10kV~1000kV AC Products

Our factory's full range of 10kV-1000kV AC solid-core post porcelain insulators, produced using advanced isostatic pressing technology, covers all voltage levels from distribution networks, 110kV/220kV/500kV EHV, to 1000kV UHV AC substations. They are primarily used in scenarios such as disconnectors, circuit breakers, instrument transformers, and busbar supports in substations, serving dual roles of electrical insulation and mechanical support. They are core insulation equipment for power grid construction, power transmission, and grid renovation projects. The products strictly comply with national standards GB/T and IEC international standards, and can meet the supply requirements of domestic grid projects and overseas power bidding projects in multiple countries.
