Application Scope and Application Method of RTV Silicone Coating for Insulator

RTV silicone coating for insulator is based on organic silicone rubber and is prepared under clean, dry and oxygen isolation conditions using new technologies and processes such as W. Hassen theory, Interpenetrating Point Network (IPN) technology and migratory catalase. The product has the following significant features:

  1. Outstanding hydrophobicity and fast, balanced, sustained hydrophobic migration;

  2. High pollution flashover voltage, arc-resistance, resistance to electric leakage and scratching, superior electrical insulation;

  3. High modulus, high strength, high adhesion, high corrosion resistance, meeting the requirements for regular maintenance and overhaul;

  4. Resistance to ozone, ultraviolet radiation, environmental ageing. No peeling, no cracking;

  5. Long effective running time, simple maintenance, no cleaning during the validity period, high efficiency;

  6. Single-component room temperature curing, simple to use.

1. Application scope of RTV silicone coating for insulator

RTV silicone coating for insulator is suitable for use in AC and DC systems where the nominal voltage is higher than 1kV and under dirty conditions. It is mainly used in power system substations, transmission and distribution line insulators and power plant booster stations, as well as chemical, steel, electrified railways, mines and all dirty, foggy and humid environments, to improve the external insulation level of equipment and prevent flashover accidents.

2. Application method of RTV silicone coating for insulator

It is recommended to apply RTV insulator silicone coating under power outage at -30℃~+50℃ by qualified professionals. If the paint is not used up once, it should be covered tightly and kept closed for the next time.
