Problems solved by technology

Its disadvantages are: both the insulating layer 3 and the outer sheath 6 are made of rubber material, the outer diameter is large, the weight is heavy, the strength is low, the wear resistance is poor, the salt spray corrosion resistance is poor, and it is easy to mold; and it is easy to age. Once the rubber is aged, it is waterproof. The performance is greatly reduced and cannot meet the requirements of the ship's underwater magnetic measurement system

Abstract

The invention provides an underground magnetic-measuring cable used for ships, belonging to the cable manufacture technique, and relating to improvement to the underground magnetic-measuring cable used for the ships. The underground magnetic-measuring cable comprises 6-18 insulated wire cores, a knitting shielding layer (5) and an external protection sleeve (6); the underground magnetic-measuring cable is characterized in that the center of the insulated wire core is provided with an aramid-reinforced filling core (1); the insulated layer (3) adopts a thermal-plastic vulcanized rubber insulation layer; a waterproof belt (4) is enwound on the external surface of the cable consisting of all the insulated wire cores; the external surface of the waterproof belt (4) is wrapped with the knitting shielding layer (5); the external protection sleeve (6) adopts a polyurethane external protection sleeve.

Description

technical field [0001] The invention belongs to the cable manufacturing technology and relates to the improvement of underwater magnetic measuring cables for ships. Background technique [0002] With the rapid development of river, ocean and ocean transportation industries and marine engineering, various types of ships and offshore oil platforms will also continue to increase, and the technical requirements for cables for various types of equipment are increasing. Due to the harsh environmental conditions of use, the cables are required to be safe and reliable, long in life, small in size, light in weight and low in price, and have excellent temperature resistance, fire resistance, flame retardancy, oil resistance, moisture resistance, sea water resistance, excellent electrical and mechanical properties Wait for the request. The current underwater magnetic measuring cable for ships, its structure can be found in figure 1 , Underwater magnetic measuring cable for ships, it ...
