T/SOECC 005-2-2022 Nickel-coated aluminum round wire for motor windings - Part 2: Polyester-painted nickel-coated aluminum round wire of Class 130L

Scope

Main Technical Content: Copper-Aluminum Round Enameled Wire for Winding, Part 2: 130L-Class Polyester Enameled Copper-Aluminum Round Wire 1 Scope This part specifies the requirements for 130L-class polyester-based single-layer enameled copper-aluminum round wire. If the original resin’s chemical properties can be preserved and all the requirements for 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. 130L-class indicates the thermal rating, requiring a minimum temperature index of 130 and a thermal shock temperature of at least 155°C. Note: The thermal shock performance of the 130L-class enameled copper round wire specified in this part is lower than that of the 130-class enameled copper round wire specified in IEC 60317-45. The Celsius temperature corresponding to the temperature index does not represent 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: — Class 1: 0.071 mm and above, 3.150 mm and below; — Class 2: 0.071 mm and above, 5.000 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 through T/SOECC. For dated reference documents, all subsequent amendment sheets (excluding corrections) 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. T/SOECC 005.1-2022: Enameled Round Wire for Winding, Part 1: General Requirements 3 Definitions, Test Methods Gene
