Abstract
The invention relates to the field of cable manufacture and discloses a novel insulated cable. Four main insulated cable cores and a control cable body are arranged in the middle of the insulated cable. The main insulated cable cores are sequentially connected through connecting ribs. A metal shielding layer, a polyethylene insulating layer and an outer protective layer are sequentially arranged outside the main insulated cable cores. The metal shielding layer is formed by metal wires or metal bands in a weaving or wrapping mode. The portions among the main insulated cable cores, the control cable body and the metal shielding layer are all filled with glass silk. According to the novel insulated cable, the main insulated cable cores are connected through the connecting ribs and the control cable body are additionally arranged, so that information is received and fed back; in addition, the main insulated cable cores are physically isolated completely in the process of use, transmission conducted by the main insulated cable cores are not disturbed mutually, the quality and the safety are effectively guaranteed, the novel insulated cable can be widely applied to projects such as communication, limited televisions and electric power in urban and rural power grids, the application prospect is wide, and good social benefits and economic benefits can be brought.
Description
Technical field
The present invention relates to cables manufacturing field, relate in particular to a kind of New insulated cable.
Background technology
Parallel cluster New insulated cable (being called for short: parallel gathering lead wire in low) is one of product of applying in State Power Corporation's Rural Power Grid Construction " 15 " program for the development of science and technology.Parallel gathering lead wire in low adopts three-phase and four-line power supply, distribution transforming three-phase load degree of unbalance is down to minimum, reduces neutral current, thereby reduces resistance loss.Owing to adopting the symmetrical splitted construction of tight type, the inductance of wire is reduced, strengthen dielectric constant between line, capacitance increases, and circuit reactance is significantly reduced, and finally realizes dilatation and fall the object of damage.
Generally, electromagnetic shielded cable structure is from the inside to the outside followed successively by the core, the insulating medium layer that is coated on cable core outer surface, screen and the oversheath that form inner wire.Wherein, cable core is used for transmission of electric signals, and material is take copper or ormolu as main.Screen is generally layer of metal foil, in order to shield electromagnetic interference or useless external signal, disturbs.For layer of metal foil volume, overlay on the screen that insulating medium layer forms outward, be covered in outside insulating medium layer after need being pre-formed layer of metal foil.This type of screen well below the speed of production of cable system core, is the principal element of restriction electromagnetic shielded cable volume production in speed of production.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of novel cable, overcome that in prior art, insulation effect is poor, toughness is not enough, use in the defect such as uncontrollable feedback.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of New insulated cable, is four main insulation cores and a control cables in the middle of this cable, and described main insulation core connects successively by dowel, and main insulation cable core is provided with metal screen layer, polyethylene layer, external protection outward successively.
Preferably, described main insulation core comprises master core conductor, at master core conductor, sets gradually master core insulating barrier, master core metal screen layer outward.
Preferably, described main insulation core squarely diagonal angle is arranged.
Preferably, described control cables is in the square centre of described main insulation core.
Preferably, described metal screen layer adopts wire or metal tape braiding or wrapped.
Preferably, between described main insulation core, control cables and metal screen layer, be all filled with glass fiber.
Beneficial effect of the present invention is: this uses novel employing dowel to connect master core and access control cable is realized information reception and feedback, between master core, can produce in use in addition physics isolates completely, its transmission is not interfere with each other, quality and safety have effectively been guaranteed, can be widely used in the engineering such as communication, limited TV, electric power in urban and rural power grids, there is the wide application prospect of sending out, and can bring good Social benefit and economic benefit.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical scheme of the present invention is done further and illustrated.

Embodiment
Below in conjunction with specific embodiment, technical scheme of the present invention is described further:
As shown in Figure 1, a kind of New insulated cable, in the middle of this cable, be four main insulation cores 2 and a control cables 3, main insulation core 2 connects successively by dowel 1, main insulation cable core 2 is outer is provided with metal screen layer 5, polyethylene layer 6, external protection 4 successively, better protection cable, increases useful life and the fail safe of cable; Main insulation core 2 comprises master core conductor 201, sets gradually master core insulating barrier 202, master core metal screen layer 203 outside master core conductor 201, can produce physics and isolate completely during use, and its transmission is not interfere with each other, and has effectively guaranteed quality and safety; Main insulation core 2 squarely diagonal angles are arranged, the square centre that control cables 3 forms in described main insulation core 2; Metal screen layer 5 adopts wire or metal tape braiding or wrapped; Between main insulation core 2, control cables 3 and metal screen layer 5, be all filled with glass fiber 7, increase the tensile strength of cable.
It should be noted last that, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
