Abstract
The invention discloses a sonar signal control flexible cable with high electromagnetic-interference resistance. The sonar signal control flexible cable is characterized by comprising conductor cores having flexible tinned copper wire structures. Each conductor core is covered with an insulating layer made of a non-polar high-polymer composite material, each two conductor cores covered with the insulating layers form a stranded pair, each stranded pair is covered with a shield layer, and two layers of stranded pairs are arranged along a circumference direction of the stranded pair in the center as a lining core. The cable formed of the multiple stranded pairs is covered with a braided shield layer, the braided shield layer is covered with a copper-plastic composite belt shield layer, the copper-plastic composite belt shield layer is covered with an outer braided shield layer, and the outer braided shield layer is provided with sheath. The sonar signal control flexible cable is reasonable in structure, low in density, light, flame-retardant and environment-friendly. Performance of environmental protection, convenience in installation and the like of the cable is improved, effective transmission of the cable is guaranteed, and the cable can work normally even in strong electromagnetic fields.
Description
Technical field
The present invention relates to a kind of power equipment, specifically a kind of construction of cable.
Background technology
Increasing along with China's electric equipment, the improving constantly of high-accuracy requirement, particularly the railway signal delivery request is noiseless, and it is little to decay etc., and requirement improves constantly.More original classical signal, control cables be not to satisfy instructions for use.Sonar signal is as the supervision effect of electric equipment running, also is widely used in particular cases target and surveys, classifies, locates and follow the tracks of; In addition, sonar technique also is widely used in torpedo guidance, sea mine fuze, and the exploration of the locating fish, offshore oil drilling, marine navigation, underwater operation, hydrographic survey and submarine geology and geomorphology etc.
Sonar equipment generally is comprised of basic matrix, electronics rack and auxiliary equipment three parts.Basic matrix is arranged in a combination with certain geometric figure by underwater acoustic transducer, and its profile is generally sphere, cylindricality, plate shaped or alignment row, has to receive dividing of basic matrix, transmitter battle array or transmitting-receiving unification basic matrix.Electronics rack generally has the subsystems such as emission, reception, demonstration and control.The devices such as auxiliary equipment comprises power-supply device, stube cable, junction box and repeater, the lifting, revolution, pitching, the folding and unfolding that match with the transmission control of sonar transducer array under water, pulls, hangs, input, and sonar dome etc.Its specification requirement of the stube cable of using as auxiliary equipment is high, and manufacture difficulty is large, dependence on import always, and fire-retardant, waterproof, overcurrent proof magnetic disturbance performance and good not.
Summary of the invention
Purpose of the present invention is exactly for the deficiencies in the prior art, and the anti-electromagnetic interference sonar signal of a kind of sound intensity control flexible cable is provided, and has the performances such as good fire-retardant, waterproof, overcurrent proof magnetic disturbance.
The technical solution used in the present invention is as follows:
A kind of strong anti-electromagnetic interference sonar signal control flexible cable, it is characterized in that it includes the conductor cable core that adopts soft tinned copper wire structure, described conductor cable core is surrounded by the insulating barrier that adopts the non-polar high polymer composite material to make outward, two conductor cable cores that are surrounded by described insulating barrier form the pair twist group, every pair of pair twist group is equipped with screen outward, be positioned at bosom place and as bedding core hinge group circumferencial direction be provided with two layers to the hinge group, the cable that described a plurality of pair twist group forms is provided with woven shield outward, described woven shield is provided with the compound copper-plastics band screen outward, the compound copper-plastics band screen is provided with outer woven shield outward, and described outer woven shield is provided with oversheath outward.
Described woven shield is that count is not less than 80% zinc-plated soft copper silk braid.
Described insulating barrier is the polyethylene elastomer insulating barrier.
The oversheath of described cable adopts the rubber-plastic elastomer material of modification to make.
Beneficial effect of the present invention has:
Rational in infrastructure, its pair twist group structure wire of arranging more closely, and insulating sheath material has all adopted the rubber-plastic elastomer material of novel modification, density is little, and is lightweight, the cable new material of flame-proof environmental protection, improved the environmental protection of cable and the performances such as convenient have been installed, the screen of cable is that compound copper-plastics band adds braid shielded, has guaranteed effective transmission performance of cable, has guaranteed that cable also can work under strong-electromagnetic field.Sheath adopts rubber-plastic elastomer material to have fire-retardant, wear-resisting, oil resistant, the performance such as anti-aging, satisfies the cable instructions for use.
