- Commodity name: Copper-core halogen-free low-smoke insulation and sheath copper mesh shielded twisted pair WD(Z/ZC/ZB/ZA)-series RYYPS and RYJYPS
Cables for connecting and wiring applications in household appliances, small electric tools, instruments, electronic devices, automation systems, and power and lighting installations, with shielding requirements, rated at 300/300V or lower.
Use
Cables used for connecting and wiring appliances, small electric tools, instruments, electronic devices, automation equipment, and power and lighting systems with rated voltages of 300/300V or lower, where shielding is required.
Main features
Ambient temperature: 0℃ to 40℃ (for mobile installation); during short circuits (within 5 seconds), the maximum conductor temperature shall not exceed 70℃.
Bending radius: For cables with an outer diameter of 25 mm or less, the bending radius should be no less than 4 times the cable’s outer diameter; for cables with an outer diameter of 25 mm or more, the bending radius should be no less than 6 times the cable’s outer diameter.
Material requirements: The conductor shall be bare copper circular soft conductor conforming to GB/T 3956-2008/IEC 60228:2004. The insulation and sheath shall comply with the requirements of GB/T 32129-2015. The corresponding materials are listed in the table below.Model
