Description
Technical field
The utility model relates to a kind of coal rubber sheathed flexible cable for mine.
Background technology
Mining cable refers to the coal mining industry ground installation of will and underground equipment electric wire cable product. comprising coal-winning machine, transporter, communicate, illumination and signalling arrangement cable, and electric drill cable, the feed cable etc. of cap lamp electric wire and underground moving transformer station.
MY-0.38/0.66kV, MYP-0.38/0.66kV and MYP-0.66/1.14kV coal mine moving rubber sleeve flexible cable is the mining flame-retardant cable that People's Republic of China's coal industry (unification) designs, and product is used for the power supply connection that underground coal mine rated voltage is the various underground moving coal excavation apparatus of 0.38/0.66kV or 0.66/1.14kV.
In actual use, tensile strength can not meet the demand of actual working environment to original mining cable completely, does not have enough dielectric strengths between power wire core and ground connection core, and be easily short-circuited the defects such as fault.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of colliery four-core rubber sleeve flexible cable, improves insulation property and the tensile property of cable.
The technical solution adopted in the utility model is: a kind of coal rubber sheathed flexible cable for mine, comprise control conductor conductor, power wire core conductor, earth connection core conductor, described control conductor conductor, power wire core conductor, earth connection core conductor conductor is enclosed with insulating barrier outward respectively, described insulating barrier nominal thickness is 1.4-2.0mm, three described power wire core conductors, earth connection core conductor is mutual stranded formation cable core centered by packed layer, 3 leg-of-mutton tensile steel wire are evenly equipped with outside cable core, described packed layer center is provided with the tension rope that cross section is the braiding of leg-of-mutton filament, the outer extrusion moulding of cable core has restrictive coating, restrictive coating center is provided with the reinforced layer that one deck nylon cloth is woven into.
As further improvement of the utility model, described insulating barrier nominal thickness preferably 1.8 mm.
The beneficial effects of the utility model are: this practical structural design advantages of simple, and conduct electricity very well, have enough dielectric strengths between core, be not easily short-circuited fault.Packed layer center is provided with tension rope and coordinates the circle reinforced layer in restrictive coating, the tensile steel wire outside cable core, the tensile property of cable is risen to new height, the overall performance of cable is improved, extends useful life.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Shown in figure: 1 control conductor conductor, 2 power wire core conductors, 3 earth connection core conductors, 4 insulating barriers, 5 tensile steel wire, 6 restrictive coatings, 7 reinforced layers.
Embodiment
Below in conjunction with Fig. 1, the utility model is described further.
As shown in Figure 1, a kind of coal rubber sheathed flexible cable for mine, comprise control conductor conductor 1, power wire core conductor 2, earth connection core conductor 3, described control conductor conductor 1, power wire core conductor 2, earth connection core conductor 3 conductor is enclosed with insulating barrier 4 outward respectively, described insulating barrier nominal thickness is 1.8mm, three described power wire core conductors, earth connection core conductor is mutual stranded formation cable core centered by packed layer, 3 leg-of-mutton tensile steel wire 5 are evenly equipped with outside cable core, described packed layer center is provided with the tension rope that cross section is the braiding of leg-of-mutton filament, the outer extrusion moulding of cable core has restrictive coating 6, restrictive coating center is provided with the reinforced layer 7 that one deck nylon cloth is woven into.
Those skilled in the art should know; protection scheme of the present utility model is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to the utility model spirit, the various conversion that the utility model carries out all are dropped in protection range of the present utility model.
