Silicon rubber insulation power cable

The invention discloses a silicon rubber insulation power cable. The power cable comprises a conductor, an insulating layer, a shielding layer and a sheath layer, wherein the insulating layer is arranged outside the conductor, the shielding layer is arranged outside the insulating layer, and the sheath layer is arranged outside the shielding layer. The insulating layer is made of silicon rubber, and the silicon rubber is prepared from vinyl-terminated methyl vinyl silicon crude rubber, methyl vinyl phenyl silicon crude rubber, poly(propylene glycol maleate), dicumyl peroxide, active magnesium oxide, vinyl benzene, Vaseline, vinyl-terminated silicone oil, oxidized polyethylene wax, white carbon black, emery powder, calcium carbonate, blanc fixe, calcium/zinc stabilizer, argil, modified hollow glass beads, silane coupling agent KH-792, antiager 264 and antiager 4010NA. The silicon rubber insulation power cable is excellent in ageing-resistant performance and mechanical property.
