T/SOECC 005-7-2022 Aluminum copper-clad polyimide enamelled round wire for high-voltage equipment Part 7: Aluminum copper-clad polyimide 240 grade azo-based polyimide enamelled round wire

Scope

Main Technical Content: Copper-Clad Aluminum Round Coil Winding Wire Part 7: 240 Grade Aromatic Polyamide Copper-Clad Aluminum Round Wire 1 Scope This part specifies the requirements for 240-grade copper-clad aluminum round wire with a single coating based on aromatic polyamide resin. 240 grade indicates thermal resistance, requiring a minimum temperature index of 240°C and a thermal shock temperature of at least 260°C. The Celsius temperature corresponding to the temperature index does not necessarily represent the recommended operating temperature of the 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, 2.000 mm and below; - Grade 2: 0.071 mm and above, 5.000 mm and below. The nominal diameter of the conductor shall comply with the provisions of Clause 4.2 of Part 1. 2 Normative Reference Documents The provisions of the following documents are incorporated by reference into this part through T/SOECC: - Documents with a date of publication: All subsequent amendment bulletins (excluding errata) or revised editions shall not apply to this part. However, parties reaching agreements based on this part are encouraged to consider whether the latest versions of these documents can be used. - Documents without a publication date: Their latest versions shall apply to this part.
