We have been committed to providing high-quality 38kV Composite Fuse Cut Body, Composite Post Insulators For Railway, 33kv Polymer Pin Insulator , and one-stop value-added services to our customers. If you are interested in any of our products, please contact us and we will provide you with more comprehensive details of the product. Adhere to independent innovation and take the development path of combining production, education and research. Since its establishment, the company has established a high starting point and a high-quality goal, focusing on talents, taking technology as the guide, and creating a brand with quality.

At present, composite polymer tension insulators are widely used in overhead power transmission lines, accounting for about 50% of the line silicone rubber insulator consumption. Composite polymeric insulators have solved the pollution flashover problem that has plagued the power grid for many years with their excellent anti-flashover performance.
Composite insulator rubber plays a vital role in the function of the insulator:

Application :

Product Advantage :
1.It has good anti-pollution performance and strong anti-pollution flashover ability. Its wet-resistant voltage and grid-resistant voltage are 2-2.5 times that of the same distance from the ceramic insulator, and it does not need cleaning, so it can operate safely in heavy pollution environment.
2.Good sealing performance, strong resistance to electrical corrosion, umbrella skirt material resistance to electrical leakage marks up to TMA4.5 level, with good aging resistance, corrosion resistance, low temperature resistance.
Wuhan Line Power has advanced production equipment and full range test facility.


Wuhan Line Power could provide kinds of packing methods for the clients, plywood case, solid wood case, carton box or as client requirement.
