Product Description
The CDF2 on-load tap changer motor-drive unit is mainly used as a mechanism to drive and control the tap changer action, so that the tap changer switches from one tap position to another, thus achieving voltage regulation.
The mechanical and electrical components required to operate the on-load tap changer are installed in the motor drive unit and electrical interlocking circuits are used.
Generally, the motor-drive unit is supplied as an accessory to the on-load tap changer unit as a complete set.
