Scope

Main technical content: This document specifies the operating conditions, structural forms, technical requirements, test items, test requirements, and inspection rules for epoxy-impregnated fiber insulating bushings. This document is applicable to transformers, switches, reactors, box transformers, and other electrical equipment used in three-phase AC systems with a maximum voltage of (1–550) kV and a frequency of 50 Hz. By agreement between the supplier and the buyer, parts or all of this document are applicable to the following bushings: — bushings with a maximum voltage higher than 550 kV or bushings used in non-three-phase AC systems; — bushings used in high-voltage DC systems; — bushings used in test transformers; — bushings used in capacitors. The special requirements and tests for transformer bushings in this document also apply to reactor bushings. This document is applicable to bushings that are manufactured and sold separately. Bushings that form part of electrical equipment and cannot be tested according to this document should be tested together with the electrical equipment.
