This standard is applicable to inlet capacitive bushings operating in AC systems with nominal power < 126kv~550kv and frequency not exceeding 100Hz. This standard applies to capacitive bushings supplied separately in transformers and also to wall-mounted bushings. Capacitive bushings can be divided into oil-impregnated paper type, cross-adhesive paper type and other types according to their insulation structure. This standard specifies the technical conditions, testing and acceptance standards for imported capacitive bushings.
