Abstract
The utility model discloses an insulating power cable which is characterized in that metal conductors are extruded with crosslinked polyethylene insulating layers to form insulating wire cores, and three insulating wire cores are twisted to form a cable and then the cable is extruded with a wrapping strip layer. A cable core is filled with hemp ropes. The wrapping strip layer is extruded with an inside liner which is coated a double galvanized steel strip armoring layer. The armoring layer is extruded with a polyvinyl chloride outer sheath layer or a polythene outer sheath layer. The structure of the cable is simple, and a sheath uses the polyvinyl chloride outer sheath or the polythene outer sheath, so the cable is advantaged by excellent flame retardation, high mechanical strength, etc. The cable can effectively prevent combustion of flames, and fireproof performance of the cable is improved and service life of the cable is prolonged.
Description
Technical field
The utility model belongs to the electric wire field, is specifically related to a kind of insulated power cable.
Background technology
Along with socioeconomic development, the electric wire consumption increases rapidly, the electrical fire accident also occurs again and again, people are from the heaviness lesson of electrical fire accident, recognize gradually at some important places, such as electric equipments in the circuits such as naval vessel, production platform, petroleum chemical enterprise, large-scale power station, large-scale command and control center and skyscraper, underground structure, tunnel, subway, it is very important keeping being in stable running status in the certain hour under fire condition.
The utility model content
The utility model purpose provides a kind of simple in structure, insulated power cable of having good insulation property and can moving continuously in thermal-flame.
Scheme of the present utility model is as follows: a kind of insulated power cable, it is characterized in that metallic conductor extrudes the XLPE insulating barrier outward and consists of the insulation insulated wire cores, extrude belting layer behind the three eradication edge core twisted synthesizing cables, fill with the rope made of hemp at the cable core place, described belting layer extrudes inner covering outward, the two galvanized steel strip armours of described inner covering outer cladding, described armour extrudes polyvinyl chloride or polyethylene external sheath layer outward.
Described metallic conductor is copper conductor or aluminium conductor.
Described belting layer is the polyethylene band.
The utility model construction of cable is simple, and sheath adopts polyvinyl chloride or polyethylene oversheath, has well the advantages such as fire-retardant, high mechanical properties, can effectively prevent the burning of flame, improves the fireproofing of cable performance, prolongs cable useful life.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
A kind of insulated power cable, the metallic conductor 1 outer XLPE insulating barrier 2 that extrudes consists of the insulation insulated wire cores, extrude belting layer 3 behind the three eradication edge core twisted synthesizing cables, fill with the rope made of hemp 4 at the cable core place, the described belting layer 3 outer inner coverings 5 that extrude, the two galvanized steel strip armours 6 of described inner covering 5 outer claddings, described armour 6 outer polyvinyl chloride or the polyethylene external sheath layers 7 of extruding.
In the implementation, described metallic conductor 1 is copper conductor or aluminium conductor, and described belting layer 3 is the polyethylene band.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and modification; when its function that produces does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
