Abstract
The utility model discloses a transmission cable used for a coastal power generation field. The cable comprises three groups of cores. The cores are formed by conductors, conductor shielding layers, insulating layers, insulation shielding layers, copper tape armor layers, semi-conductive water blocking layers and water-blocking wrapping tapes, wherein the conductor shielding layers, the insulating layers, the insulation shielding layers, the copper tape armor layers, the semi-conductive water blocking layers and the water-blocking wrapping tapes successively wrap the conductors. A water-blocking filler is filled in a gap among the three groups of cores. An aluminum-plastic longitudinal cladding, a water-blocking inner jacket and a steel-tape armor layer are arranged outside a cabling core. A corrosion-resistant sheath is arranged on a periphery of the cable. Compared to the prior art, by using the cable of the utility model, during cabling, a high-expansibility water-absorption filling material is used to carry out filling; a high-expansibility water-absorption double-side water-blocking tape with a thickness of 0.3mm is used to carry out overlapping and wrapping; simultaneously an aluminum-plastic composite tape and an extruded polyolefin inside liner longitudinally wrap the cabling core; an aluminum-plastic metal sheath is taken as an inner sheath; good water blocking performance is possessed and good sea water and salt-spray corrosion tolerance performance is possessed too. The cable is suitable for high voltage transmission of the coastal power generation field.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of coastal generating field transmission cable.
Background technology
Along with the constant tension of energy supply, each state is, regenerative resource green at active development all, and wind energy be free from environmental pollution, do not destroy ecology, inexhaustible, nexhaustible a kind of energy, thereby favored.Most of coastal generating field all by the sea, weather conditions are moist, often be subjected to the invasion and attack of salt fog and seawater, cable will pass through many ponds when laying, the partial cables long period of soaking is in water, therefore require cable must have good block-water performance, must have good sea water resistance and salt air corrosion performance simultaneously.Existing common cable can't meet its demand.
The utility model content
The purpose of this utility model is to provide a kind of coastal generating field transmission cable of new construction, not only has good block-water performance, and has good tolerance seawater and salt air corrosion performance, to be suitable for the use of coastal generating field high voltage power transmission.
For realizing this purpose, the technical solution of the utility model is: a kind of coastal generating field transmission cable, comprise three groups of cores, described core reaches by conductor the conductor shield, insulating barrier, insulation screen, copper strips armour, semiconductive water blocking layer, the band that blocks water that coat thereon successively and forms, be filled with the filler that blocks water in space outside described three groups of cores, become that the cable core peripheral hardware has that plastic-aluminum is indulged covering, the inner cushion layer that blocks water, steel-tape armouring layer, described corrosion-resistant sheath is located at the cable outermost.
As preferably, annealing copper wire or tinned copper wire braiding that described copper strips armour is 0.2～0.4mm by diameter form.
As preferably, described conductor is zinc-plated stranded soft copper conductor.
As preferably, described corrosion-resistant sheath is comprised of wrinkle composite steel-plastic belt moisture-proof layer and the black polyethylene sheath of vertical bag overlap joint.
With respect to prior art, the utility model is when stranding, adopt high-expansion suction packing material to fill, and adopt the thick two-sided waterstop of height expansion suction of 0.3 mm to carry out overlapping wrapped, when having a small amount of moisture to enter, can be expanded to rapidly the height of 12 mm, thereby reach good block-water effect; Vertical alclad plastic composite strip outside the stranding cable core+extrude polyolefin lining layer, carry out embossing and bonding with bonded adhesives during the vertical bag of aluminum plastic belt, the plastic-aluminum metal sheath is as sheath, can effectively prevent the radially immersion of moisture, moisture, so not only have good block-water performance, and have good tolerance seawater and salt air corrosion performance, be more suitable for the use of coastal generating field high voltage power transmission.
Description of drawings
Fig. 1 is cross-sectional view of the present utility model.
Wherein: 1. conductor, 2. conductor shield, 3. insulating barrier, 4. insulation screen, 5. semiconductive waterstop, 6. copper strip shielding layer, the packing material that 7. blocks water, the band that 7. blocks water, the 8. vertical covering of plastic-aluminum, 9. inner cushion layer, 10. steel-tape armouring layer, 11. corrosion-resistant sheaths.
Embodiment
In conjunction with the embodiments the utility model is further illustrated with reference to the accompanying drawings.
As shown in Figure 1, a kind of coastal generating field transmission cable, comprise three groups of cores, described core reaches by conductor the conductor shield, insulating barrier, insulation screen, copper strips armour, semiconductive water blocking layer, the band that blocks water that coat thereon successively and forms, be filled with the filler that blocks water in space outside described three groups of cores, become that the cable core peripheral hardware has that plastic-aluminum is indulged covering, the inner cushion layer that blocks water, steel-tape armouring layer, described corrosion-resistant sheath is located at the cable outermost.Wherein, described copper strips armour is that the annealing copper wire of 0.2～0.4mm or tinned copper wire braiding form by diameter.Described conductor is zinc-plated stranded soft copper conductor.Described corrosion-resistant sheath is comprised of wrinkle composite steel-plastic belt moisture-proof layer and the black polyethylene sheath of vertical bag overlap joint.
The improvement that the utility model carries out with the transmission cable structure mainly for coastal generating field, the foregoing is only the utility model preferred embodiment, non-so namely limit to the scope of the claims of the present utility model, therefore simple and easy variation and the equivalent transformation of such as with the utility model specification and graphic content, doing, all should be contained in the scope of the claims of the present utility model.
