T/GDWCA 0006-2018 Hot-melt insulation hot-melt sheath extruded cable

Scope

Scope: This standard specifies the terms and definitions, product models, product names, and product presentation methods, usage characteristics, general requirements for cable structure, finished cable testing, delivery length, inspection rules, marking, packaging, transportation, and storage of thermoset insulated and thermoset sheathed extruded cables. This standard applies to thermoset insulated and thermoset sheathed extruded cables with AC rated voltages of 30V, 60V, 90V, 125V, 150V, 300V, and 600V. Main technical content: I. Usage characteristics: 1. The long-term operating temperature of the cable model used shall not exceed the rated temperature of the product. 2. The rated voltage of the product shall be the value specified in the product specifications, etc. II. General requirements for cable structure: 1. When the insulation contacting the copper conductor is tested for corrosion of the unprotected copper and no protective isolation layer is used, each single wire of the solid conductor and the stranded conductor shall be covered with a suitable metal or alloy plating. 2. The plating on the stranded conductor is only necessary to prevent the insulation layer from adhering to the copper conductor and not for corrosion prevention. In this case, the plating is only allowed on the outermost metal wire. 3. The insulation shall be tightly wrapped around the conductor core and shall be easy to peel off without damaging the insulation layer and plating, etc.
