IEC 60137:2017 RLV包含国际标准及其红线版本。红线版本只有英文版本。Redline版本为您提供了一种快速简单的方法来比较该标准与其前一版本之间的所有变化。红线版本不是IEC官方标准，只有标准的当前版本才被视为官方文件。 IEC 60137:2017规定了绝缘套管的特性和测试。 本标准适用于第3条中定义的套管，用于电气设备、机械、变压器、开关设备和三相交流系统的装置，设备的最高电压高于1000 V，电源频率为15 Hz至60 Hz（包括60 Hz）。 根据买方和供应商之间的特别协议，本标准可以部分或全部适用于以下情况:-用于三相系统以外的系统的衬套； -高压直流系统用套管； -用于测试变压器的套管； -电容器用衬套。 本标准中对变压器套管的特殊要求和试验也适用于电抗器套管。 本标准适用于单独制造和销售的衬套。作为设备的一部分且不能根据本标准进行测试的衬套应与作为其一部分的设备一起进行测试。与上一版相比，此版本包括以下重大技术变更: -已推出树脂浸渍合成(RIS)衬套。 -引入了Um≤1.1 kV、Um=1100 kV和Um=1200 kV的套管。 -已包括液体温升试验-根据第3.4条的绝缘衬套。 -引入干式雷电脉冲测试，作为Um>72.5 kV的所有变压器套管的常规测试。 -修订了海拔修正程序（>1 000米）。 -包括关于极快瞬态（VFT）现象及其对衬套影响的解释。

IEC 60137:2017 RLV contains the International Standard and its Redline version. The Redline version is available in English only. The Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. The Redline version is not an official IEC Standard, only the current version of the standard is to be considered the official document.

IEC 60137:2017 specifies the characteristics and tests for insulated bushings.
This standard is applicable to bushings, as defined in Clause 3, intended for use in electrical apparatus, machinery, transformers, switchgear and installations for three-phase alternating current systems, having highest voltage for equipment above 1 000 V and power frequencies of 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 reactor bushings.
This standard is applicable to bushings made and sold separately. Bushings which are a part of an apparatus and which cannot be tested according to this standard should be tested with the apparatus of which they form part. This edition includes the following significant technical changes with respect to the previous edition:
- Resin-impregnated synthetic (RIS) bushings has been introduced.
- Bushings with Um ≤ 1,1 kV, Um = 1100 kV and Um = 1200 kV have been introduced.
- Temperature rise testing has been included for liquid-insulated bushings according to clause to 3.4.
- Introducing dry lightning impulse testing as a routine test for all transformer bushings with Um > 72,5 kV.
- The altitude correction procedure has been revised ( > 1 000 m).
- An explanation about Very Fast Transient (VFT) phenomenon and its impact on bushings has been included.
