The difference between home improvement wire BVR line and BYJ line

In ordinary building decoration, the choice of home improvement wire, mostly copper hard wire, rarely used soft wire, hard wire and soft wire in addition to the installation of the difference between the pipe, there are some differences in product performance, here, the national network The cable gives you a simple understanding of the difference between the BVR line and the BYJ line of the home improvement cable.
BVR: copper core PVC insulated soft wire, B means cloth wire, R means soft
BYJ: Copper core XLPE insulation cloth wire
The performance of the two products is the same:
1. The composition of the two products is the same, consisting of two parts: conductor and insulation;
2, both belong to the decoration wire series, the voltage is 450/750V;
From the full name of the two products, it can be seen that the difference between the BYJ line and the BVR line is roughly analyzed, then the specific differences between the two products are as follows:
1. Although both belong to the wire type, one belongs to the copper hard wire and one belongs to the copper soft wire;
2. Although both are single-core wires, but the composition of the number of cores of the conductor is different, BYJ belongs to a core formed by a single hard copper conductor, and the BVR belongs to a core composed of a plurality of thin copper wires twisted together;
3. On the constituent materials of the product, the insulation materials of the two are different. BYJ uses XLPE insulation material, and BVR uses PVC insulation material;
4. The bending radius is different when the product is installed, the same outer diameter is 25mm, the bending radius of the BYJ line is 8D, and the bending radius of the BVR line is 6D;
5. The temperature resistance level of the two is different from the temperature at the short circuit: since the BYJ line is made of cross-linked polyethylene material, the temperature resistance level is 90 ° C, and the temperature at the time of short circuit can reach 250 ° C; and the BVR line is Polyvinyl chloride material, so the temperature resistance level is 70 ° C, the temperature at short circuit can reach 160 ° C;
6. Due to the difference in insulation materials between the two, if the fire is burned, the BYJ line releases less toxicity than the BVR line;
