Abstract
The utility model discloses a novel water blocking cable which is composed of a number of cable cores, a water blocking rope, an outer water blocking tape and an outer sheath, wherein each cable core is composed of conductors, an inner water blocking tape and an insulation layer. The novel water blocking cable is characterized in that the surfaces of the conductors are wrapped with the inner water blocking tape; the outer side of the inner water blocking tape is wrapped with the insulation layer; the number of the conductors is four, and the conductors are fan-shaped; the water blocking rope wraps the four fan-shaped conductors together to form a circular structure; the outside of the water blocking rope is wrapped with the outer water blocking tape; and the outer side of the outer water blocking tape is wrapped with the outer sheath. According to the utility model, the structure of each conductor is designed in the shape of a fan, thus the water blocking performance of the cable is further improved, and the production cost is reduced; the outer water blocking tape is arranged on the inner side of the outer sheath, which prevents water from seeping into the inner structure of the cable due to the damage of the outer protective layer structure of the cable; and a nylon sheath is used as the outer sheath of the cable, thus the excellent performance of wear resistance reduces cable poling, and the performance of water blocking of the cable is greatly improved.
Description
Technical field
The utility model relates to the cable technology field, particularly a kind of Novel waterproof cable.
Background technology
Along with the develop rapidly of China Power industry, cable has been used for many cities of each large main cities, especially eastern region of the whole nation more and more.Cable often adopts the modes such as direct-burried, cable trough, tunnel to lay in power engineering is used, and contacts with water unavoidably, and some cables are understood short-term or long period of soaking in water, and moisture slowly is penetrated into cable inside, therefore, and very good of the block-water performance of cable needs.
At present, provide a kind of water repellent electric cable among the Chinese patent application 201120224290.X, included inner wire, insulating barrier and oversheath, be filled with the gasket for packing that blocks water between described insulating barrier and the oversheath.Also be provided with wrapped waterstop between insulating barrier and the oversheath.This utility model has increased block water gasket for packing and waterstop between insulating barrier and oversheath, when water is entered because their suction and expansion character, thereby greatly reduce the maintenance cost of cable; Jacket material is polyethylene sheath material, and its mechanical strength is all strong than PVC, and waterproof, and cable is got better protection; Simple in structure, result of use good, low cost of manufacture.
But, since the water repellent electric cable inner wire that provides of this utility model be shaped as circle, in the very large space of the stranded rear appearance of cable core, in the space, filled the gasket for packing that blocks water after, still have certain space, there is certain impact in the existence in space to the block-water performance of cable.
Summary of the invention
The purpose of this utility model provides a kind of Novel waterproof cable, solves existing water repellent electric cable and all exists the external sheath layer structure generation damage of space, cable to cause the internal structure seepage problem from conductor to heterogeneous cable core.
For solving the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of Novel waterproof cable, comprise a plurality of cable cores, waterproofing rope, outer waterstop and oversheath, it is characterized in that: described cable core is comprised of conductor, interior waterstop, insulating barrier, conductor is sector structure, and conductor has 4, and conductive surface is coated with interior waterstop, the interior waterstop outside is coated with insulating barrier, waterproofing rope is coated togather 4 fan-shaped cable cores and consists of a circular configuration, and waterproofing rope is coated with outer waterstop, and the outer waterstop outside is coated with oversheath.
Described conductor structure be designed to 90 ° fan-shaped, this structure makes the cable core group stranded very tight, does not have unnecessary space to produce.
Described oversheath is nylon sheath wire, and nylon has very high mechanical endurance energy, also has good electrical insulation properties simultaneously, and excellent resistance to wear can reduce cable pipe.
The beneficial effects of the utility model are: fan-shaped by conductor structure is designed to, make conductor stranded very tight, there is not unnecessary space to produce, the area of cable core contact outside is reduced, make conductor reduced by the area of extraneous damage, further improve the water resistance of cable, and the cable size behind the stranding is reduced, save and produce material, reduce production costs.In addition, be provided with outer waterstop by the inboard at oversheath, that can avoid cable infiltrates the cable internal structure because outside shielding layer structure causes water after damaging, use nylon sheath wire as the oversheath of cable, excellent anti-wear performance can reduce cable pipe, improves greatly the block-water performance of cable.
Description of drawings
Fig. 1 is the cross sectional representation of Novel waterproof cable described in the utility model.
Among the figure: waterstop, 3-insulating barrier, 4-waterproofing rope, the outer waterstop of 5-, 6-oversheath in 1-conductor, the 2-.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, a kind of Novel waterproof cable, comprise a plurality of cable cores, waterproofing rope 4, outer waterstop 5 and oversheath 6, wherein each cable core is comprised of conductor 1, interior waterstop 2, insulating barrier 3, and conductor 1 surface is coated with interior waterstop 2, interior waterstop 2 outsides are coated with insulating barrier 3, conductor 1 has 4, is shaped as fan-shapedly, and waterproofing rope 4 is coated togather 4 sector conductors 1 and consists of a circular configuration, waterproofing rope 4 is coated with outer waterstop 5, and outer waterstop 5 outsides are coated with oversheath 6.
Execution mode of the present utility model is as follows:
With the shape of cable conductor 1 be designed to 90 ° fan-shaped, be provided with interior waterstop 2 on the surface of conductor 1, at interior waterstop 2 outer cladding insulating barriers 3, then use waterproofing rope 4 that 4 sector conductors 1 are coated togather, consist of a circular configuration, make that closely there is not the space in contact between the cable core of pair twist, reduce the diameter of whole cable, and improve water resistance; Arranged outside in waterproofing rope 4 has outer waterstop 5, and outer waterstop 5 is coated with oversheath 6, and the nylon sheath wire that oversheath 6 is made for nylon material, nylon sheath wire have excellent anti-wear performance, can reduce cable pipe, improve greatly the block-water performance of cable.
