The utility model relates to a novel cable, including core conductor and insulating layer, insulation layer package is on the core conductor, it reaches the outer fire -retardant layer of protecting to protect the water blocking layer in the insulating layer periphery is equipped with, protect fire -retardant layer outward and protect the periphery of water blocking layer including setting up, beprovided with the foaming layer between core conductor and the insulating layer, the insulating layer outside is equipped with the shielding layer, the shielding layer outside is equipped with high temperature resistant layer, high temperature resistant layer with interior protecting is provided with the band layer between the water blocking layer, fill out between band layer and the core conductor and be equipped with a plurality of fibres that block water, the interior armor that is provided with between protecting the water blocking layer and protecting fire -retardant layer outward. The beneficial effects of the utility model are that: through the setting of foaming layer between core conductor and insulating layer, improved the protective properties of cable, strengthened the resistance to compression tensile ability of cable, prolonged the life of cable, the insulating layer outside is equipped with the shielding layer for the anti -interference can the reinforce, have high temperature resistant, block water, fire -retardant advantage.
