Composite Hollow Core Insulators

  • Chapter

Part of the book series: Power Systems ((POWSYS))

Abstract

Composite hollow core insulators (referred to hereinafter as HCI for short) are used primarily as housings for various high-voltage equipment and apparatus. Owing to their conditions for use, they primarily have to withstand bending and compression loads and since a large number of the electrical equipment are gas insulated (with SF6 and SF6 gas mixtures), they are also subject to internal pressure. Today, if the user so desires, it is possible to design complete substations in silicone composite technology.
