Product Code  :   Air Cell
Product Name :   Air Cell
An Air cell is a sealed envelope made out of high resistant Polyamide fabric coated with synthetic elastomer. The air cell is fitted in the conservator of the transformer by means of two straps and a connecting flange. Due to its inflation and deflation the air cell breathes without permitting the outside air which causes degradation in contact with the expensive transformer oil thereby reducing its efficiency.                           
                                
Advantages  :    
                         
  • Eliminates oxidation and hydrolysis of oil due to air contact.
  • Offers excellent resistance to Oxygen, Ozone, Nitrogen and humidity.                         
  • Excellent impermeability to oil and gases.    
  • Long service life                           
  • Prevents any free volume in the conservator

The coating elastomer and fabric composite has been designed to meet the above requirements without affecting the oil quality.     
                                
Air cell dimensions are normally worked out based on the dimension of the Cylindrical Conservator
namely Diameter and the length of conservator.                               
                               
The Air cell has 3 principal dimensions. Length, Width and distance between loops/ strap.
