Welcome to Shandong ChinSun Electrical Equipment Co., Ltd.

Product Description: ChinSun OIP Transformer Bushing

The ChinSun OIP transformer bushing is a high-quality component designed for reliable operation in transformer systems. It consists of terminal blocks, oil conservators, upper/lower porcelain bushings, flanges, and equalizing shields.

The main insulation of the OIP transformer bushing features a cable paper wound capacitor core with a metal foil as the main insulation capacitor screen. This design ensures maximum *** voltage resistance and prevents partial discharge during operation.

Main Features:

• Compact structure for secure installation
• High-strength porcelain jacket insulation
• Oil conservator with oil level gauge for easy monitoring
• Customizable size options available

Installation Instructions:

1. Check oil level using the oil level gauge before installation
2. Maintain oil level within the specified range for optimal performance
3. Use compatible insulation oil for refilling or adjustment

Trust ChinSun OIP transformer bushing to ensure long-term reliability and efficient operation in your transformer systems.
