Abstract
The utility model relates to a self-supporting overhead insulated cable. The insulated cable comprises a group of conducting wire cores and a track rope, which are arranged and fixed parallelly; the group of conducting wire cores is formed by a plurality of intertwisted conducting wire cores; each conducting wire core is coated with a conductor shielding layer, an insulation layer, an insulation shielding layer, a metal tape shielding layer and a wire core jacket successively; and the track rope is provided with steel rope jacket. The insulation layer of the self-supporting overhead insulated cable is made of XLPE with good insulation. The metal shielding layer can realize the grounding design of shielding, which greatly increase the shielding capacity of cables. The jacket is made of whether resisting PVC material, thus having wide application scope. The track rope is also covered with the jacket, which increases the corrosion resistance of the cable steel rope. The track rope and the conducting wire cores are wound and fixed by plastic extruding steel rope, which further improves the safety of cables and extends the service life the cables.
Description
Technical field
The utility model belongs to technical field of electric wires and cables, particularly relates to a kind of self-bearing type aerial insulated cable.
Background technology
Along with urban construction constantly develops, many clumps of areas of tourism development zone and trees, the frequent generation of aerial condutor contacts with building, trees etc., takes place easily to get an electric shock and short circuit accident, and suspended insulated guide wire can effectively be avoided the generation of this type of accident.Suspended insulated guide wire often needs to be installed on the bearer cable, and corrosion phenomenon and thunderbolt take place the generally not insulation of existing bearer cable easily, and fire incident influences the fail safe that cable uses.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple and reasonable, safe self-bearing type aerial insulated cable, the antiseptic power of bearer cable and good insulation preformance in this cable, accidents such as thunderbolt and fire be can effectively prevent, fail safe and useful life that cable uses improved.
The technical scheme that provides according to the utility model: described self-bearing type aerial insulated cable comprises conductor wire core group and bearer cable, and conductor wire core group and bearer cable are arranged in parallel fixing; Described conductor wire core group is by many stranded the forming of conductor wire core, and every conductor wire core is coated with conductor shield, insulating barrier, insulation screen, metal tape screen and core sheath outward successively, and described bearer cable is extruded with the cable wire sheath.
As further improvement of the utility model, described conductor wire core adopts hard copper wire or hard-drawn aluminium wire.
As further improvement of the utility model, described bearer cable adopts galvanized vanized steel cable.
As further improvement of the utility model, described conductor shield and insulation screen all are to be that main material extrudes and forms by crosslinkable semiconduction material, and insulation screen has easy fissility.
As further improvement of the utility model, described insulating barrier adopts crosslinked polyethylene (XLPE) material to extrude and forms.
As further improvement of the utility model, described metal tape screen forms by the metal copper strips is wrapped.
As further improvement of the utility model, described core sheath and cable wire sheath extrude by weather resistant polyvinyl chloride (PVC) material and form.
As further improvement of the utility model, described conductor wire core group and bearer cable adopt the extrusion molding steel wire rope fixing around pricking.
As further improvement of the utility model, described conductor wire core is 3, and described bearer cable is 1.
The utility model compared with prior art, advantage is: insulating barrier adopts crosslinked polyethylene (XLPE) to make, and insulation effect is good.The ground connection design that metal screen layer can be realized shielding improves a lot the shielding properties of cable.Sheath adopts the polyvinyl chloride of anti-marquis (PVC) material to make, and is applied widely.Also be coated with sheath on the bearer cable, increased the resistance to corrosion of cable cable wire.Bearer cable and conductor wire core group adopt the extrusion molding steel wire rope fixing around pricking, the fail safe and the useful life of further having improved cable.
