Description
Technical field
The utility model belongs to cable technology field, refers in particular to a kind of waterproofing type wire armoring submarine cable.
Background technology
Development along with marine cause, ocean engineering construction is more and more, the use amount of submarine cable certainly will be also increasing, but because the invasion and attack of the acid containing in seawater, alkali, salt pair submarine cable are larger, therefore, the design of the water-tight corrosion-proof of submarine cable is extremely important, especially for continent and island, and the cable of the cables such as island and island and signal transmitting effect.
Summary of the invention
The purpose of this utility model be to provide a kind of block water corrosion resistant and conduct electricity very well, waterproofing type wire armoring submarine cable that tensile strength is high.
The purpose of this utility model is achieved in that
Waterproofing type wire armoring submarine cable, in three circumferential outsides uniform and the cable main line that is mutually abutted against, be disposed with from inside to outside modification waterproof PE sheath, wire armoring and oversheath, in hole between the inner surface of the outer surface of every cable main line and modification waterproof PE sheath, be provided with inserts, described cable main line is for being disposed with from inside to outside conductor shield at the outer surface of water-blocking conductor, XLPE insulating barrier, insulation screen, copper strips layer, modification waterproof semiconductive PE sheath, described water-blocking conductor is by stranded the forming of multiply electrician copper free wire, in the stranded space of monofilament of adjacent electrician's copper free wire, be provided with the water-proofing powder of water-swellable.
Above-mentioned conductor shield, insulation screen are semiconductive TPO plastics and make.
Above-mentioned modification waterproof semiconductive PE sheath is that semiconductive nylon tape is made.
To be polyvinyl chloride or poly-hydro carbons make as PP, PE, PVC and PB plastics above-mentioned oversheath.
Above-mentioned inserts is waterproofing rope.
Accompanying drawing explanation
Fig. 1 is transverse sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to Fig. 1:
Waterproofing type wire armoring submarine cable, in three circumferential outsides uniform and the cable main line that is mutually abutted against, be disposed with from inside to outside modification waterproof PE sheath 8, wire armoring 9 and oversheath 10, in hole between the inner surface of the outer surface of every cable main line and modification waterproof PE sheath 8, be provided with inserts 7, described cable main line is for being disposed with from inside to outside conductor shield 2 at the outer surface of water-blocking conductor, XLPE insulating barrier 3 (making with crosslinked polyethylene), insulation screen 4, copper strips layer 5, modification waterproof semiconductive PE sheath 6, described water-blocking conductor is by multiply electrician copper free wire 1 stranded forming, in the stranded space of monofilament of adjacent electrician's copper free wire 1, be provided with the water-proofing powder 11 of water-swellable, conduct electricity very well.
Above-mentioned conductor shield 2, insulation screen 4 are semiconductive TPO plastics and make.
Above-mentioned modification waterproof semiconductive PE sheath 6 is made for semiconductive nylon tape, semiconductive and three cable main lines of modification waterproof semiconductive PE sheath 6 are abutted against mutually, can, so that the outer surface of three cable main lines is idiostatic, prevent the high infringement to cable causing of local potential.
Above-mentioned oversheath 10 is for to make as PP, PE, PVC and PB plastics with corrosion resistant polyvinyl chloride or poly-hydro carbons, and its corrosion resistance and good, is mainly used in acid and alkali-resistance and seawater corrosion resistance.
The waterproofing rope of above-mentioned inserts 7 for forming for be added with water-proofing powder in cotton rope, water-proofing powder water-swellable, makes waterproofing rope meet water chap.
Above-mentioned wire armoring 9 is for strengthening the underwater drawing-resistant function of submarine cable, and tensile strength is high.
The scope of application of the present utility model: be mainly used in seabed or the bottom, provide unimpeded being connected between island and island, between island and land, between island and offshore platform, between offshore platform and platform, between offshore wind turbine and blower fan, between offshore wind turbine and continent or island, between two sides, rivers lake etc., basic mechanical design feature is referring to table 1.
Table 1: important technological parameters table of the present utility model:
Note 1: the check coefficient of submarine cable design power is 1.1-1.2.
Note 2: ampacity design condition: 1, sea bed temperature is 25 ℃, thermal resistance 0.7; 2, the beach soil moisture is 25 ℃, thermal resistance 1.0; 3, soil, land temperature is 40 ℃, thermal resistance 1.2.
Above-described embodiment is only preferred embodiment of the present utility model, not limits according to this protection range of the present utility model, therefore: all equivalences of doing according to structure of the present utility model, shape, principle change, within all should being covered by protection range of the present utility model.
