Analysis of the Differences between WDZ - BYJ Wire and BV Wire

In t.owt he power systems of modern buildings, a type of wire named WDZ - BYJ is gradually becoming the mainstream choice. What exactly is it? And what are the differences between it and the common BV wire? Today, we will deeply analyze the differences between the two.

I.gni Product Definition and Model Meaning

1. WDZ - BYJ WireEach letter in WDZ - BYJ has a specific meaning. "WD" stands for halogen - free and low - smoke, indicating that this wire will not release toxic halogen gases when burning and has an extremely low smoke density. "Z" represents flame - retardant. "B" refers to a building wire, and "YJ" represents cross - linked polyolefin insulation. Its full name is copper - core cross - linked polyolefin insulated low - smoke halogen - free flame - retardant building wire, with a rated voltage of 450/750V, mainly used for fixed wiring.
2. BV CableThe BV cable is a type of wire widely used in daily life and industrial fields. Its full name is copper - core polyvinyl chloride insulated wire, simply called plastic - copper wire, and it is one of the most commonly used types of wires and cables.

II. Differences between the Two

1. Functional DifferencesThe WDZ - BYJ wire has the characteristics of being non - toxic, flame - retardant, long - lasting, and heat - resistant. It uses an irradiation cross - linking process to achieve flame - retardant effects, has a service life of about 70 years, and can withstand a high temperature of 105 degrees Celsius. While the BV wire, as a copper - core polyvinyl chloride insulated wire, has a maximum operating temperature of 70 degrees Celsius.
2. Different Insulation MaterialsThe BV wire uses copper - core polyvinyl chloride as the insulation material, while the WDZ - BYJ wire is a copper - core cross - linked polyolefin insulated wire. The insulation layers of the two are different. The insulation layer of the BV wire is polyvinyl chloride, and the insulation layer of the BYJ wire is low - smoke halogen - free flame - retardant cross - linked polyolefin.
3. Performance DifferencesIn terms of fire - proof performance, the WDZ - BYJ wire is superior to the BV wire. In terms of toxicity, the WDZ - BYJ wire is lower than the BV wire. The WDZ - BYJ wire is made of rubber materials that do not contain environmental harmful substances such as halogens, lead, cadmium, chromium, and mercury. When burning, it will not produce a large amount of harmful gases, only a small amount of white smoke, and will not cause secondary harm, belonging to an environmentally friendly wire.
4. Different Scope of ApplicationThe WDZ - BYJ wire is suitable for places with a rated voltage of 450/750V and below and higher requirements for safety and environmental protection, such as subways, airports, hospitals, large libraries, gymnasiums, hotels, schools, shopping malls, etc. The BV wire is mainly used for power supply, lighting, sockets, air conditioners, etc., and is suitable for cable wires used in power devices, household appliances, instruments, and telecommunications equipment with an alternating voltage of 450/750V and below. In addition, the BV hard wire has a certain hardness, which is more convenient for corner - folding and straightening operations.
5. Price DifferenceDue to the advantages of the WDZ - BYJ wire in materials and performance, its price is usually higher than that of the BV wire.

There are obvious differences between the WDZ - BYJ wire and the BV wire in terms of function, insulation material, performance, scope of application, and price. When choosing wires, it should be comprehensively considered according to the specific usage scenarios and requirements. For places with high requirements for safety and environmental protection, the WDZ - BYJ wire is a better choice. While in some ordinary places where the requirements for fire prevention and environmental protection are not so strict, the BV wire can meet the basic usage needs.

FAQ
