Scope: This document specifies the terms and definitions, product classification, evaluation requirements, and evaluation methods for green products of electrical wires and cables with a rated voltage of 0.6/1kV and below. This document applies to electrical wires and cables with a rated voltage of 0.6/1kV and below. Halogen-containing products (such as those using raw materials such as polyvinyl chloride, chloroprene rubber, or halogen-free flame retardant polyolefins) are not within the scope of application of this document. Main technical content: 5.2.1 Product resource attribute indicators 5.2.1.1 The conductor shall be made of annealed copper conductors, or aluminum or aluminum alloy conductors. Among them, the copper conductors shall be made from copper billets of not less than T1 or TU1 grades. The conductor structure and DC resistance value shall comply with the standard requirements, and: a) For conductors with a physical measured cross-sectional area of not more than 1.0% of the nominal cross-sectional area at 630mm2 and below, and not more than 1.4% of the nominal cross-sectional area at 800mm2 and above; b) The standard requires that products with a conductor structure of Type 5 or Type 6 and other soft copper strands shall not use single wires with a maximum single wire diameter requirement (despite the increase in the number of single wires) that exceeds the lower value of the diameter of the conductor type and/or specification (nominal cross-sectional area). Example: For a 1.5mm2 Type 5 soft copper conductor, the single wire (nominal) diameter design value is 0.25mm. It is not allowed to select a Type 6 soft copper conductor with a (nominal) diameter of 0.15mm, nor a Type 5 soft copper conductor with a lower specification of 1.0mm2 and a (nominal) diameter of 0.20mm. 5.2.1.2 The average value of the insulation thickness shall not be less than the nominal value, and the deviation shall comply with the requirements of Table 1.
