ABSTRACT:
An energy conducting cable loop enclosure which receives and retains an above-ground loop of a flexible conductor cable in an underground energy distribution system, particularly in a system for the supplying of electrical energy. The main body structure, which is upright in normal placement, is of elongate rectangular shape with an above-ground and a below-ground portion and having an open bottom and a closed top. At the junction of these two portions, supporting feet are located which bridge a hole in the ground, in which the below-ground portion is inserted, to rest on the surrounding ground. A removable front plate provides access to the interior of the above-ground portion. The above-ground portion contains a cable hoop having a radius at least as great as the minimum allowable bending radius of the cable on which a loop of cable is trained after being led through the open bottom and out through the open above-ground front. The depth of the hoop is substantially equal to the depth of the body structure so that the cable loop is captured on the hoop when the front plate is secured in place. The structure is held in place by the anchoring effect of the buried cable by way of the captured cable loop. The dimensional interaction of the structural elements combine for the provision of cable loops of desired size for interfacing with system components. Means are provided to prevent unauthorized removal of the plate.
