The common failure of cable run has mechanical damage, insulation harm, humidified insulation, insulation ag(e)ing to go bad, the overheat event of overvoltage, cable
Barrier etc., in the Important Economic such as various industrial and mining enterprises, communications and transportation department, such as power plant, substation, power circuit and oil
In Gong Deng enterprises, control the application of cable very extensive, the operating pair with safe power supply machine production system, controls the function of cable
Even more than it is used for the power cable of backbone.
Existing control cable, researches and develops less at its fire-retardant aspect, and control cable is because inside at work
Heat generation is more, and control connector inner conductor fits together, and the heat of generation is difficult to distribute, at a higher temperature, absolutely
Edge layer may burn phenomenon, not only influence control cable normal work, when burning insulating layer may discharge smog,
The problem of pernicious gases such as poison gas, its job security is difficult to ensure, for this it is proposed that a kind of flame-proof control cable.
The content of the invention
It is an object of the invention to provide a kind of flame-proof control cable, to solve control electricity proposed in the above background technology
Cable is less its fire-retardant aspect research and development, and control cable is more because heat internal at work produces, and controls cable
Inner conductor fits together, and the heat of generation is difficult to distribute, and at a higher temperature, insulating layer may burn phenomenon,
The normal work of control cable is not only influenced, insulating layer may discharge the pernicious gases such as smog, poison gas when burning, its work
The problem of security is difficult to ensure.
To achieve the above object, the present invention provides following technical solution：A kind of flame-proof control cable, including external sheath layer,
The external sheath layer is internally provided with shielded layer, and the shielded layer is internally provided with liner layer, the interior table of the liner layer
Face is provided with separate layer, and the separate layer and liner layer are integral type, the gap that the inside of the liner layer is connected with separate layer
Place is provided with the filling of cable cream, and the cable cream filling is internally provided with insulating layer, and the cable that is internally provided with of the insulating layer is led
Body, the side for being internally located at insulating layer of cable cream filling are provided with fire resistant fluid protective layer, the fire resistant fluid protective layer it is interior
Portion is provided with liquid flame retardant.
Preferably, the separate layer is Y-shaped structure.
Preferably, the fire resistant fluid protective layer is provided with two altogether in the inside that cable cream is filled.
Preferably, the inner space of liner layer is evenly divided into three parts by the separate layer.
Preferably, the shielded layer is dredged around adding copper strips binding structure for binding for copper strips lapping layer or copper wire.
Compared with prior art, the beneficial effects of the invention are as follows：
（1）Control cable at a higher temperature, insulating layer may burn phenomenon, not only influence the normal work of control cable
Make, when burning, insulating layer may discharge the pernicious gases such as smog, poison gas, its job security is difficult to what is ensured, in cable
Be internally provided with liquid flame retardant, the fire resistant fluid protective layer of liquid flame retardant outer wall burnt when controlling resistance burning, liquid
Body fire retardant flows out, and improves the fire resistance of control cable to a certain extent, so as to improve the job security of control cable；
（2）Control cable more because heat internal at work produces, a plurality of conductor is fitted in liner layer inside control cable
Interior, the heat polymerization of generation is difficult to distribute, and at a higher temperature, insulating layer may burn phenomenon, will by separate layer
Control a plurality of conductor inside cable to separate in different interlayers, the heat build-up of cable can be reduced, improve dissipate to a certain extent
Hot property, and by setting different marks in separate layer, different conductors is passed through separate layer, when cable inner conductor needs
When maintenance or debugging, conductor can be fast and accurately found, also allows for the debugging maintenance of conductor.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention.
In figure：1- external sheath layers, 2- shielded layers, 3- liner layers, the filling of 4- cables cream, the resistance of 5- fire resistant fluids protective layer, 6- liquid
