Live construction or home improvement will use wire and cable, commonly used wire BVJ single-core hard wire and BVR single-core flexible wire, that BYJ is what wire Ni? What is the difference with BVJ and BVR wires?

Here is what is BYJ wire:

First, the insulation layer of BYJ is polyethylene, then what is polyethylene? Crosslinked polyethylene insulated wire is a new type of building wire. This product occupies a large proportion in the construction market of Western countries, and is one of the most ideal construction lines in the world. The performance of the crosslinked polyethylene insulated wire should meet the requirements of GB5023-1997, B12706-1991, JB-8734-1998 standards. With the improvement of the requirements of many architectural design units for building lines in China, especially after joining the WTO, according to the principle of market access, the intensity of China's economic construction will be further increased, the scale of the construction market will be further expanded, and the relevant building codes will be more and more stringent. Government departments have begun to recommend the use of BYJ wires in public buildings. In this environment, some products with green, environmental protection and other new concepts have been favored, and crosslinked polyethylene wire is going to the market under this premise.

Wires commonly used insulation materials are polyvinyl chloride and polyethylene two, polyvinyl chloride with "V", polyethylene with "Y", BYJ product use: This product is suitable for rated voltage 450/750V and below buildings, electrical appliances, switches and other power equipment fixed wiring.

Second, what is the difference between BYJ and BVR products? How is it different from other wire models?

According to the above model analysis, BYJ and BVR are wires, suitable for construction and home improvement, the difference is that the insulation skin of BVR and BYJ is not the same, and the skin of BYJ is environmentally friendly relative to the price is more expensive: Other types of wire insulation materials are not the same, there are also differences in structure, and it is recommended that you should confirm the model specifications with electricians when purchasing.

Benefits of BYJ products:

1, with excellent mechanical and physical properties, good resistance to environmental stress cracking, excellent wear resistance, more than PVC and PE can withstand concentrated mechanical stress.

2, resistant to various chemical solvents, relatively stable in various corrosive media around.

3, the outer diameter of the cross-linked polyethylene insulated wire is smaller than that of the full PVC insulated wire of the same specification section.

4, in order to reduce the use of pipe diameter, or in the same pipe diameter conditions through more wires, reduce the cost of construction installation.

5, the weight of crosslinked polyethylene insulated wire products is much lighter than that of polyvinyl chloride insulated wire products, which is easier to install and transport.

6, labor intensity, reduce transportation costs.

7. The rated temperature of the crosslinked polyethylene insulated wire can reach 90℃ when working for a long time, and the short circuit (the longest duration is not more than 5S).

8, the higher temperature of the wire conductor can reach 250℃, and the carrying capacity is greater than that of the polyvinyl chloride insulated wire.

9, combustion does not release corrosive gases and toxic gases, will not produce secondary hazards, in line with modern fire safety requirements is a new type of environmental protection products.

10, good electrical performance, insulation resistance is much higher than PVC wire (cable), and the medium loss Angle tangent value tanδ is very small, basically does not change with the temperature.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
