Air/Oil Cooled Transformer Rectifier

KT series transformer rectifier is a kind of automatic controlled transformer, used as the DC power for impressed current cathodic protection, manufactured according to IEC146 standard.

With the advantages of stable operation, high efficient, energy-saving, light weight, no noise, lighting protection, the equipment is widely used in the long pipeline, tank interior bottom and other buried and submerged steel instruction.
