Main Technical Data
      ZM on-load tap-changer applies to the power transformer or industrial transformer with rated voltage 35kV, 66kV, 110kV, 220kV, Max. rated through current three phase 300A, 500A, 600A, single phase 300A, 500A, 600A, 800A, 1200A, 1500A, frequency is 50Hz or 60Hz to change the tap position of voltage regulating coil under load for the aim of voltage regulating. Among them three phase Y connection tap-changer is used for the Y connection neutral point voltage regulating, single phase tap-changer can be used for the random voltage regulating.
      ZM on-load tap-changer is combined type on-load tap-changer, and composed of diverter switch and tap selector, its breaking capacity is big, contact service life is long, the operation reliability is high, applicable to a wide range and so on characteristics, especially the multi-step liner regulating and coarse and fine regulating applies to the industrial transformer with wide voltage regulating scope in metallurgy and chemical industry.
