Polar cold-resistant flexible cable and its manufacturing process

Abstract

The invention provides a polar cold-resistant flexible cable and a manufacturing process thereof. The polar cold-resistant flexible cable includes an inner conductor, which is formed by twisting a copper-magnesium alloy wire and a silver-plated copper wire; an insulating layer arranged on the outer side of the inner conductor ; an outer conductor layer arranged on the outside of the insulating layer, wherein the outer conductor layer is a silver-plated aramid braid; a metallized carbon fiber shielding layer arranged on the outside of the outer conductor layer; an outer shield arranged on the outside of the metallized carbon fiber shielding layer A sleeve and a braided sleeve protective layer arranged on the outer side of the outer sheath. The polar cold-resistant flexible cable can meet the requirements of load-bearing, tensile resistance, anti-interference, bending resistance, flame retardant, wear resistance, high and low temperature resistance, extreme harsh environment resistance, small outer diameter, current carrying, and communication. On the winch in the ice drilling cavity, it can be used repeatedly in a small space, and because the cable has the function of infrared radiation self-heating, it can accelerate the melting of the ice surface of the outer layer of the drilling tool, accelerate the sampling progress, and improve the reliability of equipment operation. .

Description

technical field [0001] The invention relates to a polar cold-resistant flexible cable and a manufacturing process thereof, and belongs to the technical field of cables. Background technique [0002] Industrial civilization has greatly enriched human material production. However, human activities, such as ocean hunting, natural resource exploitation, industrial carbon dioxide and other gas emissions exceeding the standard, have caused global warming, thus causing a large number of glaciers (including polar glaciers) to melt. The polar environment has formed many glaciers, which not only store a large amount of water resources, but also freeze millions of microorganisms per square meter of ice. In recent years, all countries have strengthened the research on glaciers, glacial lakes, and subglacial lakes. Through sampling, the status and changes of polar water resources and microorganisms can be accurately analyzed. [0003] After research and investigation, the average thick...

Problems solved by technology

However, the outer diameter of the traditional winch cable is large, and the size of the required winch equipment is also large, which cannot meet the requirements of equipment miniaturization in extreme environments such as Antarctic scientific research.

At the same time, traditional cables for winches are generally used in conventional environments, and their functions are relatively single, which cannot meet other requirements such as communication, and the reliability of use in extreme environments cannot be guaranteed.
