High voltage Composite 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 insulators. 

Application: HV composite Insulators are used on overhead lines operating at or above 69 kV. HV Insulators from CYG are being widely used upto AC1000kV/DC1100KV EHV/UHV transmission lines. these insulators are working as the phase-spacer, jumper, cross-arm, line support, braced line supporter. 

Component: HV composite Insulators are consisted of E-CR fiber reinforced polymer rod, metal fitting and housing materials. For voltage above 110KV, the corona ring shall be installed to optimize the electrical strength. 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 process
