HIGH CURRENT BUSHING ASSEMBLIES 2.5 kV CLASS, 60 kV B.I.L., 4.00″ MIN CREEP SIDEWALL OR COVER MOUNTED

Technical Specification

Product: High Current / Liquid-Filled Transformer Bushing Assembly
Application: Liquid-Filled Transformers

1. Operating Conditions

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

2. Construction and Materials

• Insulating Body: Manufactured from premium electrical-grade wet-process porcelain to provide high dielectric strength and mechanical durability.
• Finish: Standard gray glaze, unless otherwise specified.
• Mounting Hole Diameter: 3.38 in (85.9 mm) minimum.

3. Gaskets

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

4. Terminal (Spade) Assembly

• Standard Material: 95% minimum conductivity copper.
• Finish: Tin-plated for corrosion resistance and improved electrical performance.
• Optional Materials: Lower conductivity copper alloys (e.g., brass, bronze) available upon request at discounted pricing.

5. Design Features

• Designed for externally clamped mounting in transformer applications.
• Provides mechanical stability, rotational alignment, and long-term electrical reliability.
