Embodiment Construction

[0013] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0014] Such as figure 1 As shown, a reinforced sensor cable includes a wire core, an inner shielding layer 2 covering the outside of the wire core, an outer shielding layer 3 covering the outside of the inner shielding layer 2, and an outer sheath covering the outside of the outer shielding layer 3 4. The wire core is composed of an air duct 12, a copper core and a copper core reinforcement 14. Among them, there are four copper core reinforcements 14, and the number of copper cores is four. The copper core reinforcement 14 and the copper core are arranged alternately, and Surrounding the outer periphery of the air duct 12 , the copper core is composed of a copper wire 11 and an insulating layer 13 covering the outs...

Abstract

The invention relates to a reinforced type sensor cable which includes a wire core, an inner shielding layer wrapped outside the wire core, an outer shielding layer wrapped outside the inner shielding layer and an outer protective layer wrapped outside the outer shielding layer. The wire core includes an airway tube, copper cores and copper core reinforcers, wherein the number of the copper core reinforcers is four, and the number of the copper cores is four. The copper core reinforcers and the copper cores are arranged in an intersected mode, and encircle the periphery of the airway tube. The copper cores are formed by a copper conductor and an insulating layer wrapped outside the copper conductor. The reinforced type sensor cable has the advantages of being uniform in electromagnetic field distribution, little in mutual interference, and good in electromagnetic compatibility.

Description

technical field [0001] The invention relates to a cable, in particular to a reinforced sensor cable, which belongs to the technical field of cable manufacturing. Background technique [0002] The cable is laid in deep wells, mines, reservoirs and other environments where it is difficult to observe pressure changes. The lower end of the cable is connected to the pressure sensor, differential pressure transmitter, etc., and the upper end of the cable is connected to the computer of the ground measurement and control system. Pressure changes. Because the working conditions and environment of oil wells, mines and other occasions are particularly harsh, in addition to requiring the cable to transmit current information and directly transmit pressure displacement information, it must also have extremely high mechanical tensile strength and excellent electromagnetic field interference performance. Therefore, the designed cable structure should be symmetrical, with excellent streng...
