11-36kV all kinds of pin insulators polymer pin insualtors composite pin insulators The company presently produces 1100kV and various voltage classes under 1100kV polymeric insulators. The products first passed the whole project test according to the latest standard GB/T19519-2004 "nominal voltage higher than 1000V AC overhead line polymeric insulators—definition, test method and acceptance criteria ",also IEC ANSI Standards and the test is done by the National Detection Center of Wuhan High Voltage Research Institute. Their mechanical performance and electrical performance surpass the national standards. And we can OEM all the brands as required by the client. The products have not only the good performance of the normal polymeric insulators, but also the following features: ●The technique of whole pressure injection is used for sheds and housing of silicon rubber composite insulator and has solved key problem of the influence reliability of polymeric insulators—interface electrical breakdown. ●Their mechanical strength is high. Epoxy glass fiber FRP rod bearing the internal load uses the ECR acid resistant core bar and has stronger anti-corrosive performance. ●The homemade unique three-step waterproof sealing technology and imported crossing linker have been used to fundamentally solve the problem of unsatisfactory sealing function at the ends of polymeric insulators and the internal insulation being moistened. ●The thickness of sheds and housing of silicone rubber is as twice as the requirement of the national standard and the material is chosen seriously.
