Transformer Conservator Isolation Valve (Tciv) is extensively used for isolating the electrical transformer conservator when an abnormal flow of oil takes place, due to bursting of transformer bushing or falling-out of transformer tank. It is not made to isolate the transformer conservator during the usual flow of oil. Transformer Conservator Isolation Valve (Tciv), offered by CTR Manufacturing Industries Private Limited is a padlocking arrangement and allows for erroneous use. This is a non-electrically operated product of modish technology. It can prevent the spread of fire and limits the spillage of oil from conservator.
