Abstract

The utility model proposes a kind of wrapped submarine cable, comprise submarine cable core and wire armour, be surrounded with one deck or two layers of polypropylene fiber anticorrosion adhesive tape in the outer overlap of wire armour, the lapping direction of polypropylene fibre anticorrosion adhesive tape is contrary with wire armouring direction.The utility model adopts polypropylene fibre anticorrosion adhesive tape to do serving on extra large cable, has both eliminated this road of hot pitching operation not environmentally, adds again the wear strength of serving when not increasing operation (nonwoven fabrics) newly.

Description

A kind of wrapped submarine cable
Technical field
The utility model belongs to submarine cable manufacturing technology.
Background technology
Current most submarine cable armoring mainly armouring+serving once completes, see Fig. 1, cable core 1 generally includes the formations such as conductor 11, conductor screen 12, insulation 13, insulation shielding 14, semiconductive water-blocking buffer layer 15, lead sheath 16, PE sheath 17, its outer armour is generally wire armour 2, serving adopts pitch 4, PP rope 5 and nonwoven fabrics 6 usually, hot pitching is to play the effect preventing seawater corrosion, and serving comprises polypropylene winding rope (PP rope), the rope made of hemp, nonwoven fabrics.But this structure has the following disadvantages: one be hot pitching operation extremely not environmentally; Two is that the polypropylene winding rope, the rope made of hemp etc. of serving easily wear and tear going on board, in unwrapping wire process, rupture, and in order to prevent loose, the damage of rope, also wants wrapped nonwoven fabrics outside some Hai Lan manufacturers.
Summary of the invention
The purpose of this utility model is to propose a kind of wrapped submarine cable; use a kind of existing pitch antisepsis; the wrapped band of the effect of the protection submarine cables such as polypropylene winding rope, the rope made of hemp can be had again concurrently; reduce manufacturing procedure; overcome the hot pitching operation problem extremely not environmentally that prior art exists, and strengthen the antibody Monoclonal ability of serving.
The technical solution of the utility model is as follows:
A kind of wrapped submarine cable, comprise submarine cable core and wire armour, it is characterized in that: be surrounded with one deck or two layers of polypropylene fiber anticorrosion adhesive tape in the outer overlap of wire armour, the lapping direction of polypropylene fibre anticorrosion adhesive tape is contrary with wire armouring direction.
The wrapped rate of putting up of described overlap controls 20% ~ 50%.
Polypropylene fibre anticorrosion adhesive tape is the environmental friendly, anti-corrosive product that a kind of novel pollution-free, nothing endanger, be widely used in the plumbing in oil, natural gas, chemical industry, urban construction, the outer anticorrosion and recovery project of oil gas, coal gas conveying steel pipe and steel buried storage tank body.Polypropylene fibre anticorrosion adhesive tape is bilateral structure, and internal layer is bitumen layer, and skin is polypropylene fibre layer, and thickness is generally 1.5mm, and density is 1.2g/cm 2, there is the characteristics such as easy to use, shock resistance, ageing-resistant, stretch-proof, UV radiation, adhesion strength are high.
The utility model adopts polypropylene fibre anticorrosion adhesive tape to do serving on extra large cable, has both eliminated this road of hot pitching operation not environmentally, adds again the wear strength of serving when not increasing operation (nonwoven fabrics) newly.
Accompanying drawing explanation
Fig. 1 is the sectional view of existing submarine cable;
Fig. 2 be the utility model proposes the sectional view of submarine cable.
Embodiment
See Fig. 2, the submarine cable that the utility model proposes comprises cable core 1 and wire armour 2 and polypropylene fibre anticorrosion adhesive tape 3.Specific practice is: submarine cable core 1 is after Sheathed metal silk layer 2, overlapping wrapped one deck or two layers of polypropylene fiber anticorrosion adhesive tape 3 on winding machine, lapping direction is contrary with steel wire armoured direction, the overlapping wrapped rate of putting up controls 20% ~ 50%, closely wrapped along extra large cable direction of advance on winding machine.
