Compared with the prior art, the shielded cable has the advantages that 1, the design is reasonable, and the anti-interference performance is good; 2, the anti-oxidation ability is high, the service life is long, frequent maintenance is avoided, and the hydraulic project detection cost is reduced; and 3, the shielded cable has good physical and mechanical performance and excellent waterproofness and weatherability, and is particularly suitable for being used in the field of hydraulic project monitoring.
Description
Technical field
The utility model relates to water conservancy project checkout equipment technical field, especially relates to a kind of water conservancy project and monitors five core duplex sheath watertight type shielded type cables.
Background technology
Along with the development of water conservancy project monitoring instrument and the enforcement of monitoring automation system, increasing hydraulic engineering has been buried more safety monitoring instrument underground for guaranteeing safety.The safety monitoring instrument can adopt the material of waterproof, corrosion resistance to make, because of it does not move at any time, so it can not produce destruction because of being corroded.But be used for that transducer is connected with monitoring system, matching used cable just becomes the monitoring design needs the emphasis taken precautions against.Because the specific operational environment of hydraulic engineering, fail safe etc. require water conservancy project monitoring cable not only will have the electrical characteristic of transmission signal specific, also will have long-time stability and water pressure resistance under the water conservancy project environment, and characteristics such as ageing-resistant performance is good.
Existing cable is unstable properties under the water conservancy project environment, and resistance to water is also very poor, often because of the destruction of cable or be corroded, need employ bigger Financial cost and keep in repair.Therefore pressing for the good cable of a kind of electrical characteristic carries out the connection of relevant device.This cable should be worked under the water conservancy project environment steadily in the long term, water pressure resistance, and ageing-resistant performance is good.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, Chinese patent literature discloses a kind of double sheath soft cable [publication number: CN02109610.4], the cable inner sheath adopt contain chlorosulfonated polyethylene rubber and contain neoprene and after mechanical mixture, make.Oversheath protection inner sheath of the present invention makes inner sheath not be subjected to extraneous mechanical damage, prevents the effect of extraneous various chemical factor corrosion and aging condition simultaneously.The somebody has invented a kind of hydraulic observation with two core signal shielding cables [application number: CN200920037931.3], comprise that cable core, insulating barrier, aluminium foil split screen, ground wire, aluminium foil always shield, sheath is formed, cable core adopts stranded tinned copper wire, insulating barrier adopts high-density polyethylene material, divide shielding to adopt vertical alclad paper tinsel, sheath material adopts polyurethane material.
Though such scheme has improved performance to a certain extent, still exist cost cost height, structure is stable inadequately, and weatherability and resistance to water are not high, and electric property is difficult to the satisfied technical problems such as required of using.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides a kind of reasonable in design, simple in structure, the job stability height, and good weatherability, five core duplex sheath watertight type shielded type cables are monitored in the water conservancy project that electric property is high.
For achieving the above object, the utility model has adopted following technical proposal: five core duplex sheath watertight type shielded type cables are monitored in this water conservancy project, comprise five cable cores that surround together, periphery at every cable core is arranged with insulating case respectively, it is characterized in that this cable also comprises the separation sleeve of the cable core encirclement that can will surround together, is filled with filler in separation sleeve, be with the hydrophobicity inner sheath in the periphery of separation sleeve, be with corrosion-resistant oversheath in the periphery of hydrophobicity inner sheath.The filler here is non-moisture absorption filler, constitutes to have the cable of resistance to pressure, sealing and water proofing property preferably under the cooperation of hydrophobicity inner sheath and corrosion-resistant oversheath.
Monitor in the five core duplex sheath watertight type shielded type cables in above-mentioned water conservancy project, described cable core is made by tinned copper wire.
Monitor in the five core duplex sheath watertight type shielded type cables in above-mentioned water conservancy project, described separation sleeve is formed by the coiling of plastic-aluminum band.
As another kind of scheme, to monitor in the five core duplex sheath watertight type shielded type cables in above-mentioned water conservancy project, described separation sleeve is the copper mesh housing.
Monitor in the five core duplex sheath watertight type shielded type cables in above-mentioned water conservancy project, described insulating case is made by ethylene-propylene rubber.
Compared with prior art, the advantage that five core duplex sheath watertight type shielded type cables are monitored in this water conservancy project is: 1, reasonable in design, and good in anti-interference performance.2, oxidation resistance is strong, and long service life is avoided frequent maintenance, has reduced water conservancy project and has detected cost.3, have good physics and mechanical performance, good water proofing property and weatherability, be particularly suitable for water conservancy project monitoring field and use.
