Product introduction
Composite dry bushing is a new type of wall bushing. Its inner insulation uses new insulation materials, and its outer insulation (silicone rubber shed) uses high-temperature vulcanized silicone rubber, which has good stain resistance. The seismic resistance and explosion-proof performance are in line with the development trend of oil-free and miniaturization in the power sector. It is a new generation of high-voltage power transmission and transformation products that meet the needs of urban and rural power grid transformation.
