33kV Silicone Pot Insulator
Silicone composite pot insulator for 33kV mounting positions
Product Overview
At 33kV a pot insulator has to deliver the creepage the class requires within a compact base mounted form, which is a harder combination than it sounds. The silicone housing is what makes it workable in polluted air: a shorter physical path performs better when the surface refuses to hold a continuous water film.
Key Benefits
- 33kV support insulation in a compact base mounted form
- Hydrophobic surface compensates where physical creepage is constrained
- Composite construction lighter and tougher than the ceramic equivalent
- Base arrangement matched to the equipment it mounts on
Problems It Solves
- Achieving 33kV creepage in a height constrained position
- Surface tracking on compact insulation in polluted air
- Ceramic pot insulators failing under mounting and thermal stress
Application Scenarios
- 33kV equipment and switching mounting positions
- Height constrained support positions
- Coastal and industrial 33kV installations
- Replacing ceramic pot insulation on existing equipment
Who It Is For
- 33kV distribution operators
- Substation and switchgear contractors
- EPC companies
- Maintenance departments upgrading polluted positions
Technical Features
- Silicone rubber composite construction
- Pot form with base mounting
- Rated at 33kV
- Compact height with the required creepage

Compared With Other Options
| 11kV pot insulator | The same form at the lower class. System voltage decides. |
|---|---|
| 33kV standoff insulator | A standoff gives more creepage in a taller form. Where height is available, it is often the easier answer. |
Use Guide
- Confirm the pollution severity as well as the voltage before selecting
- Check the base fixing pattern against the equipment
- Mount square and check fixings after the first thermal cycle
- Inspect for surface tracking at maintenance visits

33kV Silicone Pot Insulator Questions
Is a pot insulator suitable for a heavily polluted 33kV position
Describe the environment with the enquiry. Where the physical creepage available is tight, the environment decides whether a pot or a taller standoff is the right answer.
Can the base fixing be matched to our equipment
Yes. Send the equipment drawing or the installed part.
Can I order 11kV and 33kV pot insulators together
Yes - mixed class quantities go on one line list.
