HIGH CURRENT BUSHING ASSEMBLIES 5 KV CLASS, 75 kV B.I.L., 5.00″ MIN CREEP SIDEWALL OR COVER MOUNTED

Technical Specification

Product: Transformer Bushing Assembly
Application: Liquid-Filled Transformers

1. Electrical Ratings

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

2. Construction

• Insulator Material: High-quality electrical-grade wet-process porcelain.
• Finish: Standard gray glaze, unless otherwise specified.
• Mounting Hole Diameter: 3.38 in (85.9 mm) minimum.
• Anti-Rotation Design: The bushing is keyed to the two-piece clamp, and the connector is keyed to the porcelain insulator to prevent rotation.

3. Gasket Options

• Standard: Nitrile (Buna-N)
• Optional: Cork and rubber composite (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 reliable electrical contact.
• Optional Materials: Lower conductivity copper alloys (e.g., brass, bronze) available upon request at discounted pricing.

5. Design Features

Provides mechanical stability, rotational alignment, and long-term electrical reliability.

Designed for externally clamped mounting in transformer applications.
