Polymer insulator

Composite tension & suspension insulator mainly consists of a core rod (ECR type or FRP type), silicone rubber housing and metal end fittings.

Material of end fittings: #45 forged steel, hot dip galvanized,thickness of the galvanization: ≥86μm

Material of the core: Epoxy & glass fiber (ECR type or FRP type).

Material of the weather sheds: HTV silicone, color grey

Housing to core: They are chemically bonded and the interface strength between the housing and core is higher than the tearing strength of housing itself.

Sealing: Juncture between end fitting and core rod is totally embedded in HTV silicone 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).
