IEC 60137:2008 pdf free download Insulated bushings for alternating voltages above 1 000 V
1 scope
This International Standard specifies the characteristics and tests for insulated bushings.
This standard is applicable to bushings, as defined in Clause 3, intended for use in electricalapparatus，machinery, transformers,switchgear and installations for three-phase alternatingcurrent systems, having highest voltage for equipment above 1 000 V and power frequenciesof 15 Hz up to and including 60 Hz.
Subject to special agreement between purchaser and supplier, this standard may be applied,in part or as a whole, to the following:
.bushings used in other than three-phase systems;
bushings for high-voltage direct current systems;bushings for testing transformers;
. bushings for capacitors.
Special requirements and tests for transformer bushings in this standard apply also to reactorbushings.
This standard is applicable to bushings made and sold separately.Bushings which are a partof an apparatus and which cannot be tested according to this standard should be tested withthe apparatus of which they form part.

3Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
bushing
device that enables one or several conductors to pass through a partition such as a wall or atank,and insulates the conductors from it; the means of attachment (flange or fixing device)to the partition forms part of the bushing
[IEV 471-02-01]
NOTE 1 The conductor may form an integral part of the bushing or be drawn into the central tube of the bushing.NOTE 2 The bushing may be of the types as described in 3.2 to 3.21.
