126kV/630A OIP Condenser Bushings

Description

OIP condenser bushings are used in high-voltage electrical power systems to insulate and support the conductors that pass through transformer or reactor walls. They are typically made of a hollow cylindrical porcelain or composite housing filled with oil-impregnated paper insulation. The conductors pass through the center of the bushing and are electrically insulated from the bushing housing and other conductive components.

OIP condenser bushings provide a number of advantages over other types of bushings, including high reliability, long service life, and low maintenance requirements. They are also highly resistant to electrical and thermal stresses, making them ideal for use in high-voltage applications.

Production Range:

Voltage:  36kV,52kV,72.5kV,126kV,252kV and up 1000kV in two years.

Current: 400A,630A,1250A，2000A，3150A etc

OIP Condenser Bushings Main Characters：

1、Low-PD（partial discharge）：
   PD≤5pC @Um      ;      PD≤10pC @1.5Um   

2、Low Power Factor：
   Under voltage 1.05Um/√3        tanδ≤0.40％   Standard≤0.7%

3、Self-owned process of aluminum oil level gauge and flange(Ground tube) manufaturing, nice appearance and fine quality.

4、Test tap：
a、Alumina porcelain will not be damp for reliable insulation.
b、The spring is compressing the earthing devices for reliable  
grounding and to avoid misoperation. 
c、Entire sealing structure to prevent moisture.

5、The sealing structure of the top part, which is patented, can ensure that even if there is undue stress, minor misoperation, it will not lead to  the dangerous water fault.
