Station Post Insulators: An Emerging Application for Composite Hollow Core Insulators

Station Post Insulators (SPI)

Are an emerging application for Composite Hollow Core Insulators. The handling of their inside, a topic of more serious regard compared to the traditional applications, is known and well defined. Ongoing standardization work within IEC will issue a new product standard (IEC 62772) very soon, by that eliminating the lack of standardization for that comparatively new application.

Since their introduction in the 80’s, composite hollow core insulators have taken an important position in the various fields of application for high voltage insulation technique, such as cable terminations, bushings, insulators for VTs/CTs, LTB and DTB etc. Although the application penetration is high, new applications are considered, in which the traditional ceramic versions are forming the today’s standard. This paper points out the approach of establishment for composite hollow core technique in the station post application environment, and highlights some technical considerations made when adapting the well-introduced composite hollow core technique to the particular needs of this new application.
