Product Description

Product Description

Nanjing Rainbow Electric Co., Ltd Condenser bushings product are classified as Wall Bushing, Transformer Bushing, GIS Lead-out Bushing, Oil/Oil bushing that connecting transformer and oil-filled equipment, Oil/SF6 bushing that connecting transformer and GIS. According to the capacitive main insulation,product are classified as Oil Impregnated Paper (OIP) Capacitor Bushing, Resin Impregnated Paper(RIP) Bushing, Glassfiber Reinforced Plastic (GFRP) Dry-type Bushing and Vacuum Epoxy Resin Impregnated Fiberglass (RIP) Capacitor Bushing.
 

 

Oil-Impregnated Paper (OIP) bushings are common high-voltage insulation components in power systems, mainly used in transformers and switchgear.

 

It has higher voltage compared with Epoxy Resin Bushing, the common voltage class for OIP Bushings are 72.5kV, 145kV, 252kV 363kV, 420kV and 550kV. The outer insulation is porcelain or silicone rubber, we could design according the the requirements of the customer.
