Syöttöjohto

Syöttöjohto, often translated as "feed line" or "feeder cable" in English, refers to a type of electrical cable used to transmit power from a source to a load. This can encompass a wide range of applications, from connecting a power station to a substation to supplying electricity to a building or an individual appliance. The primary function of a syöttöjohto is to carry electrical current efficiently and safely.

The design and specifications of a syöttöjohto are determined by factors such as the voltage, current carrying capacity, environmental conditions, and installation method. For high-voltage applications, such as those found in power transmission networks, syöttöjohto will be robust and insulated to withstand significant electrical stress. In contrast, lower-voltage syöttöjohto, like those used in household wiring, are typically smaller and less complex.

Materials commonly used in syöttöjohto include copper or aluminum for the conductors, chosen for their conductivity, and various insulating materials like PVC, rubber, or cross-linked polyethylene (XLPE) to prevent electrical leakage and ensure safety. The physical form of the syöttöjohto can vary, including single-core cables, multi-core cables, and overhead lines supported by poles or towers. Proper installation and maintenance of syöttöjohto are crucial for reliable power delivery and to prevent electrical hazards.
