High-tensile-strength signal transmission drum cable

Abstract

The invention discloses a high-tensile-strength signal transmission drum cable. The high-tensile-strength signal transmission drum cable comprises cable cores which are formed by stranding a plurality of insulation wire cores. Filing layers are arranged at gaps of the cable cores. A polyester tape is overlapped outside the cable cores in a lapping mode. A shielding layer is arranged outside the polyester tape in a lapping mode. An outer sheathe is arranged outside the shielding layer in a pressing wrapping mode. A stainless steel armor layer is woven on the outermost layer of the cable cores. A drainage line is arranged in the shielding layer in a flat dragging mode. The insulation wire cores are composed of reinforcing cores, tinned copper wire weaving layers and insulation layers, wherein the tinned copper wire weaving layers and the insulation layers are arranged outside the reinforcing cores in a pressing wrapping mode. The high-tensile-strength signal transmission drum cable has the advantages of resisting acid and alkali, oil, wear and aging, and being waterproof and long in service life, has the flame-retardant function, and can be widely applied to tensile and signal transmission control systems required by large bank cranes in ports, rail type cranes, iron and steel plant discharging cars and other heavy type haulage equipment.

Description

[0001] technical field [0002] The invention relates to the field of power cables, in particular to a high tensile signal transmission reel cable. Background technique [0003] At present, with the improvement of people's living standards and the acceleration of my country's social and economic construction, high-tensile signal transmission reel cables are widely used in port large-scale shore cranes, rail cranes, steel plant unloading vehicles and other heavy handling equipment, etc. The required tensile and signal transmission control system. Due to the particularity of the reel cable, many lifting equipment manufacturers currently have very strict requirements for the signal system connection line. The accuracy and sensitivity of signal transmission must be guaranteed, and it must have very high anti-interference shielding performance. The harm caused by the inaccurate transmission of the instrument signal caused by interference is very great. Therefore, the anti-interfe...

Problems solved by technology

Due to the particularity of the reel cable, many lifting equipment manufacturers currently have very strict requirements for the signal system connection line. The accuracy and sensitivity of signal transmission must be guaranteed, and it must have very high anti-interference shielding performance. The harm of inaccurate transmission of instrument signals caused by interference is very great, so the anti-interference characteristics of the reel cable are extremely demanding

[0004] The development of domestic high tensile signal transmission reel cables started late, and the technical level of various manufacturers is uneven. In addition, in recent years, the requirements for tensile strength and signal transmission have become higher and higher, resulting in many manufacturers being unable to design due to limited technical strength. , Produce high tensile signal transmission reel cable products that meet technical requirements

And the production process has the following problems: 1, the processing capacity is large, and the production cost is high

2. It is not conducive to laying and management, and the risk factor is large

3. It is not conducive to the assembly of finished products, and the production cycle is long

4. Large volume, waste of materials
