What Is RTV Insulator Coating ?
Room Temperature Vulcanization (RTV)
Anti-Spatter Coating also be referred to as:
- High Voltage Insulator Coatings (HVICs)
- Anti-Tracking Coatings
- RTV Silicone Insulator Rubber (SIR) Coatings
For both AC and DC systems
For all the equipments up to 1200kV for both AC and DC
√ Superior adhesion;
√ Smooth surface finish;
√ Low surface free energy;
√ Very excellent hydrophobicity;
√ Maintenance free ;
√ No leakage current;
√ Environment-friendly ;
√ The most economical way to Prevent flashover ;
Pollution Flashover VS. The Grid Reliability
Extreme environmental conditions and high pollution areas such as heavy industrial, desert and coastal regions cause excessive leakage currents. The surface condition of insulator in such areas will subsequently lead to a pollution flashover and power system outages;
The cost of Insulators is just small part of transmission lines but insulators can impact the reliability of the whole power grids; Especially in coastal locations, more than 32.5% of failures are attributed to pollution flashovers; Pollution flashover is still a global problem in power industry;
