Abstract
The utility model discloses a rubber jacketed flexible cable with the rated voltage equal to or lower than 660/1140V for a coal mining machine. A cable core comprises three cable conductors and a control cable, rubber insulating layers wrap the cable conductors, the outer diameter of each cable conductor is equal to that of the control cable, the three cable conductors and the control cable are arranged to form a square, a grounding wire wrapped with an insulating layer is arranged in a gap among the three cable conductors and the control cable, the control cable comprises three control cable conductors wrapped with insulating layers, an independent grounding wire is arranged in a gap among the three control cable conductors, an aluminum foil mylar wraps outer sides of the three control cable conductors, fillings are filled in gaps among the aluminum foil mylar and the three control cable conductors, a tensile steel wire is arranged in each filling, and a rubber sheath layer is extruded outside the three cable conductors and the control cable. The independent grounding wire is added in the control cable, so that safety of the cable is improved; stability of the cable is improved owing to triangular holes; and flexibility and tensile strength of the cable are improved owing to the tensile steel wires in the holes.
Description
Technical field
The utility model relates generally to field of cables, relates in particular to a kind of rated voltage 660/1140V and following coal-winning machine rubber sleeve flexible cable.
Background technology
Mining cable is the abbreviation of colliery with cable, and mining cable is flame retardant cable, all should pass through the national mining product safety sign of peace mark center and issue mining product safety sign certificate.
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first in the world electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, coal mining, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.
Coal-mining development grows stronger day by day, and people's awareness of safety constantly strengthens, and the performance and the environmental requirement of the cable supporting with it also improved constantly.Therefore, be badly in need of a kind of high temperature resistant, good flame resistance, safe mining power set with moving the cable that lays.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of rated voltage 660/1140V and following coal-winning machine rubber sleeve flexible cable to be provided.
The utility model is realized through following technical scheme:
Rated voltage 660/1140V and following coal-winning machine rubber sleeve flexible cable; Include cable core; It is characterized in that: described cable core includes three cable conductor and control cable of being enclosed with the rubber insulation layer; Three cable conductors equate and are square arrangement with the control cable external diameter, and the gap between described three cable conductors and the control cable is provided with an earth connection that is enclosed with insulating barrier, and described control cable includes three control cable conductors that are enclosed with insulating barrier; Three control cable conductors are isosceles triangle and arrange; Gap between three control cable conductors is provided with an independent grounding line, and described three control cable conductors outside is enclosed with one deck aluminium foil wheat and draws, the aluminium foil wheat draw and three control cable conductors between to be filled with the cross section be leg-of-mutton filler in the gap; Be provided with the cross section in the filler and be circular tension steel wire, three cable conductors and a control cable are extruded with the rubber restrictive coating outward.
The thickness of the thinnest part of described restrictive coating is not less than 6.0mm.
Described filler is the polyethylene foamed inserts.
The utility model has the advantages that:
The utility model is simple in structure, manufacturing is convenient; Its good flame resistance, high temperature resistant has increased the independent grounding line in the control cable, improved the fail safe of cable; The tri-angle-holed stability that increases cable, the tension steel wire in the hole has increased the pliability and the pull resistance of cable.
