxygen free copper. The copper wire has bright appearance and low resistivity, which improves its conductivity.
The only difference between BVR wire and bv wire is that the conductor diameter of R wire is soft copper wire. That is: increase the number of conductors, reduce the diameter of a single conductor, the diameter of a single conductor is less than 1 mm. In this way, the BVR wire is very soft, the laying angle requirements are greatly reduced compared with BV wire, and it is more convenient and fast when threading the conduit and trunking, which reduces the work intensity and greatly improves the work efficiency. Very popular with the majority of electrical and architectural decoration personnel welcome!
BVR wire can be divided into flame retardant wire, fire-resistant wire and low smoke halogen-free wire according to different materials, which can be flexibly controlled by users. Low smoke and halogen-free produce a very small amount of smoke in the case of flame combustion, the released gas does not contain low halogen elements, non-toxic. In case of fire, it can greatly reduce the harm to instruments, equipment and human body.
It is not difficult to see that BVR wire has many advantages, but it does not absolutely match the needs of any place. Or have to combine their own needs to buy, of course, good brand is also the key! So I hope the above can bring some help to the friends who are facing the problem of choosing household wires.
