Product Description

ZV on load tap changer applies to the Power transformer or industrial transformer with rated voltage *5kV, *6KV, Max. rated through currentg three phase **0A, **0A, single phase **0A, **0A, frequuency is *0Hz or *0Hz to change the tap postion of voltage regulating coil under load for the aim of votlage regulating. ZV on-load tap changer is combined structure, combing the function of diverter swtich and tap selector together to form selector swith, it beats the selection of taps and switch of load current, and form into integrated insert structure, the structure is impact, convenient in mantenane, reliable in work, applies to middle and small transformer.
