AS 24/315 Transformer Bushing Insulator 24kV
High Voltage Transformer Bushings
Product Overview
An Australian Standard AS 24/315 transformer bushing rated 24 kV, 505 mm tall and 108 mm in diameter. Creepage is 450 mm with a 251 mm arcing distance, and the unit weighs 4.5 kg. Against the AS 15/50 it adds 140 mm of creepage and nearly 100 mm of arcing distance for only 20 mm more height.
Key benefits
Why Buyers Choose This Part
- 450 mm creepage with a 251 mm arcing distance at 24 kV
- Only 20 mm taller than the 15 kV part despite the extra creepage
- 108 mm diameter still suits closely spaced terminal boards
- Australian Standard pattern available with DIN, EN and ANSI ranges
Application scenarios
Where It Is Used
- 24 kV distribution transformers built to Australian Standard
- Networks stepping up from 15 kV to 24 kV on existing terminal layouts
- Outdoor terminals needing longer creepage at 24 kV
- Replacement of installed AS 24/315 bushings
Who it is for
Who It Suits
- Transformer manufacturers working to Australian Standard
- Utilities operating 24 kV AS-specified networks
- Distributors supplying AS pattern bushings
Problems it solves
What Goes Wrong Without The Right Part
- Creepage shortfalls when a 15 kV bushing is reused at 24 kV
- Height clearances that a much taller bushing would breach
- AS pattern parts unavailable from IEC-focused suppliers
- Mixed voltage classes across one transformer fleet

Comparison
How It Compares
| AS 15/50 | The 15/50 gives 310 mm creepage and a 157 mm arcing distance at 2.8 kg. The 24/315 adds 140 mm of creepage for 20 mm more height and 1.7 kg more weight. |
|---|---|
| EN 36/250/P3 | The EN part reaches 36 kV with 935 mm creepage on a 600 mm body. Move up to it only if the network runs at 36 kV. |
Use guide
Before You Order And After It Arrives
- Do not reuse a 15 kV bushing at 24 kV, the creepage is not sufficient
- Check the 505 mm height against the transformer cover clearance
- Confirm the 108 mm diameter fits the terminal board opening
- Keep the longer creepage surface clean to preserve the margin
