Abstract
The utility model relates to the field of special cables, in particular to a three-phase magnesium oxide metal sheathed super-long power cable, which solves the problems that the cable cannot be laid for a super-long distance or used for a long time in the severe environment in which corrosion and explosion, high temperature and high pressure, high humidity and high cold, impact shock, and tension and water simultaneously exist in China. The working ambient temperature of the cable can reach below 500 DEG C. The magnesium oxide metal sheathed super-long power cable is manufactured by connecting a metal conductor, magnesium oxide and a metal sheath with each other, wherein the metal conductor is uniformly extruded in the middle of the metal sheath through the magnesium oxide; the magnesium oxide is compactly distributed between the metal conductor and the metal sheath; and the cable is suitable for the super-long and narrow special environments of high temperature and high pressure, corrosion and explosion, icing and dewing, water and fire, and smash and tension. The cable is widely applied to manufacturing of magnesium oxide cable manufacturers, and can fill the blank of using and manufacturing of the cables for special environments and special super-long distance application in China.
Description
Technical field
The utility model relates to magnesium oxide special cable field, is specially a kind of three-phase oxidation magnesium metallic sheath overlength power cable.
Background technology
At present, the general three-phase oxidation magnesium metallic sheath power cable of Shi Yonging, its conductor area surpasses 3 * 10mm
2Hundred meters of cable length less thaies, complex manufacturing technology, production line is long above hundred meters, it is big to take the factory area, material, man-hour, waste was serious, and cost is higher, the production cycle is longer, overlength install connect lay numerous and diverse, accessory is more, its production technology is: be inserted in the magnesium oxide core by the good metallic conductor bar of calculating and penetrate in the heavy caliber metal tube again, make through bench tens of a bundle drawing repeatedly, annealing, moulding crops.Can't be at moisture-proof anticorrosive, explosion-proofly anti-pound, HTHP, high humidity are high and cold, overlength is laid long-term use in the impact endurance test shock, the simultaneous adverse circumstances of tension waterproof.
The inventor is inspired according to the welded pipe technological principle, has obtained brand-new breakthrough in process application, successfully develops three-phase oxidation magnesium metallic sheath overlength power cable.
The utility model content
The purpose of this utility model is to provide a kind of three-phase oxidation magnesium metallic sheath overlength power cable, solve domestic can't be high and cold at anticorrosion explosion-proof, HTHP, high humidity, in the impact endurance test shock, the simultaneous adverse circumstances of tension waterproof, overlength is laid long-term use problem, and its operating ambient temperature can reach below 500 degrees centigrade.
The technical solution of the utility model is:
Three-phase oxidation magnesium metallic sheath overlength power cable, this cable is bonded with each other by metallic conductor, magnesium oxide, metallic sheath and makes magnesium oxide metallic sheath overlength cable, metallic conductor is squeezed in the middle of the metallic sheath by magnesium oxide is well-balanced, and the magnesium oxide densification is distributed between metallic conductor and metallic sheath.
Three-phase oxidation magnesium metallic sheath overlength power cable, be that, high-frequency welding rolling through tubulation by the alloy tape forms tubular sheath, in this simultaneous oxidation magnesium moulding mixture through special equipment filling and fixing metal lead, through in the process of tubulation, lead is brought in the middle of the sheath by well-balanced extruding, the rolling shape operation that contracts in several roads of online process makes the magnesium oxide densification between conductor and sheath simultaneously, makes qualified overlength cable, can make the indefinite length cable according to customer requirements.
The beneficial effects of the utility model are:
1, cable security is reliable.Lay, do not have that pipe fitting joint, anticorrosion explosion-proof, HTHP, high humidity are high and cold, impact endurance test shock, tension waterproof, especially wear that the small-bore pipe overlength is laid, wireline environment is abominable according to different severe environments, overlength, need not external force introduce the purpose of bringing into, can directly insert, go directly, collect conveniently, time saving and energy saving, province's expense.This cable is applicable to using safely in the unconformable adverse circumstances of other cables.
2, cable life height.Because the cable cover(ing) main part adopts is that intensity is higher, physicochemical property preferably alloy material make, its superiority comes into plain view.
3, cable is easy to processing and manufacturing.Compare with the similar cable of domestic production, cable material, manufacturing and cost of labor obviously reduce, and the construction of cable is simple, material is general, be easy to processing and manufacturing.
4, the operability of cables manufacturing.Cable is a machining, and streamline production alleviates manual labor, ensures the quality of products safety, reliable, convenient; And some similar cables of domestic production do not have overlength, operate more loaded down with trivial details.
5, the special result of use of cable.Because the overlength performance of cable can reach desirable result of use in special environment for use.Can be widely used in that building, bridge, chemical industry, oil exploitation, coalfield inferior make directly air to open is adopted, clob system air to open is adopted, super dark oil well heating system air to open is adopted, and field such as military naval vessel, significant meaning is arranged.
6, cable economy.The utility model compares with the magnesium oxide cable that to have a cost low, material saves 1/3, also save 2/3 man-hour, produce area only take the production of original magnesium oxide cable 1/3, equipment cost is low, use that laid down cost is installed only is 1/2, installing space takies only is 1/3, especially in the narrow and small caliber of overlength, use in high and cold, the impact endurance test shock of anticorrosion explosion-proof, HTHP, high humidity, the simultaneous adverse circumstances of tension waterproof and install, all do not have comparativity with any cable.
The utility model can be widely used in the manufacturing of magnesium oxide cable.
In a word, the utility model has been filled up the blank that domestic special purpose cable is produced, can be high and cold at anticorrosion explosion-proof, HTHP, high humidity, overlength is laid long-term use in the impact endurance test shock, the simultaneous adverse circumstances of tension waterproof, remarkable advantages is arranged, in the middle of fields such as from now on national defence, chemical industry, oil, coal, skyscraper, large bridge, nuclear power, subway, have splendid market prospects.
