It the features such as rotten and antisitic defect, can be laid in tunnel or cable duct.The distributor point for controlling cable from electric system is straight electric energy
Connect the electric power connection line road for being transferred to various electrical equipment utensils.Control cable belongs to appliance equipment cable and power cable
It is 2 in five major class of cable.Its structure and power cable are substantially similar, all include core (conductor), insulating layer, shielded layer and
Four part of protective layer.Core is the current-carrying part for controlling cable, is the major part for controlling cable for conveying electric energy.Insulation
Layer is will to be electrically isolated from each other between core and the earth and out of phase core, guarantees electrical energy transportation, is control cable knot
Indispensable component part in structure.The effect of protective layer be protect control cable from introduced contaminants and moisture intrusion, with
And prevent external force from directly damaging control cable.
In control cable between the different cores of same cable, all there is electrical Interference close between the cable of parallel lay-up
The problem of, Chinese invention patent publication number CN103226999A discloses control cable for flame-retardant fireproof boat and its manufacturing method,
The periphery of twisted copper conductors is uniformly extruded with the ethylene propylene rubber insulated layer of flame-retardant and constitutes control insulated cable core, more controls
Insulated cable core is mutually twisted to constitute control cable conductor, and the periphery for controlling cable conductor is enclosed with low-intensity non-woven fabrics longitudinal wrap
Layer, the periphery of low-intensity non-woven fabrics longitudinal wrap layer are extruded with inner sheath, and the periphery of inner sheath is coated with armouring braiding layer, armouring braiding
The periphery of layer is extruded with oversheath.It is in close contact between each core of this kind control cable, it is electrical dry between each core
It disturbs more serious.
Summary of the invention
The technical problem to be solved by the present invention is to there are electrical Interference, influences between each core of existing control cable
The normal work of cable provides a kind of anti-interference type control cable thus.
The technical scheme is that anti-interference type controls cable, it includes several cores, the insulation that is coated on outside core
Layer and protective layer, it further include center isolation harness, the core be centered around center isolation harness around and it is tangent with it, it is adjacent
There are certain interval between the insulating layer of two cores, the center isolation harness is connected with the separator by the gap, institute
The inner surface of the end and protective layer of stating separator is affixed.
Separator described in above scheme is tangent with the insulating layer of some core between the gap, so that separator
It is arc-shaped.
Separator described in above scheme is flexible element.
The improvement of above scheme is that the radially-outer surface of the protective layer is equipped with opening and closing part, and the opening and closing part includes outer layer
The part of fitting portion and internal layer fitting portion, the outer layer fitting portion and the overlapping of inside fitting portion is equipped with the gear line being engaged with each other.
Gear line described in above scheme is in inwardly narrowed arc.
The further improvement of above scheme is that the outer surface of the outer layer fitting portion is connected with knob.
The beneficial effects of the invention are as follows a center isolation harness is arranged at control cable center each core is isolated
Open, and separator be set between the gap between two neighboring core, prevent contacting with each other for core, guarantee adjacent core it
Between will not generate electrical Interference, it is ensured that control cable steady operation；The presence of opening and closing part to control cable maintenance conveniently, is opening
Outer layer fitting portion is pulled open in conjunction portion outward, so that it may which smooth opening controls the protective layer of cable, without cutter to protective layer
It is stripped.
