Medium voltage Composite Insulators offer the ultimate solution in improved performance.Because of its hydrophobicity, this material inherently resists water filming thereby limitingleakage 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 insulators.

Application: MV composite Insulators are used on overhead lines operating at or below 69 kV. These insulators are used to support line conductors such as line terminations, angles, and tangents. With the special head design, these insulators can be used with bare or covered conductors. 

Component: MV composite 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.
