Abstract
The utility model relates to a water-proof magnetic measuring cable used for a ship, in particular to an improved water-proof magnetic measuring cable used for a ship, belonging to the cabal manufacturing technology. The improved water-proof magnetic measuring cable used for a ship comprises 6 to 18 insulating conductors, a braided shielding layer [5] and an oversheath [1] and is characterized in that a cable formed by all the insulating conductors is externally wrapped by a water blocking tape [4], the water blocking tape [4] is externally wrapped by the braided shielding layer [5], and the oversheath [1] is made from polyurethane. The utility model has good water resistance, wear resistance and salt fog corrosion resistance, small outside diameter, light weight and high strength and is not easily get mildewed and aged, thereby meeting the requirement of an underwater magnetic measuring system of the ship.
Description
Technical field
The utility model belongs to the cables manufacturing technology, relates to the improvement to underwater magnet measurement cable for ship.
Background technology
Along with the develop rapidly of sea, river and transport by sea industry and ocean engineering, all kinds of boats and ships and offshore oil platform etc. also will constantly increase, and various kinds of equipment improves day by day to the specification requirement of cable.Because the environment for use condition is harsher, then require cable security reliable, have good protection against the tide, sea water resistance salt air corrosion, a good electric and mechanical performance.Present underwater magnet measurement cable for ship, its structure is referring to Fig. 1, underwater magnet measurement cable for ship, it thoroughly does away with edge core, woven shield 5 and oversheath 1 by 6～18 and forms, insulated wire cores is made up of multifibres stranded conductor 2 and the insulating barrier 3 that is coated on multifibres stranded conductor 2 outsides, woven shield 5 is coated on the outside of the cable of all insulated wire cores compositions, and oversheath 1 is coated on the outside of woven shield 5.Its shortcoming is: the first, water resistance is poor.After water entered cable inside from the breakage of the slit of cable joint or oversheath 1, water will be along the cable longtitudinal dispersion, the insulation property of cable are descended greatly even lost efficacy.The second, oversheath 1 adopts elastomeric material, and external diameter is big, heavy, and intensity is low, wears no resistance, and salt fog resistance corrosivity is poor, and is mouldy easily; And it is aging easily.
Summary of the invention
The purpose of this utility model is: a kind of water proofing property, resistance to wear are proposed and salt fog resistance corrosivity is good, external diameter is little, in light weight, intensity is high, be difficult for mouldy and aging naval vessel waterproof magnet measurement cable, to satisfy under the naval ship water requirement of surveying magnetic system.
The technical solution of the utility model is: underwater magnet measurement cable for ship, it comprises that 6～18 thoroughly do away with edge core, woven shield 5 and oversheath 1, insulated wire cores is made up of multifibres stranded conductor 2 and the insulating barrier 3 that is coated on multifibres stranded conductor 2 outsides, woven shield 5 is positioned at the outside of the cable of all insulated wire cores compositions, and oversheath 1 is coated on the outside of woven shield 5; It is characterized in that,
(1) is surrounded with waterstop 4 in the cable outside that all insulated wire cores are formed, is coated with woven shield 5 in the outside of waterstop 4;
(2) said oversheath 1 adopts the polyurethane oversheath.
The utility model has the advantages that: water proofing property, resistance to wear and salt fog resistance corrosivity are good, and external diameter is little, and is in light weight, and the intensity height is difficult for mouldy and aging; Satisfied the requirement of surveying magnetic system under the naval ship water.One 7 core cable embodiment of the present utility model compares with existing product, reduced diameter more than 30%, weight saving more than 30%, improved water proofing property, resistance to wear and salt fog resistance corrosivity greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below the utility model is described in further detail.Referring to Fig. 1, underwater magnet measurement cable for ship, it comprises that 6～18 thoroughly do away with edge core, woven shield 5 and oversheath 1, insulated wire cores is made up of multifibres stranded conductor 2 and the insulating barrier 3 that is coated on multifibres stranded conductor 2 outsides, woven shield 5 is positioned at the outside of the cable of all insulated wire cores compositions, and oversheath 1 is coated on the outside of woven shield 5; It is characterized in that,
(1) is surrounded with waterstop 4 in the cable outside that all insulated wire cores are formed, is coated with woven shield 5 in the outside of waterstop 4;
(2) said oversheath 1 adopts the polyurethane oversheath.
Operation principle of the present utility model is: between cable and the sheath block water and have the performance of water-swellable, water entering section position space is filled up and airtight, the water that enters cable can vertically not flowed, thereby reaches the purpose of waterproof; The polyurethane oversheath has high abrasion, and the tearing toughness height is difficult for advantages such as mouldy.
Claims (1)
