T/SOECC 005-9-2022 Painted copper-clad aluminum round wire for round wire windings - Part 9: 180-grade direct-weld polyurethane-painted copper-clad aluminum round wire

Scope

Main Technical Content: Copper-Clad Aluminum Round Enameled Wire, Part 9: 180-Grade Direct Welding Polyurethane Enameled Copper-Clad Aluminum Round Wire 1 Scope This part specifies the requirements for a single enamel layer based on polyurethane resin for 180-grade direct welding copper-clad aluminum round wire. If the original resin's chemical properties can be preserved and all the requirements specified 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 enhance its performance or usage characteristics. The "180 grade" indicates the thermal class, 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 this enameled wire, as it depends on many factors, including the type of equipment used. The nominal diameter range of the conductor specified in this part is: — Grade 1: 0.090 mm and above, 1.000 mm and below; — Grade 2: 0.090 mm and above, 1.000 mm and below. The nominal diameter of the conductor is in accordance with the provisions of Chapter 4.2 of Part 1. 2 Normative Reference Documents The provisions of the following documents are referenced in this part by T/SOECC and become part of this document. For dated reference documents, all subsequent amendment sheets (excluding errata) or revised versions 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 version applies to this part.
