Technical Specification

Product: Transformer Bushing Assembly
Application: Liquid-Filled Transformers

1. Electrical Ratings

• Electrical ratings are based on use in liquid-filled transformers, with the lower end of the bushing submerged below the oil level.

2. Insulator Construction

• Material: High-quality electrical-grade wet-process porcelain
• Finish: Standard gray glaze, unless otherwise specified

3. Gaskets

• Standard Gasket: Nitrile (Buna-N)
• Optional Gasket: Cork and rubber composite
  • To specify this option, add suffix “C” to the part number when ordering

4. Terminal / Spade Assembly

• Material: Spade castings consist of 95% minimum conductivity copper
• Finish: Tin-plated for corrosion resistance and reliable electrical performance
• Optional Materials: Bushings can be furnished upon request with spades made of lower conductivity copper alloys, such as brass, bronze, etc., at a discounted price

5. Design Features

Designed to provide mechanical stability, rotational alignment, and long-term electrical reliability in transformer applications
