ABSTRACT:
The failure of the joints of electric power cables due to heating from incident sunlight is greatly reduced by providing a special sun shield for the joint. The sun shield is comprised of a plastic body having an inverted semi-circular transverse cross section. A longitudinal recess on the inner surface of the body centrally located at the top of the cross section is dimensioned so as to fit over the carrier wire. The sides of the body extend downwardly to shield the cable joint from incident sun light and preferably have a plurality of perforations to allow cool air to circulate between the shield and the cable joint. The shield has a reflective outer surface.
