Post Insulator

Porcelain post insulators are used on substations and apparatus. The post insulators will be made into several stacks according to the height. If the height is too high, we will produce this with two or more units and stack them together.

Height is important for porcelain post insulators, since they need assemble with other electrical parts, and lightning impulse withstand voltage is also important. According to different application place, clients also have requirement for the canlilever strength, compression strength and torsional strength.

End fittings can be cap type or flange type. The bolt cricle is important for the assembly.
