Product description
Introduced in CAPT’s products portfolio only a decade ago, 099 series has immediately reached great success thanks to the extreme flexibility of installation that is achieved through the cable system. Not only the tap changer can be installed horizontally on the top part of the transformer with contacts towards front, or in front of the windings, but it can be also mounted with different orientations, in example horizontally with contacts turned towards ground. It can be even mounted vertically on the side of the transformer, which allows to save space on the top and reduce the overall dimensions of the machine.
The cable itself is made of an internal body of steel passing through a plastic sheat, which is protected by a steel tubular pipe. This solution is usually provided as a single element already assembled, with a total diameter of 4,5 mm: customer will receive a single cable to be easily cut-to-size. As an alternative, the two main components of the cable system can be purchased as distinct items: the plastic sheath with its inner steel cable will represent one unit, the steel tubular pipe will come separately. In this specific case, customer will need to assembly them on site and the total diameter will be 7 mm.
The possibility to place the drive at several levels thanks to the cable system makes this series extremely efficient and flexible for every application.
