RIP Bushing

Product Overview

Resin Impregnated Paper dry type condenser bushing, also known as RIP dry bushing, is an advanced insulation component used for high voltage power equipment. It is widely applied in power transformers, switchgear and substation systems. Compared with traditional oil-filled bushings, Wishpower RIP dry type condenser bushing features an oil-free insulation design, low partial discharge, high mechanical strength and improved operational safety, making it suitable for modern power grids requiring reliability, environmental protection and long service life.

Wishpower resin impregnated paper dry type condenser bushing is designed with a capacitive grading structure to control electric field distribution. The insulation body is made of resin impregnated paper, while the external insulation can be manufactured with composite silicone rubber sheds for excellent pollution resistance and outdoor performance.

Key advantages include:

• Oil-free dry insulation system with reduced leakage and fire risk

• Capacitive grading design for optimized electric field control

• Low partial discharge for long-term insulation reliability

• Composite silicone rubber housing with strong hydrophobic performance

• Lightweight structure compared with porcelain or oil-filled alternatives

• High mechanical strength for transformer and substation applications

• Customizable voltage rating, creepage distance, flange and conductor design

Core Features

1. Oil-Free Dry Insulation
   The RIP insulation system eliminates the need for insulating oil, improving environmental safety and reducing maintenance requirements.

2. Stable Electrical Performance
   The condenser structure helps distribute voltage evenly and minimizes electrical stress concentration.

3. Low Partial Discharge
   High-quality insulation processing ensures low partial discharge performance under high voltage operation.

4. Excellent Pollution Resistance
   Composite silicone rubber sheds provide hydrophobicity and reliable anti-flashover performance.

5. High Mechanical Strength
   The bushing is suitable for long-term operation under mechanical load, vibration and outdoor conditions.

6. Flexible Application
   It can be used for power transformers, GIS equipment, switchgear, wall-through systems and renewable energy substations.

Product Structure

The RIP dry type condenser bushing mainly consists of:

• Central conductor: Transfers current and can be made of copper or aluminum.

• RIP condenser core: Main insulation body made of resin impregnated paper.

• Capacitive grading layers: Control electric field and voltage distribution.

• Composite silicone rubber housing: Provides external insulation and weather resistance.

• Mounting flange: Connects the bushing to transformers, switchgear or wall structures.

• Terminal connection: Used for connection with busbars, cables or equipment terminals.

• Sealing system: Prevents moisture ingress and ensures insulation stability.
