Example Embodiment

[0013] Below in conjunction with accompanying drawing, the present invention is described in detail:

[0014] As shown in Figure 1, the present invention is 19×2×0.5mm 2 Strong anti-electromagnetic interference sonar signal control flexible cable, the single core of the cable is 0.5mm 2 Tinned soft copper wire in line with national standards. The specific structure of the present invention includes a conductor cable core 1 with a soft tinned copper wire structure, and the conductor cable core is covered with an insulating layer 2 made of a non-polar polymer composite material. The insulating layer 2 is specifically a polyethylene elastomer insulating layer. Each two conductor cable cores 1 covered with the insulating layer 2 forms a twisted pair group, and each pair of twisted pair groups is coated with an insulating material (metal antioxidant + talcum powder) to form a shielding layer 3 . After the pair is formed into a cable, the polyester tape and the copper-plastic com...

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 [0001] The invention relates to a power device, in particular to a cable structure. Background technique [0002] With the increasing number of electrical equipment in our country, the requirements for high precision continue to increase, especially the requirements for non-interference and small attenuation required for railway signal transmission. Some original traditional signal and control cables cannot meet the requirements of use. Sonar signals are used as a monitoring function for the operation of electrical equipment, and are also widely used in target detection, classification, positioning and tracking under special circumstances; in addition, sonar technology is also widely used in torpedo guidance, mine fuze, and fish detection, marine Petroleum exploration, ship navigation, underwater operations, hydrographic survey and survey of seabed geology and landforms, etc. [0003] Sonar devices are generally composed of three parts: matrix, electronic c...
