110KV disc composite suspension insulator meet hydrophobicity:
Orient 110KV disc composite suspension insulators are also available with silicone rubber to further improve their performance under pollution.
Surface contamination of a 110KV disc composite suspension insulator when installed in extreme environmental conditions increases the risk of leakage currents, which can subsequently lead to pollution flashovers and power system outages.

Providing a hydrophobic surface by adding an estimated 0.5 mm layer of RTV silicone rubber will limit the leakage current to harmless levels in the presence of moisture and contamination.

110KV disc composite suspension insulator Process:
To avoid leakage currents, discharges and pollution flashovers, a silicone layer is applied to the insulator surface by using a special spray coating technique. This silicone layer provides a hydrophobic surface, combating the negative effects of contamination and enhancing the electrical characteristics and low leakage currents in highly polluted areas.

110KV disc composite suspension insulator Hydrophobicity Transfer:
In the case of pollution particle deposition on the coated layer, the low molecular weight siloxanes will pread from the silicone bulk material to the pollution layer and encapsulate these particles within a short time period. Now the 110KV disc composite suspension insulators surface is hydrophobic again.
