18、ment other than insulating liquid filled transformers. 1 Scope This European Standard is applicable to insulated bushings for maximum voltages above 1 kV up to 52 kV, rated currents from 250 A up to 2 500 A and frequencies from 15 Hz up to 60 Hz for equipment other than liquid filled transformers. T
19、his European Standard establishes essential dimensions, to ensure adequate mounting and interchangeability of mating plug-in separable connectors of equivalent ratings. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated referen
20、ces, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

21、technical product standards NOTE It is highly recommended to minimize the impact of bushings on the environment during all phases of their life (including manufacturing, operation during service life, dismantling after their end of life and disposal or recycling). IEC Guide109 and document by CENELE
22、C TC 111X, Environmental standardization for electrical and electronic products and systems after finalization can be used as helpful reference. 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 plug in type bushing bushing one end of which is
23、immersed in an insulating medium which has customized dimensions according to insulation requirements for the specific application and the other end designed to receive a separable insulated cable connector without which the bushing cannot function 3.2 separable connector fully insulated termination
24、 permitting the connection and disconnection of the cable to and from the mating plug-in type bushing 3.3 interface type bushing dimensions that insure mechanical and electrical interchangeability of bushing and separable connector of similar rating and type NOTE Each interface type is designed by a
25、 letter or a number. 3.4 bail holder fixture which facilitates anchoring of an externally mounted device (called the bail) designed to prevent undesirable separation of a separable connector and a bushing 1)Under development.
