Composite Line Post Insulators offer the ultimate solution in improved performance. Because of its hydrophobicity, this material inherently resists water filming thereby limiting leakage currents. Insulators with reduced leakage currents, even when contaminated, require less frequent washing. The savings in such maintenance costs are added benefits of using silicone.

Application: Composite Line Post Insulators are used on overhead lines operating at or below  230 kV.  These insulators are used to support line conductors such as line terminations, angles, and  tangents. With the special fitting design, these insulators can be installed at steel tower or  wooden pole used with bare or covered conductors. 

Component: Composite Line Post Insulators are consisted of E-CR fiber reinforced polymer  rod, metal fitting and housing materials. The glass must be electrically and chemically stable  (ECR glass) and the housing(including the sheath and sheds) must be HTV silicone rubber with  high hydrophobicity and high tracking & erosion resistance performance. 

Technology Innovation: For HTV SR, CYG has its own patent formula and its own patent of the  production process; For process, CYG creats the unique whole molding injection/sealing
