Abstract
A multilayer armored cable comprises an insulating cable core and external steel wire layers. The steel wire has no less than three layers and each layer has a different diameter. According to the multilayer armored cable provided by the utility model, the steel wire outside the insulating cable core adopts a multilayer structure of no less than three layers and the tensile strength of the multilayer armored cable is increased by 20% in comparison with that of the traditional cable with the same diameter; the steel wire layers with different diameters are adopted and the cable is multilayer armored such that the internal stress of the cable can be more balanced; and the cable is suitable for operation of complicated underwell environment and meanwhile service life of the cable is increased.
Description
Technical field
The utility model is involved in field of telecommunications cables, especially a kind of down-hole exploration cable.
Background technology
The important function of down-hole exploration cable is exactly to carry various downhole probes, transmit various signals between ground control system and the downhole instrument, obtain the depth location of down-hole information.It is as shown in Figure 1 to survey the construction of cable under the conventional well; Insulation cable core 3 outsides that are positioned at the center are provided with steel wire floor 2 and outer steel wire floor 1 two-layer steel wire; Anti-disconnected power is low, and internal stress is unbalanced, in the horizontal well of complicacy and super large inclined shaft, occurs easily breaking the generation that causes the underground work accident because of cable.And insulating material quality problems or heat resistance are relatively poor, cause insulating barrier aging very fast, and the cable core insulating capacity descends.
The utility model content
In order to overcome above-mentioned deficiency and the defective that exploration cable exists under the conventional well, the utility model provides a kind of anti-disconnected high multilayer armoured cable of power.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: the multilayer armoured cable, constitute by insulation cable core and outside steel wire floor, and the number of plies of steel wire floor is more than or equal to 3.
Said each layer of steel wire floor steel wire diameter difference.
Said insulation cable core comprises conduction cable core and insulating barrier, and the conduction cable core is a copper wire.
The multilayer armoured cable of the utility model, the outside steel wire floor of insulation cable core adopts the sandwich construction more than three layers, compares with the traditional cable of equivalent diameter, and its tensile strength increases about 20%; Adopt the steel wire of different-diameter, the armouring of multilayer number, thus make the internal stress of cable can be balanced more; Can adapt to the operation of down-hole complex environment, increase the useful life of cable simultaneously.
Description of drawings
Fig. 1 is the structure chart of traditional cable.
Fig. 2 is the structure chart of the multilayer armoured cable of the utility model.
Embodiment
The multilayer armoured cable structure of the utility model is as shown in Figure 2, is made up of insulation cable core 3 and outside steel wire floor 4, and the sandwich construction that steel wire floor 4 adopts more than three layers is compared with the traditional cable of equivalent diameter, and its tensile strength increases about 20%; Adopt the steel wire of different-diameter, the armouring of multilayer number, thus make the internal stress of cable can be balanced more; Can adapt to the operation of down-hole complex environment, increase the useful life of cable simultaneously.Insulation cable core 3 comprises conduction cable core and insulating barrier, and the conduction cable core adopts the coiling of high-quality copper wire to form.Traditional insulating material quality problems or heat resistance are relatively poor; Cause insulating barrier aging very fast, the cable core insulating capacity descends, and the insulating barrier of the utility model cable adopts the fluoroplastics, polypropylene of electric property and better mechanical property, too material such as fluon is processed; Characteristic with oil resistant air water and soda acid salt corrosion; Increase the service life greatly, be applicable in the horizontal well of complicacy and super large inclined shaft and use, can reduce because of cable and break the accident that takes place.
