Innovative high-current contact solution

Online Editor

At numerous points in switchgears, transformers, circuit breakers, isolator switches and feedthroughs, we find detachable connections and connectors in which contact elements are used. These elements must transfer extremely high currents, particularly in the event of short-circuits. In the process, they should not only offer flexibility for compensation of dimensional tolerances, but also a reliable connection even after countless mating cycles. Multilam, the novel contact louver technology from Stäubli, offers confidence and reliability for solving this problem. The new ML-CUX from the Multilam flexo line will be of great interest to the power sector.

The new solution is the result of consistent development of the two-component principle. The separation between the electrical and mechanical properties results in a constant low contact resistance and minimal contact heating, even with constant high load. Furthermore, the ML-CUX is able to withstand extreme current peaks and has a short-circuit current-carrying capacity of up to 4.4kA/cm. This allows a significantly more compact design, so the connectors can be implemented more easily even in smaller systems.

A simple, low-depth rectangular slot is sufficient for the installation; this allows slimmer designs than coil spring contacts but still guarantees a reliable hold in the plug and socket.

In the area of energy supply and distribution, components from different origins are installed together. Those responsible are often faced with mechanical problems and have to reckon with large dimensional tolerances, offsets and angular deviations. The Multilam Flexo ML-CUX meets these challenges: thanks to its large working area, it is highly flexible and able to compensate angular and axial offsets.
