This International Standard applies to outdoor and indoor bushings of any voltage used on DC
systems, of capacitance graded or gas insulated types for use as components of oil-filled
converter transformers and smoothing reactors, as well as air-to-air DC bushings. This
standard does not apply to the following:
• cable terminations (potheads);
• bushings for instrument transformers;
• bushings for test power supplies;
• bushings applied with gaseous insulation (other than air at atmospheric pressure) external
to the bushing;
• bushings for industrial application;
• bushings for traction application;
• bushings for distribution class transformers.
This standard makes reference to IEC 60137 for general terms and conditions and defines the
special terms used, operating conditions, ratings, test procedures as well as general
mechanical and electrical requirements for bushings for DC application.dition 1.0 2014-07 INTERNATIONAL STANDARD Bushings for DC application IEC/IEEE 65700-19-03:2014-07(en) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2014 IEC, Geneva, Switzerland Copyright ？ 2014 IEEE All rights reserved.
