Product Description

Product Description
  1.  FCRG dry type composite capacitive type wall bushings is an independently developed and innovated product in China; The main insulation inside the casing is divided into two types: composite film capacitor main insulation and rubber immersed fiber capacitor main insulation.The external insulation is divided into high-temperature vulcanized silicone rubber composite jacket and porcelain jacket, which can meet the needs of different users;
  2.   Based on standards:lEC60137.GB/T4109;
  3.   Product features: non oil filled, non air filled, fireproof, explosion-proof, environmentally friendly, maintenance free, and strong pollution resistance; The composite film capacitive sleeve has a relatively lighter weight, while the adhesive impregnated fiber capacitive sleeve has a relatively stronger mechanical strength;
  4.   Main technical parameters:
  4.1 Environmentaltemperature:-40~+55°C
  4.2 Rated voltage:12kV~363kV
  4.3 Rated current: 10A~8000A

  Nanjing Rainbow Electric Co., Ltd Condenser bushings products are classified as Wall Bushing, Transformer Bushing, GIS Lead-out Bushing, Oil/Oil bushing that connects transformer and oil-filled equipment, and Oil/SF6 bushing that connects transformer and GIS. According to the capacitive main insulation, products 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.
