Abstract
A cable insulated with a cross-linked polyethylene layer is described, wherein the cross-linked polyethylene is prepared by cross-linking with 2,5-dimethyl-2-5-di(tert-butylperoxy)hexane or 2,5-dimethyl-2,5-di(tert-butylperoxy)hexyne-3 as a cross-linking agent. Even if voltage is applied at high temperatures, the breakdown voltage of the cable can be maintained at a high level.
