This is a new druseidt product range which came about because of application problems. Since pneumatically activated contacts are mainly used with high current levels and heavier bus-bars, problems quite often occur in the quality of the current transfer especially with older systems or systems that run full time. The existing bus-bars are either damaged or bent in the area of contact after a certain amount of use. With the standard contact ranges this would cause the contact surfaces of the bus-bars to lie on just a portion of the contact area of the contact which leads to overheating in areas and contact problems. In order to solve these problems, especially on systems that run full time to reduce down times and system repairs, we have developed this new pneumatic contact range. Our new contact system, with its moveable contact fingers, adapts to the contact area even if the bar is bent or twisted up to 10 mm. All contacts have been equipped with a simple druseidt designed pneumatic construction. No complicated pneumatic cylinders or pneumatic cushions are required. The bus-bar slides in using its own momentum. This procedure causes a self-cleaning effect on the bar as it slides through the guides. The contacts require a minimum of maintenance and are very robust under heavy mechanical loads. The contact units are covered to the largest possible extent with extra stable stainless steel covers. The contact system is built modularly and can be adapted to the height as well as the width of systems having little extra space. The connection to the current supply system can either be made using the base plate or a connection side plate with massive copper. This contact system has proven itself in the transferral of high current loads. Systems with up to 40,000 A have been equipped with this contact system.
