4-2002 IEC 60502-4 Technical parameters:Power frequency withstand voltage:117kV/5mins Partial discharge :45kV<10pCStandard :GB/T12706. Thermal withstand ensures the busbar temperature does not exceed the short-time limit (250 degrees C for copper per IEC 61439-1) during a fault: A >= I x sqrt (t) / k, where k = 143 for copper (or use 13 for Aluminium. Suitable for the high voltage electrical apparatus of power plant, power transformer station at or under 35kV, such as cable branch box, combination transformer and incoming / outgoing line of GIS system.
