Abstract
The utility model relates to a kind of all dielectric self-supporting cable, comprise that axial line parallels and the first oversheath be connected as a single entity and the second oversheath, described second overcoat has two, be positioned at the first overcoat above and below, and be connected with the first overcoat, described first oversheath comprises that oversheath, aramid fiber are wrapped, inner sheath, material water-proof material layer, Loose tube, the Loose tube at described center is steel-cored aluminium strand, filler between described material water-proof material layer and Loose tube is waterproof paste, contains the reinforced core of glass steel material in the second described oversheath.The utility model by adding the fiberglass reinforced core paralleled with traditional electrical cable, make cable aloft sandwiched time, no longer need the support cable added, reduce application cost, and fast easier for installation.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to a kind of all dielectric self-supporting cable.
Background technology
All dielectric self-supporting cable, refers to that cable self stiffener can bear deadweight and external load.Because be self-bearing type, so its mechanical strength is held the balance; Use all dielectric material to be because optical cable is in High Voltage electrical environment, must can tolerate the impact of forceful electric power; Owing to being built on stilts on electric force pole tower use, so supporting suspension member must be had to be fixed on shaft tower by optical cable.For the cable of aerial erection, generally need to arrange that the cable of supplemental support carrys out support cable separately, so just make the application cost of cable to strengthen, and install inconvenient.Self-supporting cable, because self stiffener of its cable can bear deadweight and external load, directly lays just passable so make messenger wire without steel strand wires in laying, therefore eliminates the built on stilts goods and materials such as hook, steel strand wires and save raw material, cost-saving.
Utility model content
For the problems referred to above, the utility model object is to provide a kind of all dielectric self-supporting cable.
The technical solution of the utility model is: a kind of all dielectric self-supporting cable, comprise that axial line parallels, and the first oversheath be connected as a single entity and the second oversheath, described second overcoat has two, be positioned at the first overcoat above and below, and be connected with the first overcoat, described first oversheath has multilayer to form, comprise oversheath, aramid fiber is wrapped, inner sheath, material water-proof material layer, Loose tube, described Loose tube contains eight, a Loose tube is positioned at center, all the other seven Loose tube are looped around center Loose tube surrounding, in described seven Loose tube, one of them Loose tube is filler, all the other six Loose tube are filled by some wires, filled by ointment between described wire, described center Loose tube is steel-cored aluminium strand, filler between described material water-proof material layer and Loose tube is waterproof paste, the reinforced core of glass steel material is contained in the second described oversheath, intensity and the toughness of cable can be strengthened.
Further, described first oversheath and the second oversheath are polyethylene or polyvinyl chloride material.
Further, the inner sheath in described first oversheath is polyvinyl chloride material.
Further, the connection between described first oversheath and two the second oversheaths is that fine rule connects.
Further, the firm material of the second overcoat glass be fibre-reinforced plastics, fibre reinforced composite plastic or boron fibre strengthen composite plastic any one, optimum fiber strengthen composite plastic.
Advantage of the present utility model is: this all dielectric self-supporting cable provided by the utility model, by adding the fiberglass reinforced core paralleled with traditional electrical cable, make cable aloft sandwiched time, no longer need the support cable added, reduce application cost, and fast easier for installation.The fiberglass reinforced core that the utility model is arranged on traditional electrical cable, improves the loop strength of cable, thus increases the service life of cable.
