HIGH CURRENT BUSHING ASSEMBLIES 5 kV CLASS, 75 kV B.I.L., 5.00″ МIN CREEР SIDEWALL OR COVER MOUNTED

Technical Specification

Product: 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.
• Designed for reliable performance under standard transformer operating conditions.

2. Construction and Materials

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

3. Gasket Options

• Standard Gasket Material: Nitrile (Buna-N)
• Optional Gasket Material: Cork and rubber composite
  • To specify this option, 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 enhanced electrical performance.
• 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.
