Underwater oil-filled cable and manufacturing method thereof

Abstract

The invention provides an underwater oil-filled cable and a manufacturing method thereof. The underwater oil-filled cable mainly comprises watertight plugs, a lead, a plastic hose, compensation oil and clamping devices; the lead is wrapped inside the underwater oil-filled cable by the plastic hose to realize the isolation of the inside from water; and the pressure difference of the inside and the outside caused by the water pressure is balanced by the compensation oil in the plastic hose. When the underwater oil-filled cable is manufactured, the lead is cut off according to the required length of the cable and the cut cable is enabled to penetrate into the plastic hose; the corresponding watertight plugs are respectively welded at two ends of the lead; after the welding is finished, one end of the lead is clamped by using the clamping devices such as AB adhesive and a hoop; then the compensation oil is filled into the plastic hose from the other end of the lead; and after the plastic hose is fully filled with the compensation oil, the plastic hose is clamped by the clamping devices, and finally the whole oil-filled cable is manufactured. The underwater oil-filled cable has the advantages of low price, great underwater work depth, simpleness and convenience in manufacture, safety and reliability in use and low possibility of being scratched.

Description

technical field [0001] The invention relates to an underwater cable, in particular to an underwater oil-filled cable and a related manufacturing method, which are mainly used for the transmission of electric power and signals between sealed compartments in marine underwater measuring instruments and engineering equipment. Background technique [0002] Ocean research, development and utilization are inseparable from ocean survey instruments and ocean engineering equipment. Due to the particularity of the marine environment, every 10 meters of water depth will increase the pressure by 1 atmosphere. At the same time, seawater is also a good conductor. Therefore, measuring instruments and engineering equipment used in the air must solve the problem of pressure resistance and sealing when used in seawater. At the same time, because the deeper the seawater, the greater the pressure, so marine surveying instruments and marine engineering equipment cannot be made too large. They are...

Problems solved by technology

Due to the complicated production process, this kind of cable needs to be vulcanized many times, resulting in high price, long delivery cycle and inconvenient maintenance.

At the same time, because the entire cable is a thin rubber product, the outer skin is easily scratched by hard objects or punctured by sharp objects during use, and it is not easy to detect. After being used in the water, water will enter the interior of the cable along the damaged opening, resulting in a short circuit or even an accident. ACCIDENT
