1. WDZ-YJ-Y is a type of cable.
2. The model of this cable consists of several parts: WD indicates chlorine-free low smoke, Z indicates flame-retardant, YJ indicates cross-linked polyvinyl chloride insulation, and Y indicates polyethylene sheath.
3. Therefore, WDZ-YJY cable refers to a flame-retardant copper core cross-linked polyvinyl chloride insulated polyethylene sheathed cable with chlorine-free low smoke characteristics.
4. The conductor of this cable allows a long-term operating temperature not exceeding 70 degrees Celsius.
5. During laying, the temperature of the cable should not be lower than 0 degrees Celsius.
6. The bending radius of the cable during laying should not be less than 10 times the outer diameter of the cable, and for cables with armor or copper tape shielding, this ratio should be 12 times. Additional information:
1. Polyvinyl chloride insulated and sheathed control cables are suitable for indoor, cable trench, pipeline, and underground environments.
2. Polyvinyl chloride insulated and sheathed copper braid shielded control cables are also suitable for the above environments and have anti-interference capabilities.
3. Polyvinyl chloride insulated and sheathed soft control cables are suitable for indoor environments where flexibility is required.
4. Polyvinyl chloride insulated, polyvinyl chloride sheathed copper braid shielded soft control cables are similar to the second type and also have anti-interference capabilities.
5. Polyvinyl chloride insulated, fine steel tape armor control wires are suitable for indoor, cable trench, pipeline, vertical well, and underground environments and can withstand greater mechanical forces.
6. Polyvinyl chloride insulated, thin steel wire armor polyvinyl chloride sheathed control cables are suitable for indoor, cable trench, pipeline, vertical well, and underground environments and can withstand some tension. Reference: Polyvinyl chloride insulated and sheathed control cables -百度百科.
