Manufacturing process for deep sea water tight electric cable

Abstract

A method for manufacturing a deep-sea watertight cable belongs to the technical field of design and manufacture for the watertight cable structure in the field of marine technology, comprising eight process steps: the manufacture of conductive core wire cabling, the manufacture of refining films, the rubber slices, the manufacture of cable core sheaths, the die preheating, the coating of release agent, the core cable die filling and the installation and vulcanization; the invention designs a molding jacket vulcanization deep-sea watertight cable which is characterized by sea-water corrosion resistance, deep-sea pressure resistance, high-voltage resistance, and high electrical insulation in a deep-sea environment.

Description

Technical field: [0001] The invention relates to a manufacturing method of a deep-sea watertight cable, which is used in the manufacture of power and signal transmission cables for deep-sea exploration and operation technical equipment, and belongs to the technical field of design and manufacture of watertight cable structures in the field of marine technology. Background technique: [0002] At present, there are no power and signal transmission watertight cables used in deep-sea exploration and operation technology in China. In the past, in deep-sea exploration and operation, the deep-sea watertight cables used mainly depend on imports. The order cycle is long and the price is expensive. It belongs to developed countries. Embargoed products under technical blockade; deep-sea watertight cables imported from abroad mainly have two structural forms: deep-sea watertight ordinary cables and deep-sea buoyancy cables. The deep watertight buoyancy cables are mainly used for the tra...

Problems solved by technology

[0002] At present, there are no power and signal transmission watertight cables used in deep sea exploration and operation technology in China. In the past deep sea exploration and operation, the deep seatight cables used mainly relied on imports. The order cycle is long and the price is expensive, which belongs to the embargoed products of developed countries. The deep seatight cables imported from abroad mainly include deep seatight ordinary cables and deep sea buoyancy cables. Due to the particularity of the deep-sea exploration environment, the transmission of power and signals for the dial connector requires very strict requirements for deep-sea watertight cables. It is required that the structure of the deep-sea watertight cable itself must be able to withstand pressure in a deep-sea environment of 7,000 meters, seawater corrosion resistance, high voltage resistance and high insulation electrical performance; therefore, there is currently no deep-sea watertight cable that can meet the needs in China
