Composite insulator line post type is used in rated voltage up to 132 kV power transmission and distribution lines for supporting, suspending and insulation and 33kv line post type insulators are common types.
33kv line post type insulators construction:
33kv line post type insulators consist of FRP core, sheds and housing. The composite line post insulator shed can be divided into large sheds and small sheds. The core rod is a corrosion resistant glass-fiber-reinforced rod. Galvanized end fittings designed to provide a large surface rubber bonding. The silicone rubber shed is made by excellent nature of hydrophobic material.
33kv line post type insulators tests:
Tests on Silicone Rubber: Tracking & Erosion Test, Volume Resistivity, Tensile and Tear Strength, Hardness (Shore A), U.V and Weathering Test and Dielectric Strength. Tests on FRP Rods: Specific Gravity, Glass Content, Water Diffusion Test and Dye Penetration Test. Tests On End Fittings: Thickness of Zinc Coating, Uniformity of Zinc Coating and Micro-structural of metal fitting.
