The TCM 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. This barrier also reduces condensation and oxidation inside the transformer and suppresses gas bubble formation in the transformer oil.\u003c\/p\u003e\n\u003cp\u003eSEI custom fabricates each TCM Air-Cell, also called a transformer conservator bladder, to be used inside cylindrical, elliptical, octagonal or rectangular-shaped conservator tanks. The TCM Air-Cell floats in oil inside the conservator and expands\/contracts by breathing through a flange placed in a customer-specified location, thus allowing the TCM Air-Cell to compensate for oil displacement due to temperature variations in the transformer.\u003c\/p\u003e\n\u003cp\u003eSEI specializes in quick delivery for custom TCM Air-Cells to meet the demands of field service operators. When required, SEI can engineer and manufacture a new Air-Cell in as little as 24 hours from an approved drawing or damaged tank. All SEI TCM Air Cells enable sealed conservator insulating liquid preservation systems to meet IEEE Std C57.12.00-2010 6.6.2.\u003c\/p\u003e\n\u003ch5 class=\"wp-block-heading\"\u003e\u003cstrong\u003eComparison Chart\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cfigure class=\"wp-block-table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth scope=\"col\"\u003e\u003cstrong\u003eFabric Conservator Air-Cell\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth scope=\"col\"\u003e\u003cstrong\u003eOil-Filled, Inert Gas Preservation\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLower annual maintenance\u003c\/td\u003e\n\u003ctd\u003eSystem must be monitored more closely.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLower operational costs.\u003c\/td\u003e\n\u003ctd\u003eSystem must be topped up each year.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMore reliable for remote or unmanned locations.\u003c\/td\u003e\n\u003ctd\u003eIf no monitoring, must be manually inspected.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBetter operational temperature ranges\u003c\/td\u003e\n\u003ctd\u003eMore temperature sensitive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFungicide can be added\u003c\/td\u003e\n\u003ctd\u003eNo need for fungicide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMore labor intensive to install\u003c\/td\u003e\n\u003ctd\u003eUsually comes fully assembled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLess likelihood of oil contamination\u003c\/td\u003e\n\u003ctd\u003eHigher likelihood of oil contamination\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch2 class=\"wp-block-heading\"\u003e\u003cstrong\u003eCustom Construction\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eTCM Air-Cells are constructed from Temp-Shield™ 30 oz. (1017 g) urethane elastomer-coated nylon fabric that has been specifically designed to be compatible with transformer oils, silicon fluids and bio-degradable transformer oils.
