T/SOECC 005-5-2022 Enamel-insulated copper-clad aluminum round wire for motor windings - Part 5: 180-grade straight-weld polyester-imide-enamelled copper-clad aluminum round wire

Scope

Main Technical Content: Copper-Aluminum Round Coil Winding Wire Part 5: 180-Grade Direct Welding Polyester Imide Copper-Aluminum Round Wire 1 Scope This part specifies the requirements for a single-layer coating of polyester imide resin for 180-grade direct welding copper-aluminum round wire. If the chemical properties of the original resin can be preserved and all the requirements of this coated 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 "180 grade" indicates the thermal rating, which requires a minimum temperature index of 180 and a thermal shock temperature of at least 200°C. The Celsius temperature corresponding to the temperature index is not the recommended operating temperature for the coated 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, up to 1.600 mm; — Grade 2: 0.071 mm and above, up to 1.600 mm. The nominal diameter of the conductor is specified in accordance with Chapter 4 of Part 1. 2 Normative Reference Documents The provisions of the following documents are incorporated into this part by reference through T/SOECC. For dated reference documents, all subsequent amendment sheets (excluding errata) or revised editions are not applicable to this part. However, parties agreeing to 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.
