Scope

This document specifies the general requirements for epoxy resin composites and their components (epoxy resin, curing agent, and α-alumina filler) used for casting high-voltage bowl-type insulators (hereinafter referred to as "insulators"), as well as testing items and technical requirements, test methods, inspection categories and items, packaging, labeling, storage, and transportation, etc. This document is applicable to the material selection of insulators in GIS (gas-insulated metal-enclosed switchgear) and GIL (gas-insulated metal-enclosed pipeline busbar) equipment. The material selection of pillar insulators and cast insulator support rods can be used as a reference.
