Abstract
The utility model discloses a fan-shaped structure core cable, which is characterized by comprising a plurality of fan-shaped cores and round cores, wherein the inner portion of the fan-shaped cores comprises a plurality of single-wire cores which are extruded into a fan shape, the outer portion is an insulating layer, the fan-shaped cores and the round cores are tightly and circumferentially arranged in the cable to form a cylinder, the outer portion is fixed by belting, and a sheath is arranged outside the belting. After adopting the fan-shaped structure, the structure is compact, which does not need filling materials, thereby reducing the diameter of the cable.
Description
Technical field
The utility model relates to a kind of cable of sector structure core.
Background technology
Traditional cable generally adopts circular configuration, when some spaces, particularly twin-core, three cores, four-core and five core strandings were all arranged between its core and the core, its space inner and side was all bigger, as filled the roundness of cable behind the very difficult assurance stranding without packing material.Packing material generally requires heat resistance consistent with the cable working temperature, can not impel the performance change that is in contact with it material, also will have non-water absorption or the like, causes the diameter of cable big, and structural instability, easy deformation, and manufacturing cost is big.Structure is badly in need of improving, to satisfy the requirement of user Geng Gao.
Summary of the invention
The purpose of this utility model provides a kind of cable of fan-shaped line cored structure, and the diameter of cable obviously reduces, and Stability Analysis of Structures, and is not yielding.
The technical scheme that the utility model provides is as follows:
A kind of sector structure core cable, it is characterized in that: include several sector structure cores and circular core, described sector structure core inside forms fan-shaped by many single line core extruding, the outside is an insulating barrier, described several sector structure cores and circular core closely be arranged around in the cable form cylindrical, its outside is fixed with band, and band is outward a sheath.
Described sector structure core cable is characterized in that: many single line cores of described sector structure core inside, and described single line core is circle single line core, adjacent strand layer differs 6 cores.
Described sector structure core cable is characterized in that: described sector structure core is three, and circular core is one.
In order to constitute the satisfactory sector structure core of profile, its central core all has parallel single line, in order to shaping.The strand layer that central core is outer, as the round single line with same diameter, its radical also is to differ 6 rule by adjacent strand layer to constitute, if with thinner single line, then by the allowed arrangement radical formation of outer pitch circumference, should consider to twist coefficient at this moment.
After adopting the fan-shaped line cored structure, reduced the diameter of cable, cost is lower by 15%～20% than circular core cable, and according to calculating, the stranded back of circular core and fan-shaped core insulation diameter ratio is in 1.20～1.25 scopes in similar cable.
Description of drawings
Fig. 1 is the structural representation of the fan-shaped core cable of the utility model.
Embodiment
Referring to Fig. 1, fan-shaped core cable includes several sector structure cores 1 and circular core 2, sector structure core 1 inside is formed by many single line core extruding, the outside is an insulating barrier, three sector structure cores 1 closely are arranged around with circular core 2 and constitute cylindrical shape in the cable, it is outside fixing with band 3, and band is outward a sheath 4, and the single line core is circle single line core.Adjacent strand layer differs 6 cores formations in the sector structure core 1.
The structure of fan-shaped core must satisfy following requirement, and the single line on the central core center line should be arranged on the fan-shaped center line equally, and the single line of fan-shaped periphery should be able to slide on central core, and two single lines of side also can slide in the central core.Power cable has following three kinds of execution modes with the structure of fan-shaped core: 6 (parallel)+12 piece are applicable to that the cross section is 25～70mm
2Core; 7+2 (parallel)+16, the single line of 16 layers is thinner, is applicable to that the cross section is 95～120mm
2Core; 7+2 (parallel)+15+21 root is applicable to that the cross section is 150～240mm
2Core.
Claims (3)
