RTV Anti pollution flashover coating gor Outdoor Insulators



Product characteristics

  1. Excellent hydrophobicity and quick, balanced and lasting hydrophobic migration property. Continuous water film will not be formed even in atrocious weather (rainy, foggy, dewy, or drizzly).
  2. High anti pollution flashover voltage, anti electric arc, tracking resistance, excellent electrical insulation;
  3. High strength; high adhesion; acid, alkali and salt resistance; corrosion resistance to strong oxidizer;
  4. Ozone resistance, UV rays resistance, resistance to environmental aging; non peeling, non cracking
  5. Formed inplace; convenient to use; meeting the needs of anti pollution technology and measures for power transmission and transformation equipment fields;
  6. Long effective operation time; easy to maintain; free cleaning during the period of validity; high efficiency.

Implementation standard


National Grid Construction and Operation[2006]1022 National Grid Company Cross-region Grid’s Guidelines on the Anti pollution Flashover Coating Application for External Insulation on Power Transmission Equipment (Trial Implementation) DL/T627 Room Temperature Cured Silicone Rubber Anti pollution Flashover Coating For Insulators.


Range of application


Products are mainly used in power system, substation and transmission line insulator, power plants and substation equipment and other electrical equipment insulation lasting antifouling flash. Applicable to the environmental temperature to subzero 50 degrees Celsius to 100 degrees Celsius, all kinds of voltage grade, ac and dc system under the condition of filth operation of transformer substation and external insulation antifouling pedestal transmission line equipment. To prevent flashover, improve equipment insulation level.

Products are widely used in metallurgy, cement, chemical, mining and salt fog and other pollution environment, also are used in the 500 kv and above system showed superior antifouling performance, guarantee the safety of power grid.


Methods of Application


We suggested that on the condition of power cut by a construction personnel who has professional construction qualification to coating this product.

Before construction, the surface of the insulator should be cleaned, they can’t have dust, grease, etc., and make sure the surface drying

Choose spraying or brush coating methods for construction, the construction shall be carried out under the good weather.

Coating thickness may between 0.3 to 0.6 mm, coating should be complete, no defects, and avoiding leakage.

After coating 45 minutes, the surface will be dry, when the thickness does not meet the construction requirements, it can spray and brush again after the surface dried. Fully cured 24 to 48 hours.


Storage and transportation


  1. Product packaging in a sealed metal container, need to keep in dark, avoid heat and ventilation, dry environment.
  2. Shipment should be kept in dry and ventilated, prevent the sun and the rain, transport according to the non-dangerous goods.
