EN 36/250/P3 Transformer Bushing Insulator 36kV
High Voltage Transformer Bushings
Product Overview
An EN pattern transformer bushing in the 36/250/P3 designation, rated 36 kV. It stands 600 mm tall and 155 mm across with 935 mm of creepage against a 465 mm arcing distance, weighing 6.8 kg. The creepage figure is the longest in this bushing range, which is what puts it on 36 kV transformers in heavily polluted air.
Key benefits
Why Buyers Choose This Part
- 935 mm creepage, the longest figure in the bushing range
- 465 mm arcing distance at the 36 kV class
- P3 profile designation for the heaviest pollution class
- 6.8 kg on a 600 mm body, manageable for a 36 kV part
Application scenarios
Where It Is Used
- 36 kV transformers in coastal or heavily industrial locations
- Substation transformers where wash access is difficult
- Networks upgrading insulation class after repeated flashover
- Projects specified against the EN pollution profile designations
Who it is for
Who It Suits
- Transformer manufacturers building for polluted environments
- Utilities operating 36 kV networks in coastal or industrial areas
- EPC contractors specifying by pollution class
Problems it solves
What Goes Wrong Without The Right Part
- Repeated pollution flashover at 36 kV on standard creepage bushings
- Wash programmes that cannot be scheduled often enough
- Creepage shortfalls that only appear after a season in service
- Terminal designs that need long creepage without excessive height

Comparison
How It Compares
| AS 24/315 | The AS part gives 450 mm creepage at 24 kV on a 505 mm body. The EN 36/250/P3 more than doubles the creepage for the 36 kV class. |
|---|---|
| DIN 30NF250 at 36 kV | Same voltage class on the DIN pattern. The P3 designation here identifies the long creepage pollution profile specifically. |
Use guide
Before You Order And After It Arrives
- Match the P profile designation to the site pollution class
- Allow 600 mm of clearance above the transformer cover
- Check the 155 mm diameter against the terminal board opening
- Wash with clean water only when deposits build on the long creepage surface
Questions
EN 36/250/P3 Transformer Bushing Insulator 36kV Questions
What is the creepage distance?
935 mm, with a 465 mm arcing distance. It is the longest creepage figure in this bushing range.
What does the P3 in the designation mean?
It identifies the creepage profile within the EN pattern. The P3 is the long creepage version, which is why it is specified for heavily polluted sites.
What are the dimensions and weight?
600 mm high, 155 mm in diameter, 6.8 kg.
What is the rated voltage?
36 kV.
When should I choose this over a shorter creepage bushing?
When the site has salt fog, cement dust or industrial fallout, or when wash access is difficult and the surface has to hold out between cleans.
Can you supply other profiles in the range?
Yes. Tell us the site pollution class and we will recommend the profile.
