The on-load tap changer is suitable for power transformers or industrial transformers with a maximum operating voltage of 40.5kV, 72.5kV, 126kV, 170kV, and 220kV, and a maximum rated current of 300A, 500A, 600A for three-phase or 300A, 500A, 600A, 800A, 1200A, 1500A for single-phase. The rated frequency is 50Hz or 60Hz. The device is used to change the tap connection positions of the voltage regulating coil under load conditions to achieve voltage adjustment. It is suitable for Y-connected neutral point voltage regulation and single-phase voltage regulation at any point.
The ZM on-load tap changer is a modular on-load tap changer consisting of a switching mechanism and a tap selector. It features high breaking capacity, long contact life, high operational reliability, and a wide range of applications.
