Abstract
The invention discloses a hydraulic observation cable, which comprises two line sets, wherein each of the two line sets comprises two cores which are coated by shielding layers. The two line sets are parallel to each other, a ground wire is arranged in a gap between the two line sets, and protecting sleeves are sleeved on the two line sets. According to the hydraulic observation cable, the cable structure is compact on the basis that the cable performance can meet the requirements, so that the external diameter of the cable is reduced, the external diameters of the protecting sleeves are correspondingly reduced, the material consumption of the protecting sleeves is reduced, and the production cost of the cable is lowered; and besides, twisting process steps for the two line sets of the cable are reduced, and the cable structure is stable.
Description
Technical field
The present invention relates to a kind of hydraulic observation cable.
Background technology
Water is all lifesprings.Water brings world's boundless vital force, also brings infinite disaster to the world.No matter rational utilization of water resources is still prevented trouble before it happens, and all will build dykes and dams, build hydraulic engineering, and engineering state is supervised for a long time.The hydraulic observation cable is a part in the hydraulic observation system, and it is blood vessel and nerves of hydraulic observation system as the transmission line of various monitor signals.
As shown in Figure 1, be the cross-sectional view of a kind of hydraulic observation cable in the prior art.This hydraulic observation cable comprises two line groups, and forms a line group by two cores are stranded, and every core is by multiple conducting wires 1 stranded forming, and at multiple conducting wires 1 outerwrap insulating barrier 2; Outside each line group, be provided with separator 3, lapped shielding layer 5 outside separator 3, and ground wire 2 is located at outside the separator 3 and is wrapped in the screen 5; Comprise that also 6, two line groups of two non-hygroscopic interstitial wires and two non-hygroscopic interstitial wires 6 replace distribution and are wrapped with separator 3 at it, are provided with sheath 7 outside this separator 3.For example, be example with the cable of 2 * 2 * 0.37mm2, lead adopts 7 tin-coated copper conductors that diameter is 0.27mm, and insulating barrier 2 adopts polyethylene layers, and sheath 7 adopts pvc sheaths, and the outside diameter of cable is 9.8mm, cable weight is 98kg/km.It is thus clear that, above-mentioned hydraulic observation cable, the compactness of the construction of cable is relatively poor; Thereby cause the external diameter of cable bigger, therefore need the sheath of bigger external diameter, increased the material usage of sheath; Thereby increased production cost; And, the stranded complex procedures of this cable center line group, the structural stability of cable is relatively poor.
Summary of the invention
Problem to prior art exists the objective of the invention is to propose a kind of hydraulic observation cable, satisfying on the basis of cable performance, has reduced the outside diameter of cable, thereby has reduced the production cost of cable.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of hydraulic observation cable comprises two line groups, and each line group comprises two cores, is wrapped with screen at two cores; Two line groups are arranged in parallel, and ground wire is arranged in two slits between the line group, outside two line groups, is provided with sheath.
Preferably, be wrapped with the aluminium-plastic tape screen at two cores, and aluminium faces outwards.
Preferably, four cores in two line groups are formed positive tetrahedron, and ground wire is arranged in tetragonal center.
Preferably, said sheath is a pvc sheath.
Preferably, every stranded the forming of core multiple conducting wires, and at multiple conducting wires outerwrap polyethylene layer.
Preferably, every core is by seven stranded forming of tin-coated copper lead.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
A kind of hydraulic observation cable that the present invention proposes is satisfying on the basis of cable performance, and the structure of cable is tightr, thereby has reduced the outside diameter of cable, has reduced the external diameter of sheath accordingly, has reduced the material usage of sheath, has reduced the production cost of cable; In addition, reduced the stranded operation of cable center line group, made that the structure of cable is more stable.
Description of drawings
Fig. 1 is the cross-sectional view of a kind of hydraulic observation cable of proposing of the present invention.
Fig. 2 is the cross-sectional view of a kind of hydraulic observation cable of proposing of the present invention.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment:
As shown in Figure 2, the cross-sectional view of a kind of hydraulic observation cable that proposes for the present invention.
With reference to accompanying drawing, a kind of hydraulic observation cable that the present invention proposes comprises two line groups; Each line group comprises two cores, and wherein, every core is by multiple conducting wires 1 stranded forming; For example, every core can be by seven tin-coated copper leads, and at multiple conducting wires 1 outerwrap polyethylene layer 2; Be wrapped with aluminium-plastic tape screen 3 at two cores, and aluminium outwards faces; Two line groups are arranged in parallel, and ground wire 4 is arranged in two slits between the line group, outside two line groups, is provided with pvc sheath 5.
In a kind of specific embodiment, four cores in two line groups are formed positive tetrahedron, and ground wire is arranged in tetragonal center.
Above-mentioned hydraulic observation cable is satisfying on the basis of cable performance, and the structure of cable is tightr, thereby has reduced the outside diameter of cable, has reduced the external diameter of sheath accordingly, has reduced the material usage of sheath, has reduced the production cost of cable; In addition, reduced the stranded operation of cable center line group, made that the structure of cable is more stable.
Adopt the hydraulic observation cable of above-mentioned 2 * 2 * 0.37mm2, it is 0.27mm tin-coated copper conductor that conductor adopts 7 diameters, and insulating barrier adopts polyethylene layer, and sheath adopts pvc sheath, outside diameter of cable 6.3mm, and cable weight is 55kg/km.
In actual application, can carry out stranding by employing dish winch, before stranding, core is closely arranged according to demand, when stranding, just make cable core add certain pitch, reach the stable purpose of cable core structure.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obvious realization of the present invention does not receive the restriction of aforesaid way; As long as adopted the method design of invention and the various improvement that technical scheme is carried out; Or directly apply to other occasion without improving the design that will invent and technical scheme, all in protection scope of the present invention.
