Abstract
The utility model relates to a rated voltage 10kV high strength waterproofing type overhead insulated cable, the outer transposition of steel core is sticis the aluminium conductor and is formed the aluminium conductors (cable) steel -reinforced layer, and between each layer aluminium conductor of aluminium conductors (cable) steel -reinforced in situ, fill the yarn that blocks water between aluminium conductor and the steel core, around the package area that blocks water, the crosslinked polyethylene insulating layer is set to the crowded package semiconductive shielding layer of the outband that blocks water, semiconductive shielding layer crowded package black weatherability water -resistant outward outside the aluminium conductors (cable) steel -reinforced layer. This is novel on the basis of characteristics such as original " high voltage, large capacities, easily lay ", has improved high strength, the corrosion resisting property of overhead insulated cable's block -water performance, insulating water -resistant tree performance and conductor greatly to the security and the life of cable have been improved. In the abominable area of environment, the realization is crossed over greatly, big length is laid, also the corresponding installation cost who reduces the cable.
Description
Technical field
This utility model relates to electric wire field, is specifically related to a kind of rated voltage 10kV high intensity water blocking type overhead insulating cable.
Background technology
Along with rural area, cities and towns and outlying district expanding economy, the most to the demand of aerial insulated cable, more and more higher to its performance requirement.Weatherability to be had, high voltage output performance, high intensity to be possessed, high life, the performance such as waterproof.In the past the requirement blocked water was limited primarily in the application of submarine cable, extra-high-tension cable and communication cable.Along with to insulation water suction and the research of water tree and the intensification of understanding, there is a growing awareness that the water resistance importance to medium and high voltage cable.At the most rainy, snowy district, increasing user proposes waterproof requirement to cable.Without block-water performance, cable once sustains damage, and water invades inside cable from injury region, and then penetrates into the gap (between conductor strand, extruding outer semiconducting layer, screen layer etc.) within cable.Along cable Longitudinal Extension, thus long length cable is caused to use.And aerial insulated cable is all Great span, long length lays.Therefore water is internal once immerse cable, and its creepage distance should be the shortest more good.
Utility model content
For the infiltration after stoping cable to soak, improve safety and the service life of aerial insulated cable, this novel offer one rated voltage 10kV high intensity water blocking type overhead insulating cable, it is applicable to the most rainy, ice and snow storm wind area, conductor gap is used to fill water blocking yarn, the method of the outer wrapped waterstop of conductor, stops the immersion of water.Use weather resistant water resistant tree crosslinked polyetylene insulated, improve the electrical property of cable, ageing properties and service life.
For realizing object above, by the following technical solutions: rated voltage 10kV high intensity water blocking type overhead insulating cable, the outer stranded aluminium conductor that presses of steel core forms steel-cored aluminium strand layer, in steel-cored aluminium strand layer between each layer aluminium conductor, between aluminium conductor and steel core, fill water blocking yarn, the outer wrapped waterstop of steel-cored aluminium strand layer, extrude semiconductive shielding layer outside waterstop, outside semiconductive shielding layer, extrude the black weatherability crosslinked polyetylene insulated layer of water resistant tree.
Described steel core is zinc-plated steel core, and aluminum conductor layer is stranded round compacted comductor.
Described steel-cored aluminium strand is to press aluminum stranded conductor outside high intensity, corrosion-resistant zinc-plated steel core, and relatively aluminium conductor is compared, and tensile strength is high, can realize Great span, long length lays requirement；Relatively copper conductor is compared, and when possessing identical conduction performance, cable weight is lighter more than one times than copper conductor cable, and the beneficially high-altitude of cable sets up, and correspondingly reduces construction cost.
Described black weatherability water resistant tree is crosslinked polyetylene insulated, has more excellent electrical property, mechanical performance, has more resisting environmental stress and cracking, water resistant tree, the special energy such as increase the service life.
This utility model beneficial effect: on the basis of characteristics such as original " high voltage, Large Copacity, easily lay ", substantially increase the block-water performance of aerial insulated cable, insulation water tree resistant property and the high intensity of conductor, decay resistance, thus improve safety and the service life of cable.In ruthless area, it is achieved Great span, long length lay, also correspondingly reduce the installation cost of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
As shown in the figure: 1, steel core；2, aluminium conductor；3, water blocking yarn；4, waterstop；5, semiconductive shielding layer；6, the crosslinked polyetylene insulated layer of black weatherability water resistant tree.
Detailed description of the invention
Embodiment
Further illustrating below in conjunction with the accompanying drawings, Extra High Strength, the most stranded aluminium conductor (2) that presses of steel core (1) of thickening zinc layers form steel-cored aluminium strand；Gap filling water blocking yarn (3) between each layer aluminium conductor (2), between aluminium conductor (2) and steel core (1) layer when steel-cored aluminium strand presses, steel-cored aluminium strand press after wrapped waterstop (4)；Semiconductive shielding layer (5) is extruded outside waterstop (4)；The black crosslinked polyetylene insulated layer of weatherability water resistant tree (6) is extruded outside semiconductive shielding layer (5).
Claims (2)
1. rated voltage 10kV high intensity water blocking type overhead insulating cable, it is characterized in that, the most stranded aluminium conductor (2) that presses of steel core (1) forms steel-cored aluminium strand layer, in steel-cored aluminium strand layer between each layer aluminium conductor, between aluminium conductor and steel core, fill water blocking yarn (4), the outer wrapped waterstop (4) of steel-cored aluminium strand layer, extrude semiconductive shielding layer (5) outside waterstop (4), outside semiconductive shielding layer (5), extrude the black crosslinked polyetylene insulated layer of weatherability water resistant tree (6).
Rated voltage 10kV high intensity water blocking type overhead insulating cable the most according to claim 1, it is characterised in that described steel core is zinc-plated steel core, aluminum conductor layer is stranded round compacted comductor.
