Distribution composite line post insulator

Distribution composite line post insulator products are intricately designed by using top quality of basic material and including updated technology and tools.

Composite insulator consists of FRP core, sheds and housing. Its shed can be divided into large sheds and small sheds. Orient’s housing of polymeric insulator is directly injected at high temperature and high pressure on the fiberglass rod and the fittings, assuring a complete adherence and strong bonding of the silicone rubber of polymeric insulator. Distribution composite line post insulator is called composite insulator since it has three parts made together.

The entire process ensures high grade insulator rods with narrow manufacturing tolerances and excellent mechanical and dielectrical properties. The end seal adopted the high temperature sulfuration to ensure the reliable sealing performance of the metal fitting.

Both the bottom surface and top surface of the distribution composite line post insulator sheds are inclined. This ensures optimal creepage distance and protected areas, resulting in the lowest possible leakage currents, even in severe environments. The silicone rubber is over mounded on injection onto the fiber glass core rod.

An engineering milestone, which shows Orient Power’s capabilities, was the design and manufacture of the distribution composite line post insulator for electrical railway for China's ministry of railways using composite insulators technology in 1998.
