Abstract
The utility model discloses a high-temperature resisting compensation special cable. The special cable is composed of main cable cores, a control cable core, a filling layer, an ethylene propylene rubber insulating layer, a copper tape shielding layer, a galvanized steel tape armored layer and a shielding sheath layer. Two groups of the main cable cores and a group of the control cable core are extruded in the filling layer, a copper wire current guide wire is further extruded in the filling layer, the ethylene propylene rubber insulating layer is wrapped outside the filling layer, and the copper tape shielding layer is wrapped outside the ethylene propylene rubber insulating layer. The special cable has the advantages of excellent conductivity, excellent aging resistance and strong wearing resistance, the special cable also has the advantages of heat resistance, high-temperature resistance and flame retardation, and the special cable can be widely applied to aerospace, electric power, metallurgy, tunnel and other fields.
Description
Technical field
The utility model belongs to field of cables, relates in particular to a kind of high temperature resistant compensation special cable.
Background technology
At present, along with Chinese society expanding economy, electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as aviation, electric power, metallurgy and tunnel, to the electric conductivity of cable and resistance to ag(e)ing, resistance to wear, the fire-retardant aspect of heat resisting and security reliability aspect require all high especially.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of fire-retardant high temperature resistant compensation special cable of good heat resisting that has.
The utility model takes following technical scheme to realize: a kind of high temperature resistant compensation special cable, it is comprised of master core, control core, packed layer, ethylene propylene rubber insulated layer, copper strip shielding layer, galvanized steel strip armour and shield sheath layer.Described packed layer inside is extruded with two groups of master cores and one group of control core, described packed layer inside is also extruded with a copper wire drainage thread, described packed layer is wrapped with the ethylene propylene rubber insulated layer of one deck, outside described ethylene propylene rubber insulated layer, is enclosed with one deck copper strips screen.
Described master core by copper conductor and the perfluoroethylene-propylene insulating barrier and the zinc-plated copper wire armour that are wrapped in successively outside copper conductor form.
Described ethylene propylene rubber insulated layer and copper strip shielding layer inside are all extruded with an aluminium conductor heating wire.
The utlity model has in sum following beneficial effect: the utlity model has good electric conductivity and resistance to ag(e)ing, resistance to wear is strong, also there is the fire-retardant characteristic of heat resisting, be widely used in the fields such as aviation, electric power, metallurgy and tunnel.
