Kuljettijärjestelmän

Kuljettijärjestelmän, known in English as the driver system or conductor system, refers to the electrical components that provide power to a moving electrical appliance or vehicle. In its simplest form, it consists of a conductor, often a rail or wire, that carries the electrical current, and a contact shoe or trolley pole that picks up the current from the conductor. This allows for a continuous supply of power to the device as it moves along its path.

These systems are commonly found in electric trains, trams, and trolleybuses, where they enable the vehicle to draw electricity from an overhead line or a third rail. The conductor provides a safe and reliable way to deliver high-voltage power without the need for heavy onboard batteries or the limitations of cables. The design of the kuljettijärjestelmän is crucial for efficient energy transfer and operational safety, with considerations for insulation, current collection efficiency, and protection against environmental factors. Variations exist depending on the application, including overhead catenary systems and ground-level conductor rails. The development of kuljettijärjestelmän has been fundamental to the electrification of public transport and industrial machinery, contributing significantly to reduced emissions and improved operational capabilities.
