ActiveResidual strength of string insulator units of glass or ceramic material for overhead lines after mechanical damage of the dielectric
架空线路玻璃或瓷绝缘子串元件绝缘体机械破损后的残余强度
Application Summary AI generated
This standard specifies the test method for determining the residual mechanical strength of glass or ceramic string insulator units used in overhead power lines after their dielectric material has been mechanically damaged. It is applied by manufacturers and testing laboratories to evaluate the safety margin and structural integrity of insulators that have sustained impact or cracking, ensuring they can still withstand operational loads in high-voltage transmission networks.
