Composite Station Post Insulators

A silicone polymer station post insulator mainly consists of a core rod (ECR type or FRP type), silicone rubber housing and flanges end fittings. WINNING® supplies station post insulators from 15kV to 345kV for the applications of power stations.

Core- Made of high-quality Pultruded Epoxy Rod (ECR type).

End Fittings- Ductile Iron after Hot Dip Galvanization in accordance with IEC & ASTM standard.

Silicone Rubber Housing- HTV Silicone Rubber made of high quality raw materials.

Sealing- Juncture between end fitting and Core rod is totally embedded in HTV silicon rubber, eliminating conventional and traditional sealing defects. (The other type is available that use RTV Silicone Sealant to seal the juncture between end fitting and core rod.)

Load Definitions:

CBL-Cantilever Breaking Load, is defined as the maximum load that is reached during a cantilever breaking test.

SCL-Specified Cantilever Load, is defined as the cantilever load rating that is assigned by the manufacturer.
