IEC/IEEE 65700-19-03:2014（en）适用于直流系统上使用的任何电压、电容分级或气体绝缘类型的室外和室内套管，用作充油换流变压器和平滑电抗器的组件，以及空对空直流套管。本标准参考IEC 60137的通用条款和条件，并定义了直流应用套管的专用术语、操作条件、额定值、试验程序以及一般机械和电气要求。 本标准取代IEC 62199:2004《直流应用套管》。

IEC/IEEE 65700-19-03:2014(en) 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 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. This standard replaces IEC 62199:2004, Bushings for DC application.
