252kV Fiberglass dry-type transformer bushing (cable through type)Detailed product description：

The 252kV fiberglass dry-type transformer bushing (cable type) adopts fiberglass composite material for internal insulation and silicone rubber composite material for external insulation, which has many advantages such as oil-free, gas free, porcelain free, explosion-proof, environmentally friendly, maintenance free, and strong pollution flashover resistance. The capacitor core of this product adopts patented technology of stress splitting buffer lining, which greatly reduces internal stress, stabilizes product quality, and improves the product's ability to withstand cold and hot shocks and safe operation level.
