Abstract
The utility model provides a moving metallic-shield monitoring type rubber-sleeve soft cable for a coal mine, and the cable comprises three power cable cores which are arranged in a triangular shape. Each power cable core is sequentially wrapped by a power cable core conductor, a conductor shielding layer, an insulating layer, and an insulating and shielding layer from the inside to the outside. The three power cable cores are sequentially wrapped by a cabling taped-covering layer, an inner sheath, a monitoring layer, an insulating taped-covering layer, and an outer sheath. Filling materials are filled between the power cable cores and the cabling taped-covering layer. The inner and outer sheaths are respectively formed by the extruding of ethylene-octene mixtures. The cable provided by the utility model is environment-friendly, is low in cost, is high in weather resistance, and the like.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of moving metal shield monitor type rubber sleeve soft cable for coal mine.
Background technology
At present, the conductor of the mine movable cable of colliery industry is mostly the zinc-plated soft copper conductor of the structure that tangles again, insulation is comprised of ethylene-propylene rubber, sheath is neoprene or the fire-retardant rubber of haloflex, in sheath, not only contain halogen, but also contain the heavy metals such as plumbous cadmium, during use, can produce macro-corrosion halogen acid gas.In addition, the holistic cost of mine movable cable is high, tear resistance is poor, and the compatibility of screen and insulating barrier and rippability are difficult to balance.
Utility model content
Technical problem to be solved in the utility model is to overcome defect of the prior art, and a kind of moving metal shield monitor type rubber sleeve soft cable for coal mine is provided, and has the performances such as environmental protection, low cost, weatherability be strong.
For solving the problems of the technologies described above, the utility model provides a kind of moving metal shield monitor type rubber sleeve soft cable for coal mine, comprise three power cores that are triangularly arranged, power core is followed successively by power line core conductor, conductor screen, insulation and insulation shielding from inside to outside, power core is provided with stranding lapping layer, inner sheath, supervision layer, insulation twining package tape and oversheath outward successively, between power core and stranding lapping layer, be provided with filling, inner sheath and oversheath are that ethylene-octene mixture extrudes and forms.
As further improvement of the utility model, conductor screen is that the semiconducting rubber of ethylene vinyl acetate and the fine composition of hydrogenation fourth extrudes and forms.
As further improvement of the utility model, the rubber mixture that insulation is comprised of ethylene-octene mixture and ethylene-propylene rubber extrudes and forms.
As further improvement of the utility model, insulation shielding is that semi-conductive layer and metal screen layer form jointly, semi-conductive layer is the semiconducting rubber of ethylene vinyl acetate and the fine composition of hydrogenation fourth, and metal screen layer is that zinc-plated soft copper silk and aramid fiber yarn mixed weaving form.
As further improvement of the utility model, monitor that layer comprises two-layer semiconductive band and three supervision cores among two-layer semiconductive band, three monitor that cores are evenly stranded with the interval of 120 degree.
The beneficial effect that the utility model reaches is embodied in:
1, sheath of the present utility model is to be extruded and made by ethylene-octene mixture, and during cable fire, without halogen acid gas, the amount of being fuming is low, without dioxin, produces, and can reuse.
2, insulation of the present utility model is that the rubber mixture that is base-material by ethylene-octene mixture and ethylene-propylene rubber extrudes and makes, and production cost is low, serviceability good.
3, semiconductive shielding layer of the present utility model is extruded and is formed by ethylene vinyl acetate and the fine semiconducting rubber forming of hydrogenation fourth, be less than 20N/cm with the bonding force after insulating barrier composite sulfuration, can solve compatibility and the very difficult problem of rippability of screen and insulating barrier.
Accompanying drawing explanation
Fig. 1 is the structural representation of moving metal shield monitor type rubber sleeve soft cable for coal mine.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, the utility model provides a kind of moving metal shield monitor type rubber sleeve soft cable for coal mine,
Comprise three power cores that are triangularly arranged, power core is followed successively by power line core conductor 1, conductor screen 2, insulation 3 and insulation shielding 4 from inside to outside, power core is provided with successively stranding lapping layer 6, inner sheath 7 outward, monitors layer 8, insulation twining package tape 9 and oversheath 10, between power core and stranding lapping layer 6, be provided with and fill 5, inner sheath 7 and oversheath 10 form for ethylene-octene mixture extrudes; The semiconducting rubber that conductor screen 2 is ethylene vinyl acetate and the fine composition of hydrogenation fourth extrudes and forms; The insulation 3 rubber mixtures that are comprised of ethylene-octene mixture and ethylene-propylene rubber extrude and form; Insulation shielding 4 forms jointly for semi-conductive layer and metal screen layer, semi-conductive layer is the semiconducting rubber of ethylene vinyl acetate and the fine composition of hydrogenation fourth, metal screen layer is that zinc-plated soft copper silk and aramid fiber yarn mixed weaving form, conductor screen 2, insulation 3, insulation shielding 4 adopt three-layer co-extruded technology, guarantee three layers and combine closely; Monitor that layer 8 comprises that two-layer semiconductive band and three 11, three of supervision cores among two-layer semiconductive band monitor that cores 11 are evenly stranded with the interval of 120 degree.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and distortion, these improvement and distortion also should be considered as protection range of the present utility model.
