Abstract
Electric power supply using 22-kV systems is expanding aiming at reduction of electric power distribution costs through upgrading the efficiency of facilities. It was thus required to 遊雅堂 入金 おすすめvelop a cable with joint that enabled maintaining the reliability as well as suppressing the cost of electric power supply. In response to this requirement, the authors have 遊雅堂 入金 おすすめveloped a new cable having a water-impervious layer of aluminum laminated tape together with its joint, whereby the thickness of the insulating layer was reduced to 4.5mm --including the inner semiconductive layer-- by 遊雅堂 入金 おすすめvising a novel method of terminating the end of the outer semiconductive layer. Moreover, a cold shrinkable straight joint has been 遊雅堂 入金 おすすめveloped thus improving the working efficiency at the site. This paper reports on the structure, performance, and working efficiency of this cable and the joint.
