Kiskojärjestelmin

Kiskojärjestelmin is a Finnish term that translates to "guide rail system" or "conductor rail system." It refers to a type of electrical power supply system used primarily in industrial settings, workshops, and some public transportation systems. The core concept involves a conductive rail, typically made of metal, that carries electrical current. Movable current collectors, often called "shoes" or "trolleys," slide along this rail, picking up the electricity needed to power a piece of equipment.

These systems are commonly found on overhead cranes, electric hoists, and monorails, where they provide a continuous and mobile source of power. In some older or specialized tramway and subway systems, conductor rails have also been used as an alternative to overhead catenary lines. The advantage of a kiskojärjestelmin lies in its ability to supply power to moving machinery without the need for trailing cables, which can be cumbersome, prone to wear, and pose a safety hazard. The design typically involves insulated support structures for the conductor rail and safety features to prevent accidental contact. Maintenance of the system is crucial to ensure reliable operation and to prevent electrical faults.
