product description
[[[[产品参数, 参数]]]]
  The company can provide internal and external UHF partial discharge sensors, high-frequency current sensors, ground wave sensors, ultrasonic sensors, etc. according to different voltage levels and structures of GIS, transformers, switch cabinets and other requirements.
  At present, the company's ultra-high-frequency sensors have been used in many domestic UHV projects. In the test of one of the three largest domestic high-level organizations, our company's sensors perform well. Leak detection, insulation, lightning shock, A number of tests such as withstand voltage partial discharge and sensitivity, the test results are superior, and eventually used in the company's domestic UHV project. This is the first time that the company's UHV project has a built-in UHF partial discharge sensor with completely independent intellectual property rights. product.
