This document is applicable to plug-in type bushings, according to EN 60137, 72,5 kV, rated currents  from 630 A up to 1 250 A and frequencies from 15 Hz up to 60 Hz for single or three-phase arrangements  in electrical equipment like liquid filled transformers or gas insulated switchgear and controlgear. It  complements and amends, if necessary, the relevant EN standards.  The application of such plug-in type bushings is derived from EN 50180 and EN 50181 but applied for  higher voltages with described deviations to EN 50299-2 and EN 62271-209.  This standard does not cover the connection assembly as described in EN 50299-2 and EN 62271-209.  EN 60137 and HD 632 series outline the qualification, type test, routine and sample test of plug-in type  bushings according to this standard.  This document establishes essential dimensions and testing procedures, to ensure adequate mounting  and interchangeability of mating plug-in separable connectors of equivalent ratings.
