What is polymer insulator?
Polymer insulator is a kind of insulator with polymer insulation parts, and it is also named also named composite insulators, silicone rubber insulator. Usually, the insulation parts are made of silicone rubber, Al(OH)3 and fillers. This kind of insulators have the same function of glass insulators and ceramic insulators, when applied for power systems with a voltage over 1000V.
Classification of polymer insulators
When classified by how the insulators are applied, they can be classified into:
- Polymer suspension insulator
- Polymer tension insulator
- Polymer line post insulator
- Polymer station post insulator
- Polymer pin type insulator
- Polymer spacers
