Abstract
PURPOSE: To promote an improvement of the electrical characteristic with a generation prevented of a protruding portion of unevenness, by constructing the semiconductive layer with an admixture made from between polyolefine or rubber and a prescribed conductive carbon black.
CONSTITUTION: A construction of the power cable comprises a conductor 1, an inner semiconductive layer 2, an insulating layer 3, outer semiconductive layer 4, a shielding layer 5 and a sheath 6. The semiconductive layers 2, 4 of the power cable are constructed by the below described admixture. The construction of the admixture is made between polyolefine (for instance, polyethylene, EVA, EEA, etc.) or rubber (for instance, EPR, EPPM, butyl rubber, etc.) and conductive carbon black, with less than 0.1% of ash further with less than 0.01% of screen residue measured by a conformity of JISK6220. And for constructing the semiconductive layer, it is preferable to operate an extrusion forming simultaneously with the insulating layer. And any of publicly known antioxidant and bridging agent may be added.
