T/SOECC 005-3-2022 Enamel-insulated copper-clad aluminum round wire - Part 3: 155-grade polyester-insulated copper-clad aluminum round wire

Scope

Main Technical Content: Copper-Clad Aluminum Round Wire for Enameled Coils Part 3: 155 Grade Polyester Enameled Copper-Clad Aluminum Round Wire 1 Scope This part specifies the requirements for 155-grade polyester-based single-layer enameled copper-clad 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 enhance 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 does not necessarily 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 to 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.
