ANSI 15kV Transformer Porcelain Bushing
Screw Thread Transformer Bushings
Product Overview
A 15 kV transformer porcelain bushing built to ANSI electrical and mechanical performance requirements. It gives the high voltage supply a safe passage into the transformer and forms the interface that protects the equipment from arcing damage. The shed profile is streamlined, which cuts the chance of flashover and helps heat dissipate from the terminal area.
Key benefits
Why Buyers Choose This Part
- Meets ANSI standards for both electrical and mechanical performance
- Streamlined profile that reduces flashover likelihood
- Improved heat dissipation around the terminal connection
- High-quality porcelain built for harsh outdoor environments
Application scenarios
Where It Is Used
- Power transformers at 15 kV in generation, transmission and distribution
- Switchgear and other electrical equipment needing an ANSI bushing interface
- Outdoor installations exposed to harsh weather
- Projects specified against ANSI rather than DIN or EN
Who it is for
Who It Suits
- Transformer manufacturers working to ANSI specifications
- Power generation, transmission and distribution operators
- Switchgear builders needing an ANSI-compliant bushing
Problems it solves
What Goes Wrong Without The Right Part
- Electrical arcing damage at the high voltage interface
- Flashover on bushings with a shed profile that traps dirt
- Heat build-up at the terminal under continuous load
- Non-ANSI parts offered where the specification requires compliance

Comparison
How It Compares
| DIN pattern bushing at the same voltage | ANSI and DIN fix different dimensions and test values. Specify the one your transformer drawing follows, they are not interchangeable at the terminal board. |
|---|---|
| 18 kV ANSI transformer bushing | Same ANSI family, a step up in voltage class. Match the bushing class to the transformer HV rating. |
Use guide
Before You Order And After It Arrives
- Confirm the transformer drawing calls out ANSI before ordering
- Match the thread size to your terminal stud
- Keep the shed surface clean to preserve the flashover margin
- Check the seal at the tank interface during every service
