High-performance underwater welding cable

Abstract

The invention discloses a high-performance underwater welding cable, comprising a cable core, wherein the cable core is twisted by two pairs of air pipes and a plurality of Kevlar filling ropes with different sizes; A waterproof inner protective layer is wrapped around the cable core, An inn conductor layer is arranged outside the waterproof inner protective layer, the inner conductor layer is first wrapped around the buffer type semiconducting resistance hose and then wrapped around the waterproof inner protective layer, the outer conductor layer is arranged outside the waterproof inner protective layer, the outer conductor layer is wrapped around the buffer type semiconducting resistance hose again, and the waterproof outer protective layer is squeezed outside the buffer type semiconducting resistance hose. The cable has high strength, good toughness, wear resistance, cold resistance, oil resistance, water resistance, aging resistance, weather resistance, high performance, but also has high water permeability, moisture permeability, wind resistance, antibacterial, mould resistance, anti-ultraviolet and energy release and many other excellent functions.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a high-performance underwater welding cable. Background technique [0002] Welding plays a very important role in modern industrial production. It is even more advantageous when manufacturing large structures or complex machine parts. According to statistics from industrially developed countries, steel used to manufacture welded structures accounts for about 70% every year. With the development of marine energy development projects, ocean transportation of ships, water rescue and other activities, large ships and marine steel structures such as submarine pipelines, offshore platforms, offshore airports, submarine cities, and sea-crossing bridges have emerged in large numbers. At the same time, underwater welding is also an important application technology in the national defense industry, so the demand and development of underwater welding wires are increasing day by day; at the s...

Problems solved by technology

At the same time, underwater welding is also an important application technology in the national defense industry, so the demand and development of underwater welding wires are increasing day by day; at the same time, the repair of related facilities is very important. The existing welding lines cannot meet the requirements of deep sea pressure and resistance impact force, and a single gas pipe cannot use multiple gases at the same time, so the new high-performance underwater welding cable is particularly important
