Abstract
A switching apparatus adapted to be used with medium-voltage cable networks comprising switching units each of which is of the single-pole type and each of which includes an encapsulation adapted to be embedded directly in the soil and means for actuating the unit in response to a remote control. The switching apparatus is particularly suited for medium-voltage cable networks in cities where the erection of above-ground distribution facilities is undesirable and expensive. The switching units may, preferably, be designed as vacuum circuit breakers.
