Scope

Scope: This standard specifies the terms and definitions, product models, flame retardant levels and markings, general requirements, testing methods, delivery length, inspection rules, packaging, transportation, and storage for double-insulated flame-retardant acid-resistant cables with a rated voltage of 450/750V and below. This standard applies to plating equipment, charging devices, and welding machines used for connection in environments with a rated voltage of 450/750V and below. Main technical contents: 1. Usage characteristics: Under normal use, the maximum temperature of the conductor is 70℃. The laying temperature of the cable should not be lower than 0℃. When the use range of the cable exceeds the above-mentioned limits, it can be resolved through consultation between the buyer and the manufacturer. 2. Insulation extrusion: The insulation extruded on the conductor should be a PVC/H type polyvinyl chloride mixture. 3. Sheath: 1. The sheath extruded on the insulated core should be a PVC/HJ type polyvinyl chloride mixture. 2. The maximum variation rate of tensile strength: ±35%; 3. The minimum value of elongation at break: 100% etc.
