Power engineering application example: Relaxed working - even at 38,500 volts.

A medium-voltage network with up to 38,500 volts and 12,000 A is used to distribute electrical energy for several towns, individual districts or railroads. If the power supply is to be interrupted - for example for repairs - special switchgear is required to protect people in the electrical environment.

Fritz Driescher KG from Wegberg manufactures such switching devices - driven by SPN spur gearboxes. Important criteria here are high reliability and robustness, so that the function is guaranteed even in extreme heat or cold and after long downtimes. In the event of a power failure, this process can also be carried out manually - using an attachable hand crank. In this case, the electronic drive is mechanically decoupled beforehand. Safe is safe.
