What are WDZAN-BYJ and WDZA-BYJ wires?
1. WDZA-BYJ is a halogen-free, low-smoke, flame-retardant wire.
WD: Halogen-free, low-smoke. This designation means the toxic smoke produced by the insulation and protective layer materials when burned in flames is below the required level. It is used for power distribution in larger public spaces (such as large shopping malls).
Z: Flame retardant, B: Insulated wire, and YJ: Cross-linked polyethylene. Both are rated A for flame retardancy. BYJ: Cross-linked polyethylene insulated wire.
WDZA-BYJ is a low-smoke, halogen-free, non-toxic, and environmentally friendly wire. It is rated A for flame retardancy and is not fire-resistant (no N indicates it is not fire-resistant).
2. WDZAN: Flame-retardant, fire-resistant (N stands for fire-resistant). WDZAN-halogen-free, low-smoke, fire-resistant cables; WDZAN-BYJ/WDZBN-BYJ clean and environmentally friendly cables are suitable for 0.6/1kV and below power transmission and distribution systems, control lines, and various critical locations requiring flame retardancy, fire resistance, smoke-free operation, harmlessness, and high-temperature resistance. WDZAN-BYJ/WDZBN-BYJ clean and environmentally friendly cables can be widely used in crowded places and high-rise buildings such as power stations, power plants, steel mills, oil wells, machine rooms, schools, and entertainment venues.
What is the difference between WDZA-BYJR and BVR?
The difference between WDZA-BYJR and BVR lies in their insulation. The "WDZ" in the front of WDZA-BYJR refers to the insulation's low-smoke, zero-halogen properties (environmentally friendly; combustion or volatile gases contain no halogen). A denotes the grading of low-smoke, zero-halogen (WDZ) properties, which are divided into four grades: A, B, C, and D, with A being the best. BYJR and BVR differ in the middle letters, one YJ and the other V, referring to the different nature of the insulation materials. YJ stands for cross-linked polyethylene, while V stands for polyvinyl chloride. Cross-linked polyethylene (YJ) outperforms polyvinyl chloride (V) in all aspects (insulation performance, temperature resistance, etc.). The remaining letters, B, and R, refer to the soft core, and they are the same. This shows that WDZA-BYJR is essentially an environmentally friendly, upgraded version of ordinary soft cloth wire. This product is designed for power transmission and distribution lines with a rated voltage of 1 kV or less, where flame retardancy and fire protection are required, such as in high-rise buildings in the petroleum, chemical, power plant, subway, hospital, mine, airport, etc. It produces no toxic gases or smoke in the event of a fire.
WDZAN-BYJ, WDZA-BYJ, and WDZA-BYJR cables all share common characteristics. Customers should select the appropriate cable based on their installation method and specific requirements.
