The probe cable comprises a cable core, an isolating layer, a talcum powder layer, a water-resisting layer and an outer sheath layer, wherein the isolating layer, the talcum powder layer, the water-resisting layer and the outer sheath layer are mounted on the outer side of the cable core from the inside out; the cable core comprises a power cord, a video cable and a tensile cable; the power cord comprises a conductor, an insulating layer and a flame-retardant layer; and the insulating layer and the flame-retardant layer are mounted on the outer side of the conductor from the inside out. The probe cable has a and simple reasonable structure, is easy to produce and manufacture, excellent in service performance and extremely convenient in installation, use and maintenance, is wear-resistant, oil-proof, tensile, water-proof, corrosion-resistant, explosion-proof and flame-retardant, can simultaneously transmit video signals and electrical signals, meanwhile, has the advantages of stronger tensile and control strength, flexibility, small loss of insulating medium, low signal attenuation and superior comprehensive signal transmission capability, and is applicable to circuits of detection systems, such as nonmetallic mines, water wells, oil wells and the like, in which manual detection can is unavailable.

Description

Exploration cable

Technical field

The utility model relates to the cable technology field, is a kind of exploration cable.

Background technology

Along with the process of modernization construction is accelerated day by day, science and technology constantly promotes the prosperous and development of all trades, in recent years, the underground mine resource is constantly excavated and is deeply exploited and seems particularly active, novelly survey control to visit the equipment automaticity more and more higher, the new technology of exploration and new technology have obtained sufficient utilization and popularization; The particularly birth of down-hole computer network TT﹠C system has remedied the result that manually can't realize.The assurance system is normally stable, reliability service, then needs the high performance signal transmission line to cooperate with it and uses.Because the environment of down-hole is extremely abominable and complicated, common signal cable since be subjected to the infiltration of immersion oil, burn into, crooked, deflect, rub, wear out, the influence of own wt and external tensile force, greatly reduce the dielectric strength of cable, insulation dielectric loss is big, signal attenuation is big, cause to simulate a little less than the signal transmission, cause sensitivity reduction, distortion; Even, cause signal interruption because frequent the lifting causes cable to be broken.

Summary of the invention

The utility model provides a kind of exploration cable, has overcome the deficiency of above-mentioned prior art, and it can solve the problem that above-mentioned prior art exists.

The technical solution of the utility model is achieved like this: exploration cable, comprise core, separator, talcum bisque, water blocking layer and external sheath layer, and the core outside is equipped with separator, talcum bisque, water blocking layer and external sheath layer from the inside to the outside; Core comprises power line, video line and tensile cord, power line comprises conductor, insulating barrier and flame-retardant layer, the conductor outside is equipped with insulating barrier and flame-retardant layer from the inside to the outside, video line comprises conductor, video insulating barrier, composite shielding layer, metal screen layer and sheath, the conductor outside is equipped with video insulating barrier, composite shielding layer, metal screen layer and sheath from the inside to the outside, tensile cord comprises steel wire and lapping layer, and lapping layer is installed on the steel wire.

Above core also comprises gasket for packing, and this gasket for packing is the netted gasket for packing that blocks water of heat resistant type.

Above metal screen layer is the net metal screen that zinc-plated annealed copper silk is formed.

Above power line is provided with two.

Is that 0.25 to 0.41mm annealed copper skein silk closes and forms with upper conductor by diameter.

Above insulating barrier, video insulating barrier adopt the low-smoke halogen-free polyolefin material.

The utility model is rational in infrastructure simple, manufactures easily, and serviceability is good, and it is extremely convenient to install and use and safeguard, that product has is wear-resisting, oil resistant, tension, waterproof, performance such as anticorrosion, explosion-proof, fire-retardant, and realizes that the vision signal and the signal of telecommunication transmit simultaneously.Have stronger control intensity and the flexible characteristic of drawing simultaneously, the insulation lossy medium is little, and signal attenuation is low, and the integrated signal transmittability is superior, is applicable in the detection system circuit that nonmetallic ore, well, oil well etc. manually can't realize surveying to use.
