Abstract
The utility model discloses a plastic insulating control cable. The plastic insulating control cable comprises a cable core, a filling layer is arranged in gaps of the cable core, a warping tape, a shielding layer and a lining layer are sequentially extruded outside the cable core, an armor layer is woven outside the lining layer, an outer sheath is extruded at the outermost layer of the cable core, the cable core is formed by twisting three layers of concentrically-arranged insulating wire cores, the first layer includes four insulating wire cores at the center, the second layer includes 10 wire cores, and the third layer includes 16 wire cores. Each insulating wire core is composed of a conductor and an insulating layer coated outside the conductor. The plastic insulating control cable has the characteristics of good abrasion resistance, good flame resistance, good controllability, simple structure, long service life and the like.
Description
Technical field
The utility model relates to the electric wire field, specifically refers to a kind of plastic insulation control cables.
Background technology
At present, along with social development, the consumption on naval vessel also increases thereupon, requires the current capacity of cable increasing, and the interface of the cable conductor of cable constantly increases, and the weight of the unit length of cable increases thereupon., be easy to abrade oversheath in process of deployment, thereby stay hidden danger to safety when carrying out cable laying work as the staff, cause having an accident.In prior art, the insulating barrier of cable and sheath great majority are the organic mixtures that adopt plastic casing rubber, and resistance to wear is poor.During fire, flame can spread along with cable, also can produce a large amount of smog and poisonous corrosive gas simultaneously, and human body is produced to harm.The speed spread along cable in order to reduce flame combustion the time adds various flame-retardant additives, usually to make various types of fire proofings and flame retardant cable in cable material.Performance while therefore, generally by anti-flammability, corrosivity, smokiness, toxicity, evaluating the power cable burning.
The utility model content
Technical problem to be solved in the utility model is to provide that a kind of resistance to wear is good, good flame resistance, controlled good, simple in structure, the plastic insulation control cables of long service life.
A kind of plastic insulation control cables described in the utility model, comprise cable core, in the gap of cable core, is provided with packed layer, and cable core extrudes twining package tape, screen, inner covering outward successively, and inner covering weaves armour outward, and the cable core outermost layer extrudes oversheath; Described cable core is stranded the forming of insulated wire cores of arranging by concentric manner by three layers, and centered by ground floor 4, the second layer is 10, and the 3rd layer is 16.
Further improve, described insulated wire cores is by conductor and be coated on the conductor external insulation layer and form.
Further improve, described screen adopts the circular copper wire braiding, copper strips is wrapped or aluminium-plastic tape is wrapped again.
The beneficial effects of the utility model are:
Compared with prior art, it is simple in structure that the utility model cable adopts, and when cable is on fire, the carburization zone that inner covering, oversheath form heat insulation resistance oxygen plays protection to cable, thereby stop flame cable expansion burning; The wire armoring structure has also improved the shielding of cable in addition, thereby has improved the useful life of cable.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of plastic insulation control cables described in the utility model, comprise cable core, be provided with packed layer 3 in the gap of cable core, cable core extrudes twining package tape 4, screen 5, inner covering 6 outward successively, the outer braiding armour 7 of inner covering 6, and the cable core outermost layer extrudes oversheath 8; Described cable core is stranded the forming of insulated wire cores of arranging by concentric manner by three layers, and centered by ground floor 4, the second layer is 10, and the 3rd layer is 16.Described insulated wire cores is by conductor 1 and be coated on conductor 1 external insulation layer 2 and form.
Screen 5 described above adopts the circular copper wire braiding, copper strips is wrapped or aluminium-plastic tape is wrapped.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
