Description
Technical field
The present invention relates to technical field of cable, especially a kind of novel energy-conserving water repellent electric cable.
Background technology
Along with to insulation water suction and the research of water tree and the intensification of understanding, there is a growing awareness that water resistance centering height
The importance of piezoelectric forces cable.Cable is all proposed waterproof by the most increasing user and various areas occasion
Requirement.The water repellent electric cable of the most various structures arises at the historic moment.
The electrician being currently used for electric power transmission mostly uses copper material with conductive material, but due to internal copper resource scarcity, has
The copper material of about 70% needs import, and climbing up and up along with World Copper valency so that the cost of investment of conductive material is more come
The highest, the most excessive to the resource consumption of copper material.China is a country for the rich lean copper of aluminum, domestic have substantial amounts of bauxite resource but
Less than making full use of, it it is waste greatly.Country advocates and builds a conservation-minded society now, is also encouraging employing with " aluminum in industry
Joint copper ".
Owing to electrician is low by the conductivity of hard state pure aluminum wire material, yield strength is low, and deformation of creep amount is big, and percentage elongation is relative
Less, when electric power transmits, because there is the bigger deformation of creep after long-term operation or current overload, thus joint can be caused
Loosen, contact resistance increases, and produces safety problem.Therefore, pure aluminum wire is abandoned the most in a lot of application scenarios.
Solve the defect problem of fine aluminium at present at electrician's conductive material field Aluminium Alloys in Common Use material, to realize, " aluminum closes
Jin Dynasty copper " purpose, thus saving copper material consumption.
Traditional copper aluminum water-blocking conductor typically uses and presses circular configuration, and conductor is indulged bag semiconductive between layers and blocked water
Band.If but use above-mentioned technique to produce aluminium alloy water-blocking conductor, can not realize, because traditional aluminium alloy conductor is raw
Production. art is first stranded after annealing, if using which to produce, then indulges the semiconductor waterstop of bag when producing conductor in annealing
After can lose block-water effect.Therefore a kind of new technology must be used to block water aluminium alloy conductor producing molded line.
The most traditional water repellent electric cable normally only uses and blocks water filling and the band that blocks water reaches the purpose that blocks water, but this
If water repellent electric cable is immersed in water for a long time, not having good block-water effect, cable insulation can enter moisture at short notice
And there is puncture short.
Summary of the invention
The applicant is for the shortcoming in above-mentioned existing production technology, it is provided that a kind of novel energy-conserving water repellent electric cable, so that
It has that good energy-conserving effect, block-water performance be excellent, length in service life and the feature of environmental protection.
The technical solution adopted in the present invention is as follows:
A kind of novel energy-conserving water repellent electric cable, including the cable core being twisted into by many insulated wire cores, described insulated wire cores is by hindering
Water conductor forms in the water resistant tree insulating barrier outside water-blocking conductor with extruding, the most wrapped band that blocks water, gold outside described cable core
Belong to sheath water blocking layer and complex group water restrictive coating, in the band that blocks water, be filled with the filling yarn that blocks water.
Its further technical scheme is:
Described conductor is the aluminium alloy conductor that blocks water of molded line lay configuration；
Described insulating barrier uses water resistant tree cross-linked polyethylene insulating material or modified water resistant tree second the third Insulation Material；
Described protective metal shell water blocking layer is extruded by aluminum or aluminum alloy bar and forms；
The described compound restrictive coating that blocks water is by indulging alclad plastic composite strip and modification high-density polyethylene forms.
Beneficial effects of the present invention is as follows:
(1) group water conductor uses aluminum alloy materials, can preferably replace copper conductor cable, and it is easy to solve electrician's fine aluminium conductor
The problems such as oxidation, creep-resistant property difference, and material cost is relatively low, economic performance is excellent；
(2) group water conductor uses molded line twisting process to add semiconductor waterstop and indulges pack arrangement, and conductor compacting coefficient is high, blocks water
Effective, and conductor diameter 5% can be reduced, save each operation raw material usage amount more than 10%；
(3) insulating barrier uses water resistant tree cross-linked polyethylene insulating material or modified water resistant tree second the third Insulation Material, can effectively keep away
Exempting from insulation caused because of affecting by water tree puncture；
(4) restrictive coating uses vertical alclad plastic composite strip to add modification high-density polyethylene structure, can improve the radial direction resistance of cable
Outlet capacity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein: 1, water-blocking conductor；2, water resistant tree insulating barrier；3, block water filling yarn；4, block water band；5, protective metal shell blocks water
Layer；6, the compound restrictive coating that blocks water.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the detailed description of the invention of the present invention is described.
As it is shown in figure 1, the present embodiment includes the cable core being twisted into by many insulated wire cores, described insulated wire cores is led by blocking water
Body 1 forms in the water resistant tree insulating barrier 2 outside water-blocking conductor 1 with extruding, and water-blocking conductor 1 is that the aluminum that blocks water of molded line lay configuration closes
Gold conductor, can preferably replace copper conductor cable, and solve the problems such as electrician's fine aluminium conductor is oxidizable, creep-resistant property is poor, and
And material cost is relatively low, economic performance is excellent, water-blocking conductor 1 also uses molded line twisting process to add the vertical bag of semiconductor waterstop simultaneously
Structure, conductor compacting coefficient is high, and block-water effect is good, and can reduce conductor diameter 5%, saves each operation raw material usage amount
More than 10%；Insulating barrier 2 uses water resistant tree cross-linked polyethylene insulating material or modified water resistant tree second the third Insulation Material, can effectively avoid
What insulation was caused because of affecting by water tree punctures；The most wrapped band 4 that blocks water, protective metal shell water blocking layer outside described cable core
5 and complex group water restrictive coating 6, being filled with the filling yarn 3 that blocks water in the band 4 that blocks water；Described protective metal shell water blocking layer 5 is aluminum or aluminum conjunction
Gold, the compound restrictive coating 6 that blocks water is made up of vertical alclad plastic composite strip and modification high-density polyethylene, can improve the radial water-resisting of cable
Ability.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees right
Requirement, within protection scope of the present invention, can make any type of amendment.
