Disk tap changer

No-excitation disk tap changer

1. Product introduction

   The immersed off-load tap changer is a device used for operating oil-immersed power transformers under the conditions of de-energization or off-load, to adjust the tap positions of the transformer coil and thereby alter the transformer ratio.
