Product Description

ZM on load tap changer

General
The ZM on-load tap-changer is suitable for the highest working voltage 40.5kV, 72.5kV, 126kV, 170kV, 220kV,
the maximum rated through current three-phase 300A, 500A, 600A, single-phase 300A, 500A, 600A, 800A, 1200A,
1500A, rated The power transformer or industrial transformer with a frequency of 50Hz or 60Hz changes the tap
connection position of the voltage regulating coil under load to achieve the purpose of voltage regulation. Suitable for
Y-connection neutral point voltage regulation, single-phase voltage regulation at any position.
The ZM on-load tap-changer is a combined on-load tap-changer, which is composed of a diverter switch and a tap
selector. It has the characteristics of large breaking capacity, long contact life, high working reliability, and wide
application range, especially many Level linear adjustment and multi-level coarse and fine adjustment are suitable for
industrial transformers that require a wide range of voltage adjustment in metallurgy and chemical industries.
