YSF20-50T,80T,125T Series Pressure Relief Device

YSF20-50T,80T,125T Series Pressure Relief Device

YSF20-50T,80T,125T is mainly suitable for pressure relief inside the oil tank of large oil immersed power transformers, power capacitors, reactors and other equipment when the pressure exceeds the limit. In addition to the conventional electrical alarm signal, a computer electrical alarm signal function can also be added to achieve dual electrical signal output, and each can be independently led out. Users can choose according to their needs when ordering products.
