Abstract
The utility model relates to a composite cable. The composite cable comprises a communication cable core, a metal braid shielding layer wrapped outside the communication cable core, an insulating layer A wrapped outside the metal braid shielding layer, three power cable cores disposed outside the insulating layer A, phase insulating layers wrapped outside the power cable cores, a liner layer wrapped outside the phase insulating layers, and an armour wrapped outside the liner layer. The mine composite cable is provided with the three power cable cores and the communication cable core, so the mine composite cable can transmit three-phase AC and communication signals at the same time. Thus, wiring in a mine is simple and saves cost. The metal braid shielding layer can effective ensure stability of transmission signals in the communication cable core and prevent interference phenomenon. The insulating layer A makes the communication cable core isolate with the external world. The phase insulating layers ensure insulating properties of each of phase lines. The liner layer protects the inside from corrosion of air and water. The armour is made of steel wires or steel strips to improve intensity of the cable.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of compound cable.
Background technology
As everyone knows, mining cable refers to ground installation and the underground equipment electric wire cable product that coal mining industry is used.Comprising the mining power cable to the power supply of coal-winning machine, transporter, communication, illumination and electric drill cable, connect various device and realize the communication cable for mine of control, mining control cable etc., because the applied environment of mining cable is abominable and it will satisfy mechanical strength and anti-flammability, therefore the cost of mining cable is higher, and need to lay various types of power cables, telecommunication cable in the mine, make use cost increase.
Summary of the invention
The utility model provides the mining compound cable of one kind of multiple purposes in order to overcome the deficiency of above technology.
The technical scheme that its technical problem that overcomes the utility model adopts is:
This mining compound cable comprises the communication cable core, is wrapped in the outer metal knitted screen of communication cable core, is wrapped in the outer insulating barrier A of metal knitted screen, is arranged at three outer electric power cable cores of insulating barrier A, is wrapped in the outer phase insulating barrier of electric power cable core, is wrapped in the outer laying of phase insulating barrier and is wrapped in the outer armouring of laying.
In order to prevent that armouring and laying from damaging because the phase mutual friction causes laying, also comprises the protective layer that is arranged between armouring and the laying.
In order further to improve insulation property, also comprise the insulating barrier B that is arranged between phase insulating barrier and the laying.
In order to improve the tensile strength of this mining compound cable, also comprise the filling rope made of hemp that is arranged between insulating barrier B and the insulating barrier A.
In order to transmit the computer network signal, also comprise eight computer network cable cores being arranged among the insulating barrier A, be arranged at the outer screen of computer network cable core and be arranged at the outer oversheath of screen.
The beneficial effects of the utility model are: owing to be provided with three electric power cable cores in this mining compound cable and therefore the communication cable core can transmit three-phase alternating current and communication signal simultaneously, make that therefore wiring is simple under the ore deposit, save cost.Metal knitted screen can effectively guarantee the stability of communication cable core transmission signal, prevents interference phenomenon, and insulating barrier A can make communication cable core and external insulation.The phase insulating barrier can be guaranteed the insulation property of every phase line, and laying can be protected the inner corrosion that is not subjected to the sky G﹠W, and armouring adopts steel wire or steel band to make, and bears the intensity that mechanical force is strengthened cable with raising.
