Cleaning paste for High-voltage insulators with silicone protection

Application: High-voltage Insulators' Cleaner is a perfect cleaning agent giving silicone protection for most high-voltage insulators. Enables easy and fast cleaning of the insulator's surface from pollution, getting efficient protective silicone film on its surface. It gained especially positive opinion after 3-year appliance on high-voltage switching stations in the most industrialized regions of southern Poland.

Characteristic: High-voltage Insulators' Cleaner is the product basing on long time experience. At most cases in order to get good cleaning effect it is enough just single cleaning of the high voltage insulator's surface from atmospheric impurities. Paste removes painting pollution remained after construction repair works.

Procedure: Cleaning process is very simple. Adhering dust is removed with a cloth from the insulator, which is rubbed off with High-voltage Insulators' Cleaner and polished using a dust cloth. Impurities, such as paint splashes etc. Can also be removed. At most cases a non-recurring treatment is sufficient in order to obtain clean and long-lasting protection from the remaining water and dirt repellent with Silicone-protective film. High-voltage Insulators Cleaner is free from faults as far as physiology is concerned. In areas of heavy fouling and humidity effects, after cleaning the insulator's surface should be additionally coated with High-voltage Insulators' Silicongreas in order to avoid spark discharge for a longer time.

Package: plastic comfortable tubes 0,75 kg, equipped with hanger.

Silicone paste for high-voltage insulators' protection

Application: Silicone paste High-voltage Insulators' Silicongreas creates hydrophobic protective film on the high voltage insulator's surface. It protects from erosion within the temperatures' range from -40^oC to +200^oC. In areas of heavy fouling, it is recommended to coat the insulator's surface with 300 mm thick film of High-voltage Insulators' Silicongreas .

Procedure: Paste should be applied on the insulator's surface by squeezing out from tube. Afterwards High-voltage Insulators' Silicongreas should be distributed using a dust cloth to demanded thickness and equality of film.

Characteristic: High-voltage Insulators' Silicongreas is a transparent, non-toxic substance, with ointment consistence. It is made on base of pure methyl silicate, with small amount, inorganic condensing agents. This product was produced on a long time experience basis. It characteristics is good spreading, which means ability to create a layer with constant thickness layer within a long time after appliance. High-voltage Insulators' Silicongreas does not change its consistence, within wide range temperatures from -40° C to +200° C, High-voltage Insulators' Silicongreas is a highly hydrophobic substance, insoluble even with hot steam. This paste is not metal, plastic, glass and ceramics aggressive.

Package: plastic comfortable tubes 0,75 kg, equipped with hanger. 

Examination and Attests

Examination of silicone pastes in Institute of Power Engineering

Pastes High-voltage Insulators' Cleaner and High-voltage Insulators' Silicongreas obtained certificate of specific technical proprieties allowing it to create a hydrophobic film on high voltage insulators.

Shortening from attest protocol Nr EWN/179/E/97 made in Institute of Power Engineering:

High-voltage Insulators' Silicongreas and High-voltage Insulators' Cleaner pastes were tested within the conditions of artificial rainfall 3 mm/min with water from water supply system at resistance 10 times lower than natural rain water. Total spraying time 100 h.

During the rain falling on a siliconized insulator rain, drops were beating back from the surface, and did not flow down with streams along the insulator. Partial discharges that took place during flashover voltage measurement, were smaller than for dirty insulator, and flashover itself was urgent and short and did not increase gradually.

Pastes during test (under rain gun) in Institute of Power Engineering

Long time rain spraying (100 h. water from water supply) of insulator did not remove silicone film, but distributed it all over the surface. Water on the floor under insulator did not show any colorful shades, which would indicate the paste's wash away. Measured withstand and flashover voltage were just insignificantly lower.

Details of measurement in accordance to PN-90/E-06308 standard are shown in the following table:
