Polymer line post insulator,line post insulator polymer 20KV
Polymer line post insulator properties:
Line post insulator post 20KV is one main type of polymer line post insulator, which is applicable to high pressure line facilities. Line post insulator polymer 20KV has good hydrophobicity, aging resistance, tracking resistance and electrical erosion resistance. It also has high tensile strength and flexural strength, high mechanical strength, impact resistance, shock-proof and anti-brittle performance. Its mounting dimensions are corresponding with the polymer pin type installation, so it can be used interchangeably.

Line post insulator polymer 20KV formation:
Polymer line post insulator consists of three parts: an insulating mandrel, silicone rubber weathershed cover and connecting fittings at both ends.
The Core- Made of high-quality fiberglass reinforced Rod (FRP type).
End Fittings- Ductile iron after hot dip galvanization in accordance with IEC & ANSI standard.
Silicone Rubber Housing- HTV Silicone Rubber made of high quality raw materials.
Corona Ring- Made of High-grade Aluminum Alloy.
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.
