绕组线试验方法 第7部分：测定漆包绕组线温度指数的试验方法
Application Summary AI generated
This standard specifies the test procedure for determining the temperature index of enamelled winding wires, which is a measure of their thermal endurance. It is applied in the electrical engineering industry to evaluate and classify the long-term heat resistance of magnet wires used in motors, transformers, and other electromagnetic devices. The test method is critical for quality control and material selection in applications where wires are subjected to sustained high operating temperatures.
