Applications
Where our insulators and bushings are typically used.
- Overhead distribution and transmission lines
- Substation busbars
- Transformer and switchgear spares
- Coastal and polluted environments
Before you request a quote
- Pollution level
- Specify site pollution severity so creepage distance is adequate.
- Mechanical load
- Give the specified mechanical load for line insulators.
- Material
- Polymer insulators are lighter and perform well in pollution.
Insulators and Bushings: common questions
More answers on the FAQ page.
Polymer insulators are lighter and resist pollution well; porcelain has a long service record and is still widely specified.
The surface distance along the insulator, increased for polluted or coastal sites to prevent flashover.
Yes, bushings can be supplied to match transformer ratings and dimensions.
