Abstract

The utility model relates to a novel cable, which comprises an outer sheath positioned on the outermost layer and a metal shielding layer positioned on the inner side of the outer sheath. The metal shielding layer wraps a cable core. The cable core comprises an insulation protective layer, a filler and a cable core unit. The cable core is wrapped and protected by the insulation protective layer, the filler is fiber-reinforced plastic (FRP), and the cross section of the cable core unit has a shape of an isosceles triangle. Five cable core units with isosceles triangle-shaped cross sections are twisted together to form a firm structure with a regular pentagon-shaped cross section, so as to avoid relative movement among the cable core units. Each cable core unit comprises a triangular insulating layer, FRP, an insulation protective layer and a conductor unit. The cable core units are twisted and then are wrapped by the filler.

Description

A kind of new-type cable

Technical field

The utility model belongs to the cables manufacturing technical field, is specifically related to a kind of new-type cable.

Background technology

Progress along with society, people's material and cultural life quality progressively improve, and social electric utility is in develop rapidly, society to cable demand increasing, high power cable is the active demand of society, and anti-flammability height, the cable that hardness is strong more are subjected to showing appreciation for somebody of people.For common cable, because packing material does not enrich, the cable internal structure still can enter a large amount of air, make the insulation effect of cable obvious inadequately, and the insulating barrier shape of cable internal element, may make in transportation or implementation process, to do relatively between the cable unit and move, thereby can produce potential impact the useful life of cable.

Summary of the invention

At the design feature of cable, the utility model proposes a kind of new-type cable with premium properties, the relaxation that this cable has suppressed between the unit takes place, and has improved the performance of cable, and concrete technical scheme is:

Form a conductor element by 7 conductors that twist together, the conductor element outside is extruded by insulating barrier, forms the insulation protective jacket of conductor element; Conductor element and insulation protective jacket are wrapped up by glass fibre, play water stop function, by triangle insulating barrier parcel, constitute the cable core unit then, and the number of cable core unit is 5; Stranded back, cable core unit is wrapped by filler; 5 cable core unit after wrapped are insulated protective layer and extrude, and form cable core; Cable core is extruded by metal screen layer, forms the shielding cable core; The shielding cable core is wrapped up by oversheath, forms cable.

Compared with the prior art, the utility model has following advantage:

1) after a plurality of stranded arrangements in cable core unit that are shaped as isosceles triangle, twine parcel, and insulating protective layer extrudes, be difficult for moving relatively, and formed good air insulated by filler.

2) added metal screen layer in the oversheath, made cable and extraneous isolated.

3) the utility model is easy to implement, and the technological requirement difficulty is little.

Description of drawings

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a planing surface structural representation of the present utility model.

Among the figure, 1. oversheath; 2. metal screen layer; 3. cable core; 4. insulating protective layer; 5. filler; 6. cable core unit; 7. triangle insulating barrier; 8. glass fibre; 9. insulation protective jacket; 10. conductor element.

Embodiment

Consult Fig. 1, shown in Figure 2, the utility model skin is an oversheath 1, toward interior be metal screen layer 2, metal screen layer 2 is wrapped in cable core 3, cable core 3 comprises insulating protective layer 4, filler 5, cable core unit 6; Insulating protective layer 4 is the outer wrapping protective layer of cable core, and filler 5 is glass fibre (FRP), and the cross section of cable core unit 6 is an isosceles triangle; Twist together by five isosceles triangle cable core unit 6, can constitute the structure that firm cross section is a regular pentagon, make to be difficult between the cable core unit 6 moving relatively.Cable core unit 6 comprises triangle insulating barrier 7, glass fibre 8, insulation protective jacket 9 and conductor element 10; 6 stranded backs, cable core unit are wrapped by filler 5.
