Elastic transformer oil tanks (PER-N TM) with a capacity from 1 to 50 m3 or more are successfully used for draining and storing hot transformer oil (up to +85 °C) during scheduled and emergency repairs of substations and individual transformer sections, at linear substations and other power supply facilities.
PEER for transformer oil protection (PEER-ZMT) protects it from oxidation and humidification, which prolongs the service life of transformer oil at temperatures from -60 ° to +120 ° C.
