Description
Technical field
The utility model relates to field of cable technology, more specifically to a kind of coal-winning machine flame retardant cable.
Background technology
Coal-winning machine is one and integrates large-scale complicated system that is mechanical, electric and hydraulic pressure, and work under bad environment, will cause the interruption of whole coal work if there is fault, cause huge economic loss.When electric cable for coal mining machine is energized, can generate an electromagnetic field during electricity and form electrostatic around, in case of pernicious explosion accident often occurs high concentration gas, this just requires that cable for coal cutter possesses good interference free performance.In addition, existing electric cable for coal mining machine fire resistance is poor, when running into naked light, easily burns, and affects the safety of Signal transmissions and mine site.The problems referred to above need solution badly.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of coal-winning machine flame retardant cable, to solve the problems of the technologies described above.
A kind of coal-winning machine flame retardant cable that the utility model proposes, comprise cable core, described cable core comprises many parallel longitudinal wires, wire comprises the conductor being positioned at middle part and the insulating barrier being coated on conductor outside, fire-retardant filler is filled with between wire, make described cable core have circular cross-section, fire-retardant filler is provided with multiple louvre along its length; Described cable core outside is formed with lapping layer by Mica tape; lapping layer outside is coated with screen; screen outside is formed with flame-retardant layer by extruding ceramic silicon rubber; flame-retardant layer outside is coated with copper strips protective layer; copper strips protective layer outside is coated with polyethylene inner restrictive coating; polyethylene inner restrictive coating outside is coated with external sheath layer, and external sheath layer adopts bridging property polyolefin material to make.
Preferably, conductor adopts many copper wires to be hinged to form.
Preferably, screen is tincopper fuse wire braided armor.
Preferably, louvre distributes circlewise around described cable core axis.
A kind of coal-winning machine flame retardant cable that the utility model proposes,
For a kind of coal-winning machine flame retardant cable that the utility model proposes, the design of inner restrictive coating improves the flame retardant effect of cable, copper protective layer also can the transmission of trap heat while playing shielding action, and flame-retardant layer and when external temperature is too high, hard ceramic oxide layer can be formed, the further transmission of trap heat, the design of lapping layer and fire-retardant filler, the thermogenetic heat of companion can be hindered outwards to conduct, promote flame retardant effect further, the design of the louvre in fire-retardant filler then can make to form heat trnasfer between cable and inner air, be conducive to heat radiation, improve the useful life of cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of coal-winning machine flame retardant cable that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of coal-winning machine flame retardant cable that the utility model proposes.
With reference to Fig. 1, a kind of coal-winning machine flame retardant cable that the utility model proposes, comprise cable core, described cable core comprises many parallel longitudinal wires 1, wire 1 comprises the conductor 11 being positioned at middle part and the insulating barrier 12 being coated on conductor 11 outside, be filled with fire-retardant filler 2 between wire 1, make described cable core have circular cross-section, fire-retardant filler 2 is provided with multiple louvre 3 along its length; Described cable core outside is formed with lapping layer 4 by Mica tape; lapping layer 4 outside is coated with screen 5; screen 5 outside is formed with flame-retardant layer 6 by extruding ceramic silicon rubber; flame-retardant layer 6 outside is coated with copper strips protective layer 7; copper strips protective layer 7 outside is coated with polyethylene inner restrictive coating 8; polyethylene inner restrictive coating 8 outside is coated with external sheath layer 9, and external sheath layer 9 adopts bridging property polyolefin material to make.
In such scheme, the design of inner restrictive coating 8 improves the flame retardant effect of cable, copper protective layer 7 also can the transmission of trap heat while playing shielding action, and flame-retardant layer 6 and when external temperature is too high, hard ceramic oxide layer can be formed, the further transmission of trap heat, the design of lapping layer 4 and fire-retardant filler 2, the thermogenetic heat of companion can be hindered outwards to conduct, promote flame retardant effect further, the design of the louvre 3 in fire-retardant filler 2 then can make to form heat trnasfer between cable and inner air, be conducive to heat radiation, improve the useful life of cable.
Screen 5 and copper protective layer 7 play double layer screen effect, and particularly, screen 5 is tincopper fuse wire braided armor, and shield effectiveness is better, and external sheath layer 9 adopts bridging property polyolefin material to make, low smoke and zero halogen, good flame retardation effect.
Conductor 1 adopts many copper wires to be hinged to form, and is conducive to the intensity strengthening conductor 1.
Louvre 3 distributes circlewise around described cable core axis, and cable internal heat dissipating is more evenly good.
A kind of coal-winning machine flame retardant cable that the utility model proposes, compact conformation, strong anti-interference performance, has good fire-retardant and heat dispersion.
The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection range of the present utility model.
