Scope

Main technical content: 7.2 Conductors The conductors shall consist of one or more pure metal or metal alloy wires. If the conductors are composed of pure copper wires coated with a metal layer, the metal coating shall match the operating temperature of the conductors. The resistance of the conductors at (20 ± 1) °C shall comply with the company's process requirements, with a maximum deviation of +10% to 5%. 7.3 Insulation The insulation uses fluoroplastic, with a minimum average thickness of 0.3 mm, and the thinnest point shall not be less than 0.20 mm. The performance of the insulation material shall comply with the requirements of Table 1. 7.4 Shielding layer 7.4.1 The resistance shall comply with the requirements of GB/T 20841. 7.4.2 The penetration resistance of the shielding shall comply with the requirements of GB/T 20841.
