POWER BUSHING ASSEMBLIES 8.7 KV CLASS, 95 KV BIL, 11.5″ CREEP
Technical Specification
1. Application
Designed for use in transformers, switchgear, entrance, and special power apparatus applications.
2. Electrical Ratings
- Ratings are based on use in a liquid-filled transformer, with the lower end of the bushing submerged below the oil level.
3. Construction
- Insulator Material: High-quality electrical-grade wet-process porcelain.
- Finish: Gray glaze applied over the entire porcelain surface.
- Top Skirts: Designed for outdoor applications.
- Sealing: Bushings are fully oil- and watertight at both the top terminal and mounting flange.
4. Terminal / Spade Assembly
- Material: Pure copper spade castings, tin-plated.
- Electrical Conductivity: Minimum 97% guaranteed.
5. Mechanical Components
- Flanges and Washers: Constructed from non-magnetic materials.
- Disc Spring Assembly: Maintains constant gasket pressure at the top terminal, compensating for thermal expansion and contraction of the copper stud.
