Flexible Separators (Air Cells) manufacturers using time tested combination of Nylon (Polyamide) Fabrics and thick coating of Elastomers I.e. Acrylonitrile Butadiene Rubber (NBR) , Polychloroprene (CR) and Hypalon (CSM).
AIRCELL used as constant oil preservation system in transformer and reactors. It is fitted inside a conservator tank isolating the transformer insulating oil from the atmosphere, thus preventing contamination, gas and / or moisture from coming into contact with the transformer oil.
Air-cell acts as a barrier to separate undesirable elements in the atmosphere, such as water vapor, nitrogen, ozone and oxygen, from transformer oil within a conservator.
Advantages of Air-Cell
- Simple design with no expandable parts.
- Needs negligible man hours for inspection.
- Extended service life.
- Economical.
- Prevents corrosion.
- Oil can be filled into the transformer tank without being exposed to the air
- Since insulating oil is completely isolated from the atmosphere by an air cell, there is no possibility of oxygen or moisture penetrating the oil.
- Pressure on the surface of the oil is constantly maintained at the atmospheric pressure, offering no possibility of the oil becoming supersaturated and forming bubbles; thus, high dielectric strength can be maintained.
