Foreword

This European Standard was prepared by the Technical Committee CENELEC TC 36A, Insulated bushings.
It was submitted to the Unique Acceptance Procedure and was approved by CENELEC as EN 50181 on
2010-07-01.
This document supersedes EN 50181:1997.
The main technical changes on the Plug-in type bushings are:
– Enlarge the scope of the voltage class from the plug-in bushings from 36 kV to 52 kV;
– Upgrading the current capacity of the existing defined bushings;
– Introduce a new bushing interface for 52 kV.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent rights.
The following dates were fixed:
– latest date by which the EN has to be implemented

at national level by publication of an identical
national standard or by endorsement (dop) 2011-07-01

– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2013-07-01

Introduction
The object of this European Standard is to specify the requirements to ensure interchangeability of bushings
for maximum voltages above 1 kV up to 52 kV and rated currents from 250 A to 2 500 A for equipment 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.

This European Standard establishes essential dimensions, to ensure adequate mounting and
interchangeability of mating plug-in separable connectors of equivalent ratings.
