T/SOECC 005-12-2022 Painted copper-clad aluminum round wire for insulated round conductors - Part 12: 180-level self-adhesive direct-weld polyester-epoxy copper-clad aluminum round wire

Scope

Main technical content: Enameled Copper-Aluminum Round Wire for Winding, Part 12: 180-grade Self-adhesive Direct Welding Polyester Imines Enameled Copper-Aluminum Round Wire 1 Scope This part specifies the requirements for 180-grade self-adhesive direct welding enameled copper-aluminum round wire with a double enamel layer. The inner enamel layer is based on polyester imine resin. If the chemical properties of the original resin can be maintained and all the requirements of this enameled wire are met, the resin can be modified. The outer enamel layer is a self-adhesive layer based on thermoplastic resin. Note: A modified resin is a resin that has undergone chemical changes or contains one or more additives to improve its performance or usage characteristics. The "180 grade" indicates the thermal grade, which requires a minimum temperature index of 180 and a heat shock temperature of at least 200°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: - Class 1B: 0.071 mm and above, up to 1.600 mm; - Class 2B: 0.071 mm and above, up to 1.600 mm. The nominal diameter of the conductor is in accordance with the provisions of Chapter 4.2 of Part 1. 2 Normative references The provisions of the following documents are referenced in this part by T/SOECC and become part of this document. For dated referenced 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 referenced documents, the latest version applies to this part. T/SOECC 005.1-2022 Enameled Round Wire for Winding, Part 1: General Provisions 3 Definitions, test m
