We offers a wide range of porcelain post insulators. For decades, these products have demonstrated reliable performance in various types of applications all over the world. Porcelain insulators are the traditional choice for distribution and transmission line, busbar and apparatus insulation. Manufactured from high-quality non-porous electrical porcelain, they provide long life and cost-effective solutions for a majority of applications.




Our insulators have externally attached caps or bases. a highly engineered cementing system transfers the load uniformly from the hardware into the porcelain body.


Porcelain body:


Each insulator body is made from the highest quality clay raw materials that have been processed to be fully vitrified porcelain . the body is glazed to add strength improve surface appearance, and enhance clean-ability.





Either chocolate brown or Munsell gray glaze is available. caps and flanges are ferrous , hot dip galvanized. thread holes are proper tapped.





post insulators are designed to provide rigid support of conducting cable while offering the maximum resistance to damage from electrical or mechanical events.
Horizontal and gain-base line post insulators are often used in applications to avoid the need to install a cross-arm on the pole.



Competitive advantages:


Reasonable insulation structure high reliability of inter-turn insulation.

Stainless steel flange low magnetic inductivity high resistivity.

Convenient transportation and flexible installation.

Low loss

Low temperature rise

High mechanical strength, strong weather ability.

Outstanding crack resistance

Low thermal expansion coefficient
