Line post insulator

Line post insulator

As a professional line post insulator supplier, composite insulator line post consists of silicone rubber shed, housing, FRP core and metal end fittings.

The materials of composite insulators
Housing (Weathershed & Sheath) is 100% silicone rubber before adding fillers. The sheath and the weathersheds are formed at the same time from the same rubber mass by compression molding.

The best mixture of base polymer, fillers, and additive agents achieves an effective contamination, weather resistant, anti-tracking, and anti-erosion performance.

FRP Core of Line post insulator is high quality pultruded FRP (Fiber Reinforced Plastic) rod. The rod is made with excellent alignment and distribution of fibers within an Epoxy resin.

End Fittings are ductile iron in accordance with ASTM A536. All surfaces of the end fittings to be exposed to environmental conditions are galvanized in accordance with ASTM A153.

Bases are ductile iron (rigid type base) or rolled steel (bendable type base). All surfaces of the base are galvanized. Grading Rings are a high-grade aluminum alloy.
