11 kv post insulators are made from porcelain materials. Porcelain post insulators should be coated with RTV silicone rubber coatings to improve hydrophobic.
Coated RTV silicone rubber coatings, we should do
◆ Understand different porcelain insulator with coating materials and without coating material
◆ Contamination level on outdoor insulators
◆ Sample preparation flashover phenomena on outdoor insulators
◆ Artificial contamination procedure
◆ Measurement of insulator contamination level
◆ Laboratory experiments: surface resistance measurement, flashover test results
11 kv post insulators is normally used small transformer with small bushing insulator, the operation voltage is 11kv. 11 kv post insulators are also made of polymer materials, which is important polymer insulators.
11 kv post insulators can be divided into indoor post insulators and outdoor post insulators. Outdoor post insulators are popular electrical insulators for substations or power plant.
