T/SOECC 005-8-2022 Aluminum copper-clad round wire for insulated copper-clad aluminum conductors Part 8: Straight-weld 155-grade insulated aluminum copper-clad round wire for enamelled copper-clad aluminum round wire

Scope

Main Technical Content: Copper-Aluminum Round Enameled Wire Part 8: 155 Grade Direct Welding Polyurethane Enameled Copper-Aluminum Round Wire 1 Scope This part specifies the requirements for 155-grade direct welding polyurethane enameled copper-aluminum round wire. If the original resin's chemical properties can be preserved and all the requirements of this enameled wire are met, the resin can be modified. Note: A modified resin is one that has undergone chemical changes or contains one or more additives to improve its performance or usage characteristics. The 155-grade indicates the thermal rating, which requires a minimum temperature index of 155 and a thermal shock temperature of at least 175°C. The Celsius temperature corresponding to the temperature index is not the recommended operating temperature of the enameled wire, as this depends on many factors, including the type of equipment used. The nominal diameter range of the conductor specified in this part is: — Grade 1: 0.071 mm and above, 0.800 mm and below; — Grade 2: 0.071 mm and above, 0.800 mm and below. The nominal diameter of the conductor is in accordance with the provisions of Chapter 4 of Part 1. 2 Normative Reference Documents The provisions of the following documents are incorporated into this part by reference from T/SOECC. For dated reference documents, all subsequent amendment sheets (excluding errata) or revised editions are not applicable to this part. However, parties reaching agreements based on this part are encouraged to investigate whether the latest versions of these documents can be used. For undated reference documents, the latest versions apply to this part.
