AS 15/50 Transformer Bushing Insulator 15kV
High Voltage Transformer Bushings
Product Overview
An Australian Standard AS 15/50 transformer bushing rated 15 kV, 485 mm tall and 101 mm in diameter. Creepage is 310 mm against a 157 mm arcing distance, and the unit weighs 2.8 kg. It is the entry point of the AS bushing range, sized for the terminal boards used on Australian Standard distribution transformers.
Key benefits
Why Buyers Choose This Part
- 310 mm creepage against a 157 mm arcing distance at 15 kV
- Slim 101 mm diameter for tight terminal board spacing
- 2.8 kg unit weight keeps transformer cover loading low
- Australian Standard pattern supplied alongside DIN, EN and ANSI ranges
Application scenarios
Where It Is Used
- 15 kV distribution transformers built to Australian Standard
- Export projects following AS rather than IEC or ANSI
- Terminal boards with limited spacing between phases
- Replacement of installed AS 15/50 bushings
Who it is for
Who It Suits
- Transformer manufacturers working to Australian Standard
- Utilities in markets that follow AS specifications
- Distributors supplying AS pattern bushings
Problems it solves
What Goes Wrong Without The Right Part
- AS pattern parts that IEC and ANSI suppliers do not carry
- Phase spacing limits that a wider bushing would breach
- Creepage shortfalls at 15 kV in outdoor service
- Long import lead times on Australian Standard hardware

Comparison
How It Compares
| AS 24/315 | The 24/315 is 505 mm tall and 108 mm across with 450 mm creepage at 4.5 kg, for the 24 kV class. Match the AS designation to the network voltage. |
|---|---|
| ANSI-15/50 bushing | The ANSI-15/50 is 485 mm tall with 310 mm creep distance at 2.8 kg on the ANSI pattern. Comparable size, different standard, so order by the one on your drawing. |
Use guide
Before You Order And After It Arrives
- Confirm the drawing calls for the AS designation
- Check the 101 mm diameter against the terminal board opening
- Allow for the 485 mm height above the transformer cover
- Keep the creepage surface clean in outdoor service
