Abstract
The utility model discloses a full-shielding power cable comprising three main cable cores, a neutral conductor, insulating layers and shielding layers; the neutral conductor has a round cross section and is positioned at the center of the cable; the three main cable cores have tile-shaped cross sections and evenly surround the periphery of the neutral conductor; and the insulating layers are coated at the outer surfaces of the main cable cores and the neutral conductor, and are arranged at the outer layer of the insulating layers at the outer surfaces of the three main cable cores. In the utility model, the round neutral conductor is arranged at the center of the cable, the three main cable cores have tile-shaped cross sections and evenly surround the periphery of the neutral conductor, and simultaneously the neutral conductor and the main cable cores are externally insulated, so that the cable has a round appearance, a stable structure and high safety.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of full-shield power cable.
Background technology
Along with the fast development of human urbanization, 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 are 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, owing to three master cores and a neutral core irregular arrangement, 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, owing to the bigger space of existence in the cable core, so the arrangement of the insulated wire cores in the cable is unstable, and irregular " snakelike " can appear in the cable outer surface that causes processing, and influences the quality of product.
4, the shielding of this kind cable is bad, and the interference for electromagnetic field does not have shielding action.
The utility model content
The purpose of this utility model is to solve the defective that prior art exists, and the full-shield power cable of a kind of profile rounding, Stability Analysis of Structures, advantages of good shielding performance is provided.
The technical scheme that realizes the utility model purpose is a kind of full-shield power cable, comprises three master cores, neutral conductor, insulating barrier and screens; The cross section of described center conductor is circular, is positioned at the center of cable; The cross section of described three master cores is a watt shape, evenly is centered around the periphery of center conductor; The outer surface of described three master cores and neutral conductor all is extruded with insulating barrier; Described screen is arranged on the skin of insulating barrier of the outer surface of three master cores.
Described screen is the structure of the vertical bag of combarloy band argon arc sealing, continuous helical embossing.
Above-mentioned cable also comprises the outer jacket of the outside that is arranged on screen.
Described insulating barrier and outer jacket are silicon rubber.
Adopted technique scheme, the utlity model has following beneficial effect: (1) the utility model is placed on the neutral conductor of circle at the center of cable, three master cores are made the structure of cross section for watt shape, evenly be centered around the neutral conductor periphery, simultaneously neutral conductor and master core all are provided with insulation outward, make cable profile rounding of the present utility model, Stability Analysis of Structures, safe.
(2) that the outside diameter of cable has been dwindled compared to prior art is about 20% in the structure setting of this neutral conductor of the present utility model and master core, has reduced cable cost.
(3) screen of the present utility model adopts the vertical bag of combarloy band argon arc sealing, continuous helical embossing structure, realized that whole cable is convenient to bending, complete closed shield effect, shielding rejection coefficient＜0.001, can suppress irradiation of electromagnetic waves and conduction effectively, guarantee that cable moves reliably and with long-term and lay the maximum adaptation of environment.
(4) the utility model temperature resistant grade height, working temperature can reach 1800 ℃, and the ampacity by conductor can increase greatly.
(5) the utility model is easy to control in actual production, can guarantee product quality, and technology controlling and process is simple;
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail below, wherein:
Fig. 1 is a cross section structure schematic diagram of the present utility model.
Label is in the accompanying drawing: three master cores 1, neutral conductor 2, insulating barrier 3, screen 4, outer jacket 5.
Embodiment
(embodiment 1)
See Fig. 1, a kind of full-shield power cable of present embodiment comprises three master cores 1, neutral conductor 2, insulating barrier 3, screen 4 and outer jacket 5.
The cross section of center conductor 2 is circular, is positioned at the center of cable.The cross section of three master cores 1 is a watt shape, evenly is centered around the periphery of center conductor 2; The outer surface of three master cores 1 and neutral conductor 2 all is extruded with the insulating barrier 3 of silicon rubber material.The master core 1 of three tape insulation layers 3 and the neutral conductor of tape insulation layer 32 stranded title cable cores.Screen 4 is arranged on the skin of insulating barrier 3 of the outer surface of three master cores 1.Screen 4 is the vertical structure that is wrapped in cable core skin, continuous helical embossing of combarloy band argon arc sealing.The outer jacket 5 of silicon rubber material is arranged on the outside of screen 4.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
