ABSTRACT:
Potential hot spots, such as at joints, in buried power cable runs are cooled by juxtaposing coolant flow conduits adjacent the cable and providing thermally conductive bridging members between the conduits and the cable throughout the potential hot spots to provide local cooling directly at the hot spots. The bridging members are cast metal clamps with portions to attach to lugs formed on the metallic cable sheath at the hot spots and portions which embrace the cooling conduits. Copper strips are provided underlying the clamps and embracing the cable and the cooling conduits to enhance thermal transfer from the cable to the coolant, and, with the coolant conduits formed of copper pipe, electrical insulators are provided in the metallic cable sheath so as to define an electrically isolated section in the region of the potential hot spot which can be coupled thermally and electrically directly to the coolant conduits.
