Description
The tank is hermetically sealed and completely filled, with ONAN cooling, so the oil does not contact the air and needs no conservator. Mineral oil to IEC 60296 is used. Complies with EN 50588-1 and EN 60076-1, with Ecodesign 548/2014 losses in classes A0Ak, A0Bk and A0Ck. Pole-mounted units go on overhead line poles, ground-mounted ones in packaged substations.
