IEC 62896:2024适用于大于1 000 V AC和1 500 V DC的AC和DC应用的混合绝缘子，由由陶瓷或玻璃组成的承重绝缘实心或空心芯、由聚合物材料制成的外壳（确定的几何形状，在绝缘芯外部）和永久连接到绝缘芯的端部配件组成。 本文件涵盖的混合绝缘子旨在用作悬挂/张力长杆和帽和销型绝缘子、线路柱绝缘子、站柱绝缘子和设备用空心绝缘子。 本文件的目的是: -定义所使用的术语； -规定测试方法； -规定验收标准 本文件不包括针对特定操作条件选择绝缘子的要求。第一版取消并取代了2015年发布的IEC TS 62896。与上一版相比，此版本包括以下重大技术变更: -术语和定义的修改； -IEC TR 62039和IEC 62217（疏水性转移试验）中包含的试验程序的修改； -表1（设计和型式变更后进行的试验）与其他产品标准和IEC 62217的协调。

IEC 62896:2024 applies to hybrid insulators for AC and DC applications greater than 1 000 V AC and 1 500 V DC consisting of a load-bearing insulating solid or hollow core consisting of ceramic or glass, a housing (defined geometry, outside the insulating core) made of polymeric material and end fittings permanently attached to the insulating core.
Hybrid insulators covered by this document are intended for use as suspension/tension long rod and cap and pin type insulators, line post insulators, station post insulators and hollow core insulators for apparatus.
The object of this document is to:
- define the terms used;
- prescribe test methods;
- prescribe acceptance criteria
This document does not include requirements dealing with the choice of insulators for specific operating conditions. This first edition cancels and replaces the IEC TS 62896 published in 2015. This edition includes the following significant technical changes with respect to the previous edition:
- modifications of terms and definitions;
- modifications of tests procedures included in IEC TR 62039 and IEC 62217 (Hydrophobicity transfer test);
- harmonization of Table 1 (Tests to be carried out after design and type changes) with other product standards and IEC 62217.
