IEC 62217:2025 pdf download,Polymeric HV insulators for indoor and outdoor use – General definitions, test methods and acceptance criteria.

IEC 62217:2025 applies to polymeric insulators designed for use in both AC and DC electrical systems. These insulators are defined by their insulating body, which is composed of one or multiple organic materials. Specifically, the standard covers:

For AC systems: Those with a nominal voltage exceeding 1,000 V and a frequency below 100 Hz.
For DC systems: Those with a nominal voltage exceeding 1,500 V.

The polymeric insulators within the scope of this document are intended for use in high-voltage (HV) overhead power lines and substations, and are suitable for both indoor and outdoor applications.
