Abstract
The utility model discloses a novel shielded power cable, which is characterized in that a round neutral line core is taken as a center, three tile-type mater line cores are arranged around the periphery of the round neutral line core, a silicon rubber insulating layer is respectively arranged among the tile-type mater line cores, and between the round neutral line core and each tile-type mater line core; a copper strip shielding layer is arranged on the outer layer of the three tile-type mater line cores; 4 to 6 sliver-plated copper lines which are used as drainage lines are longitudinally arranged on the inner side of the copper strip shielding layer; and the outside of the copper strip shielding layer is provided with an outer silicon rubber protective layer. The novel shielded power cable forms a totally-shielded cable structure, and has a round shape, stable structure, high-temperature-resistant capacity and high safety.
Description
Technical field
The utility model relates to cable, a kind of novel shielding power cable of more specifically saying so.
Background technology
Along with the fast development of human industry, more and more higher for the requirement of electrical safety reliability, in the power transmission and distribution project design, the fail safe of electrical network distribution and reliability will be considered as primary economic factor; In the actual production manufacture process, often there is the problem of following several respects in traditional power cable forms that adopt three master cores and neutral core and the common stranded stranding of protection core more:
1, because master core and neutral core or protection core are not uiform sections, thus cause cable not roundness do not reach standard-required;
2, the insulated wire cores in the cable becomes the polygon arrangement architecture, causes the outside diameter of cable bigger than normal, and cable cost is higher;
3, there is bigger space in the cable core,, makes the cable outer surface of processing irregular " snakelike shape " can occur, influence the quality of product so the insulated wire cores in the cable is arranged instability.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, and a kind of profile rounding, Stability Analysis of Structures, safe novel shielding power cable are provided.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model shielding power cable is to be the center with a neutral core of circle, three pieces watts of shape master cores are centered around the periphery of the neutral core of described circle, between each root watt shape master core, and between the neutral core of described circle and each root watt shape master core, be respectively arranged with silicone rubber insulation layer, skin at described three pieces watts of shape master cores is provided with the copper strips screen, vertically place the silver-plated copper cash of 4-6 root as drainage thread in the inboard of described copper strips screen, the outer setting of described copper strips screen has the silicon rubber outer jacket.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model profile rounding, Stability Analysis of Structures, safe;
2, that the outside diameter of cable has been dwindled than prior art is about 20% in structure setting of the present utility model, has reduced cable cost;
3, the utility model is easy to control in actual production, can guarantee product quality, and technology controlling and process is simple;
4, the utility model temperature resistant grade height, working temperature can reach 180 ℃, and the ampacity by conductor can increase greatly.
Description of drawings
Fig. 1 is the utility model structural representation.
Mark among the figure: 1 watt of shape master core, 2 circular neutral cores, 3 silicone rubber insulation layers, 4 drainage threads, 5 copper strips screens, 6 silicon rubber outer jackets.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1, present embodiment is to be the center with a neutral core 2 of circle, three pieces watts of shape master cores 1 are centered around the periphery of circular neutral core 2, between each root watt shape master core 1, and between the neutral core 2 of circle and each root watt shape master core 1, be respectively arranged with silicone rubber insulation layer 3, skin at three pieces watts of shape master cores 1 is provided with copper strips screen 5, vertically place the silver-plated copper cash of 4-6 root as drainage thread 4 in the inboard of copper strips screen 5, the outer setting of copper strips screen 5 has silicon rubber outer jacket 6.
In concrete the enforcement, circular neutral conductor 2 and three pieces watts of shape master cores 1 are twisted into cable core, and copper strips screen 5 is wrapped in the outside of cable core as protective layer, form the shield cable structure.
