Abstract
The invention discloses an anti-freezing pressure-resistant cable. The anti-freezing pressure-resistant cable comprises a conductor, an insulating layer, a heat conduction layer I, a heating layer, a heat conduction layer II, a shield layer and a sheath. The conductor is externally extruded by the insulating layer. The insulating layer is externally extruded by the heat conduction layer I. The heat conduction layer I is externally extruded by the heating layer. The heating layer is externally extruded by a heat conduction layer II. The heat conduction layer II is externally extruded by the shielding layer. The shielding layer is externally extruded by the sheath. The anti-freezing pressure-resistant cable is simple and reasonable in structure and is effective in freezing resistance.
