| ZV on-load tap-changer applies to the power transformer or industrial transformer with rated voltage 35kV, 66kV, Max. rated through current three phase 350A, 500A, single phase 350A, 700A, frequency is 50Hz or 60Hz to change the tap position of voltage regulating coil under load for the aim of voltage regulating. |
| ZV on-load tap-changer is combined structure, combining the function of diverter switch and tap selector together to form selector switch, it bears the selection of taps and switching of load current, and form into integrated insert structure, the structure is impact, convenient in maintenance, reliable in work, applies to middle and small transformer. |
