Abstract
The utility model relates to a cable, in particular to a mineral insulated cable with a nickel core and an alloy sheath. The mineral insulated cable is mainly used for power transmission and distribution, i.e. signal transmission of control loop, in high-temperature or high-corrosion places, such as the petroleum, chemical engineering, metallurgy, ship, nuclear electricity and aerospace. The mineral insulated cable consists of a conductor, an insulation layer covering the conductor, and a sheath outside the insulation layer, wherein the conductor is a nickel core wire; the insulation layer is made of magnesium oxide; and the sheath adopts an 825 alloy sheath. The mineral insulated cable can be prevented from dialysis at high temperature so as to ensure the insulation performance and the use performance of the cable. In addition, the mineral insulated cable has little possibility of being damaged under the high-temperature and high-corrosion condition, so that the service life thereof is prolonged.
Description
Technical field
The utility model relates to a kind of cable, relates in particular to a kind of nickel core alloy sheath mineral insulated cable.The power transmission and distribution that is mainly used in high temperature or high corrosion place is the signal transmission of control loop, as high temperature, high corrosion fields such as oil, chemical industry, metallurgy, boats and ships, nuclear power, Aero-Space.
Background technology
The existing mineral insulated cable that has been widely used all is made up of inorganic matter.Be with copper as conductor, magnesium oxide as insulation, metal copper pipe a kind of cable as sheath.Main raw material(s): copper rod, magnesia powder, copper pipe.The construction of cable: sheath, seamless copper pipe; Insulation, magnesium oxide; Conductor, copper core.This cable technology parameter is as follows: rated voltage, 750V and following; Cable manufacture test voltage, underloading 2000V/min, heavily loaded 2500V/min; The long-term work temperature: the long-term work temperature is 70 ℃; The occasion long-term work temperature of touching at nobody is 105 ℃; In special high temperature occasion, the long-term work temperature can be at 250 ℃ and following.The technological deficiency of cable: because the conductor of mineral insulated cable is that metallic copper, oversheath are copper pipe, this just makes the working temperature of mineral insulated cable restricted, this cable the highest long-term bearing temperature is 250 ℃, osmotic phenomena can take place in the copper rod conductor under high-temperature condition, the insulation and the electrical property of cable have been reduced, in addition, perishable on copper sheath surfaces, deep-etching place such as sulfuric acid, hydrochloric acid, carbonic acid.
The utility model content
The purpose of this utility model provides a kind of nickel core alloy sheath mineral insulated cable, and it has good insulation performance performance and electric conductivity, also has high temperature resistant, corrosion resistant characteristics.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:
Nickel core alloy sheath mineral insulated cable, it by conductor, be coated on the outer insulating barrier of described conductor and be coated on the outer sheath of described insulating barrier and form, it is characterized in that: described conductor is the nickel heart yearn, and described insulating barrier is a magnesium oxide, and described sheath is 825 alloy sheaths.
Substituted copper core with the nickel heart yearn in the utility model technique scheme, made that the technical problem that dialysis at high temperature takes place for copper core in the prior art is solved.Because the fusing point of nickel is 1453 ℃, far above the fusing point of copper.And nickel just stability is higher a little less than than the metallicity of copper.825 alloy material fusing points are 1370～1400 ℃, and in various media such as sulfuric acid, phosphoric acid, alkali metal, good corrosion resistance is arranged, with 825 alloy sheath instead of copper sheaths, solved the problem that copper sheath is fragile under the high etching condition of high temperature, useful life is not high.
Therefore with nickel heart yearn instead of copper heart yearn, with 825 alloy sheath instead of copper sheaths, the problem of the electric property decline that the cable that can effectively solve prior art at high temperature causes because of oxide etch.
As preferably, described number of conductors is one, on the described axis that is arranged on nickel core alloy sheath mineral insulated cable.
As preferably, described number of conductors is a plurality of, and described conductor evenly distributes in insulating barrier.
As preferably, described a plurality of conductors are 2～10.
In sum, the utlity model has following beneficial effect:
1, since the fusing point of nickel far above the fusing point of copper, can solve copper rod with nickel heart yearn replacement copper core and insulation property and the serviceability problem that dialysis influences cable take place under hot conditions as conductor;
2, with 825 alloy sheath instead of copper sheaths, make the utlity model has under the high etching condition of high temperature not fragile, the effect that has prolonged useful life.
