Abstract
The utility model discloses a rubber sheath flexible cable for a coal cutter with rated voltage of 380/660V and below. The rubber sheath flexible cable comprises a cable core, wherein the cable core comprises three cable conductors coated with rubber insulating layers and a control cable; the three cable conductors and the control cable have the same outer diameter and are squarely arranged; a grounding wire coated with an insulating layer is arranged in a gap between the three cable conductors and the control cable; the control cable comprises three cable conductors coated with the insulating layers; an aluminum foil Mylar layer is coated on the outer side of the three control cables; a filler which has a circular section is filled in a gap between the aluminum foil Mylar layer and the three control cable conductors; a plurality of tensile steel wires are respectively arranged on the insulating layer of the three control cable conductors; and a rubber sheath layer is coated outside the three cable conductors and the control cable. The aluminum foil Mylar coated outside the cable core of the control cable has a function of a lapping tape and can be isolated from other cable conductors, and the tensile steel wires are arranged on the insulating layers of the control cables, so that the tensile property of the cable is improved.
Description
Technical field
The utility model relates generally to field of cables, relates in particular to a kind of rated voltage 380/660V and following rubber sleeve flexible cable for coal mining machine.
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 380/660V and following rubber sleeve flexible cable for coal mining machine to be provided.
The utility model is realized through following technical scheme:
Rated voltage 380/660V and following rubber sleeve flexible cable for coal mining machine; 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; 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, and three control cable conductors are isosceles triangle and arrange; 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 the gap be filled with the cross section for circular filler, be respectively equipped with many tension steel wires on the insulating barrier of three control cable conductors, 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, the aluminium foil wheat of the cable core outerwrap of control cable is drawn the effect of both playing band, and itself and other cable conductor is isolated; Increase the tension steel wire on the insulating barrier of control cable, increased the pull resistance of cable.
Description of drawings
Fig. 1 is the structural representation of the utility model.
