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.
