Application Summary AI generated
This standard specifies the technical requirements, test methods, and inspection rules for accessories (such as joints, terminations, and connectors) used with 500kV cross-linked polyethylene (XLPE) insulated power cables. It is applied in high-voltage power transmission systems, specifically for the installation and performance verification of cable accessories in ultra-high-voltage (UHV) power grids and large-scale substations. The standard ensures the reliability and safety of these critical components under rated voltage conditions (Um=550kV).
