Abstract
The utility model discloses an environment-friendly type crosslinking polyethylene insulating, water-resistant, flame-retardant and shielding power cable which comprises, from inside to outside in turn, a conductor, a conductor water-resistant layer, a conductor shielding layer, an insulating layer, an insulating shielding layer, a phase-splitting metal shielding layer, a cable core water-resistant layer, a packaging metal shielding layer, a water-resistant isolation layer, a metal armor layer and an external protective layer. The conductor, the insulating layer and the cable core of the cable all have a water-resistant function. An excellent water tree resistant insulating layer can reduce a phenomenon of water tree discharging so that the service life of the cable can be enhanced from 30 years to 50 years. Dual shielding of the cable ensures effects of electric field uniformity, shielding, anti-interference, anti-magnetism of the cable and safe operation of the cable. The armor layer and the environment-friendly type external protective layer ensure low toxicity and flame retardance of the cable.
