Overview The Air Cell (Flexible Separator) is fitted inside a conservator tank, isolating insulating oil from the atmosphere, and thus preventing contamination of gas and/or moisture from coming in to contact with the transformer oil due to oxidation and hydrolysis. The bag is vented o the transformer through flange type mounting such that it inflates or deflates to accommodate oil volume displacements due to changes in the transformer temperature. The Air Cells are manufactured using time tested combination of Nylon (Polyamide) fabric and thick coating of Elastomers i.e. Acrylonitrile...

The Technology The product design and construction of Zena-Cell® is based on thorough analysis of the stringent and diverse environments in which they have to perform. Their constitution takes into account the various factors that affect the performance over long periods of operation. The Air Cell we manufacture incorporates the latest coating technology. Some of the most important features that make Zenith’s Air Cell exclusive are: The Polyamide Substrate: The textile reinforced supporting fabric is made from high tenacity Nylon yarns and designed specifically for flexible Separators. The...

The Quality World class quality and the well-evolved rubber technology at our command is underscored by an ISO 9001 Certification and ISO 14001certification covering all major criteria i.e. Design, Development and Production. This reassures our clientele a consistent quality and on-time deliveries. Each air cell endures a four day test procedure where it is checked, rechecked and double checked for leakages under pressure and proper performance leaving no doubt in our customer’s mind regarding the dependability of the product. Routine Tests Type Tests Basic Fabric: 1. Visual Inspection for...

Installation Of The Zena Cell Step Push the Air Cell into the conservator through the open end or inspection hatch in the end of the conservator. Suspend the Air Cell from hooks (2) in the ceiling of the conservator using the loops. Fit the Air Cell flange (8) on the conservator flange using a ring (7) to ensure air tightness of the system. Close the open end of the conservator. Fill the Air Cell to a pressure of 10kPa (0, 1 bar). Close the filling valve (3) while leaving the system pressurized. A relief hole (4) must be on the oil filled side of the conservator so that the Air Cell can...

Filling The Conservator Step The pressure of air in the aircell should be 10kPa (0, 1 bar). If not, increase the pressure to the correct level and close the air-filling valve. Check the air vent valves (4) are open at both ends of the conservator. Open the valve (6) between the conservator and transformer tank and pump in more oil so that the oil rises to the conservator. The pumping speed should be suitably slow so that the pressure within the Air Cell does not exceed 13 kPa (0, 13 bar). Stop pumping, when oil begins to come out of the vent valves and close the vent screws. Regulate the...
