Wall connection (electrical installation)

from Wikipedia, the free encyclopedia

A wall outlet is an electrical outlet attached to the wall of a building. The connection can either be made via an aerial cable or an overhead line . In the case of an overhead line connection, insulators must be attached to the wall. The overhead line is tensioned to these and the line either runs as an insulated cable through a downwardly sloping pipe or, in the case of wall connections for high voltage, through a bushing insulator into the building. Wall connections for low-voltage and telephone lines used to be widespread for supplying houses, but for safety reasons they are now almost only used in buildings that are used for power supply , such as B. to find transformer houses. Wall connections for high voltage can be found on transformer stations with overhead line connections in buildings , on converter halls of HVDC stations and on voting houses with self-radiating transmission masts for feeding the same.
