Abstract
The utility model discloses a kind of reinforcement type water-proof cable, comprising: cable core triangular in shape, extrude block water belting layer and separation sleeve successively outward at cable core, extrude oversheath at cable core outermost layer; Described cable core is combined by an insulated wire cores, two reinforced cores and triangle fixture; Described two are connected to each other by the reinforcement with supporting role between strengthening core and insulated wire cores.The water repellent electric cable of the utility model design, cable core is by adding fixture, and structure is more stable, is not easily extruded distortion, fracture, ensure that the conductivity of cable, long service life; In addition, the structural design of this cable, is provided with water blocking layer, fills some material water-proof materials, add the block-water performance of cable, thus add the insulating properties of cable, through-put power; Also can not cause blast because of aging, add fail safe.In addition, be provided with reinforced in this cable, more firm and stable to the overall structure of cable.
Description
Technical field
The utility model relates to electric wire field, specifically refers to a kind of reinforcement type water-proof cable.
Background technology
China's most area belongs to temperate climate, and rainfall snowfall is many, and groundwater resources enrich, and cable is generally laid on underground, requires higher to protection against the tide.In order to improve the water preventing ability of cable, people take to apply material water-proof material outward at the cable core of cable usually, composition water repellent electric cable.But material water-proof material is relative to common insulating material, thermal resistance is relatively large, seriously hinders the proper heat reduction of cable, thus causes electric cable heating amount to increase.Increasing of electric cable heating amount, can cause the reduction of cable transmission power on the one hand; Core can be made on the other hand to insulate accelerated ageing of being heated.After ageing of insulation, block-water performance reduces, and moisture enters insulation and then enters cable joint along insulation longitudinal flow, thus cable may be caused to blast.
In addition, the cable conductor structure of prior art is easily extruded distortion, even ruptures, and have impact on conductivity and the useful life of cable.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of product processing technique is simple, water preventing ability good, production cost is low, the reinforcement type water repellent electric cable of Stability Analysis of Structures, long service life.
A kind of reinforcement type water-proof cable described in the utility model, comprising: cable core triangular in shape, extrudes block water belting layer and separation sleeve successively outward at cable core, extrude oversheath at cable core outermost layer; Described cable core is combined by an insulated wire cores, two reinforced cores and triangle fixture; Described two are connected to each other by the reinforcement with supporting role between strengthening core and insulated wire cores.
Further improvement, described insulated wire cores is made up of conductor and conductor water blocking layer, insulating barrier, insulation screen and the armour be coated on successively outside conductor.
Further improvement, described strengthening core is by steel wire rope and be extruded in waterstop outside steel wire rope, screen forms.
Further improvement, described cable core gap is provided with water blocking yarn packed layer.
Further improvement, outside described cable core and the gap blocked water between belting layer is provided with filled and process layer.
The beneficial effects of the utility model are:
Compared with prior art, the water repellent electric cable of the utility model design, cable core is by adding fixture, and structure is more stable, is not easily extruded distortion, fracture, ensure that the conductivity of cable, long service life; In addition, the structural design of this cable, is provided with water blocking layer, fills some material water-proof materials, add the block-water performance of cable, thus add the insulating properties of cable, through-put power; Also can not cause blast because of aging, add fail safe.In addition, be provided with reinforced in this cable, more firm and stable to the overall structure of cable; The improvement of above aspect, substantially increases product serviceability and the performance of enterprises.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
embodiment:
As shown in Figure 1, a kind of reinforcement type water-proof cable described in the utility model, comprising: cable core triangular in shape, extrudes block water belting layer 12 and separation sleeve 13 outward successively, extrude oversheath 14 at cable core outermost layer at cable core; Described cable core is combined by an insulated wire cores, two reinforced cores and triangle fixture 10; Described two are connected to each other by the reinforcement 9 with supporting role between strengthening core and insulated wire cores; Described cable core gap is provided with water blocking yarn packed layer 15.Outside described cable core and the gap blocked water between belting layer 12 is provided with filled and process layer 16.
Described insulated wire cores is made up of conductor 1 and conductor water blocking layer 2, insulating barrier 3, insulation screen 4 and the armour 5 be coated on successively outside conductor 1.
Described strengthening core is made up of steel wire rope 6 and the waterstop 7 be extruded in outside steel wire rope 6 and screen 8.
The utility model provides a kind of reinforcement type water-proof cable version and implementation method; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
