適用范圍：This recommendation applies to bushings as defined in Section Two, Definitions.This recommendation applies to bushings supplied separately, for use in the construction of electrical apparatus, machines, transformers and electrical installations. It also applies to bushings supplied as an integral part of apparatus when required by the corresponding apparatus recommendation.This recommendation applies to bushings for three-phase alternating current systems, having rated voltages above 1 000 volts and frequencies between 15 Hz and 60 Hz.The application of this recommendation to bushings for other than three-phase systems shall be subject to special agreement.This recommendation does not apply to bushings for use with mercury vapour rectifiers or to bushings in which the major insulation consists of gas other than air at atmospheric pressure. Such bushings shall be subject to special agreement.Note. — If the bushing, due to its design or use, cannot be tested separately under the conditions specified in this recommendation, the test procedure is to be asreed upon between purchaser and supplier.
