The two-core signal shielding cable is particularly suitable for a two-core bowstring sensor signal transmission cablefor hydraulic observation, has good electrical character, self softness, easy bending, good water pressure resistance and better water resistance, and can be adapted to the environmental requirementof water conservancy projects.
Description
Technical field
The utility model relates to a kind of hydraulic observation with two core signal shielding cables, belong to the signal cable field, be particularly useful for hydraulic observation with two core string type sensor signal-transmitting cables, can be widely used under the water conservancy project environment, have excellent water tolerance and electrical characteristic, can adapt in the hydraulic engineering environment.
Background technology
Follow the progressively propelling of this modernization, science and technology is more and more flourishing, related field is also more and more broader, the field that did not relate in the past or seldom related to, progressively begun to relate to exploration now, thinking more in the past also has related in the field of comparison danger and the inaccessible field of scientific and technological at that time degree now.
Along with the development of water conservancy project detecting instrument and the enforcement of monitoring automation system, increasing hydraulic engineering is for guaranteeing safety, buried more safety detecting instrument underground, safety detecting 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 the hydraulic observation 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, resistance to water is also very poor, often because of the destruction of cable or be corroded, need employ bigger Financial cost keeps in repair, therefore it is good to press for a kind of electrical characteristic, long-time stability under the water conservancy project environment and water pressure resistance, the cable that ageing-resistant performance is good carries out the connection of relevant device.
The utility model content
The utility model has been done technological improvement at needs in the specific water conservancy project environment and the deficiency in the existing technology to existing cable technology, and it is good to have electrical characteristic, long-time stability under the water conservancy project environment and water pressure resistance, the characteristic that ageing-resistant performance is good.
In order to solve the defective under the above-mentioned specific environment, the utility model provides a kind of hydraulic observation with two core signal shielding cables, comprise that specifically cable core, insulating barrier, aluminium foil split screen, ground wire, aluminium foil always shield, restrictive coating 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, described cable is by two pairs of cable core runs parallel, adopt line that split screen is independently coated respectively, closely surrounded in the total screen of aluminium foil by gummed behind the laying ground wire between two pairs of cable cores.
Further, described cable core adopts stranded tinned copper wire, and good in oxidation resistance is easy to welding, and can guarantee the softness and the resistance to bend(ing) energy of lead, unite in the gummed mode behind every pair of cable core overcoat insulating barrier.
Further, described insulating barrier adopts high-density polyethylene material, has not only guaranteed the signal transmission property of cable, and the insulation resistance height, can improve like this because the low excessively signal that causes of cable resistance disturbs.
Further, described aluminium foil split screen adopts line to split screen, is coated on outside every pair of cable core, adopts vertical alclad paper tinsel mode, and good, the anti-tampering property of shield effectiveness is good, and the signal transmission is better.
Further, described restrictive coating material selection polyurethane material, hydrolytic resistance is good, good mechanical property, good corrosion resistance has improved the environmental resistance of cable, and restrictive coating is coated on outside the total screen of aluminium foil, and the total screen of aluminium foil is coated on outside two pairs of cable cores and the ground wire.
The utility model has the following advantages with respect to existing technology:
1, have good flexibility and resistance to bend(ing) energy: conductor adopts stranded tinned copper wire, and good in oxidation resistance is easy to welding, and can guarantee the softness and the resistance to bend(ing) energy of lead;
2, antijamming capability is strong: high-density polyethylene material is adopted in insulation, has not only guaranteed the signal transmission property of cable, and the insulation resistance height, can improve like this because the low excessively signal that causes of cable resistance disturbs;
3, shield effectiveness is good: line adopts vertical alclad paper tinsel mode to split screen, and good, the anti-tampering property of shield effectiveness is good, and the signal transmission is better;
4, environmental resistance is good: sheath material selection polyurethane material, and hydrolytic resistance is good, good mechanical property, good corrosion resistance has improved the environmental resistance of cable.
5, anti-hydraulic pressure performance is good: water pressure resistance is good, and the better waterproof energy is arranged, and can adapt to the environmental requirement of hydraulic engineering.
