- Commodity name: Copper-core halogen-free low-smoke insulation wires WD(Z/ZC/ZB/ZA)-series BY and BYJ
For power connection of household appliances, small electric tools, instruments and meters, as well as power and lighting installations with rated voltages of 450/750V and below.
Use
Used for connecting power supplies to household appliances, small electric tools, instruments and meters, as well as power and lighting installations with rated voltages of 450/750V and below.
Main features
Ambient temperature: The fixed installation temperature shall not be lower than 0℃.
Bending radius: When the cable outer diameter (D) is less than or equal to 16 mm, the bending radius should be no less than 4D; when the diameter exceeds 16 mm, the bending radius should be no less than 6D.
Material requirements: The conductor shall be annealed copper wire (bare copper) without any metal plating, conforming to GB/T 3956-2008/IEC 60228:2004. The insulation shall meet the requirements of GB/T 32129-2015. The corresponding materials are listed in the table below.Model
