Abstract
PURPOSE:To increase the dielectric strength by providing space charge mitigating layers copolymerized with ethylene and aromatic monomer at least either between an inside semiconductive layer and an insulator or between an outside semiconductive layer and the insulator. CONSTITUTION:Space charge mitigating layers 4-7 preventing the accumulation of space charges are provided at least either between an inside semiconductive layer 1 located around a conductor M and an insulator 2 or between an outside semiconductive layer 3 and the insulator 2. The space charge mitigating layers 4-7 are formed by copolymerization at the ratio of aromatic monomer 0.01-2mol% against ethylene 1mol. the electron energy on the periphery is sucked by the resonance effect of the benzene ring of the aromatic monomer, the formation of space charges is prevented, in addition the dielectric strength of the base polymer constituting the resin is improved. The DC breakdown voltage of a cable can be thereby increased.
