标称电压高于1000V的架空线路用绝缘子----直流系统用瓷或玻璃绝缘子元件----定义、试验方法和接收准则
Application Summary AI generated
This standard defines the terminology, test methods, and acceptance criteria for ceramic or glass insulator units specifically designed for direct current (d.c.) overhead power lines operating above 1000V. It is applied by manufacturers and testing laboratories to verify the electrical and mechanical performance of these insulators under d.c. voltage stress, ensuring reliability in high-voltage d.c. transmission systems.
