Description
Technical field
The utility model relates to field of cable technology, more particularly to a kind of highly reliable insulation corrosion proof cable.
Background technique
Currently, some weather conditions more humid region, common cable can not withstand the influence of harsh weather, make
It is short with the service life, to produce huge loss to the productivity effect of enterprise.
Be installed on the power cable of outdoor direct-burried (or being laid in the heavier area of moisture in air) due to long-time by
The erosion of underground or moisture in air, the chemical component for easily causing cable jacket is degraded, so as to cause cable jacket
Surface generates the phenomenon that cracking, and the cracking of cable jacket will lead to the intrusion cable inner such as steam and foreign matter, to influence cable
Normal work, the degree of aging of cable itself is further aggravated, influences the service life of cable.
So how to develop a kind of corrosion resistant cable of water-blocking moistureproof is that those skilled in the art are in the urgent need to address
Problem.
Utility model content
The technical problem to be solved by the utility model is in order to overcome the shortcomings in the prior art, the utility model mentions
For a kind of highly reliable insulation corrosion proof cable.
The utility model solves its technical problem technical solution to be taken: a kind of highly reliable insulation anti-corrosion electric
Cable, including cable core, the cable core are twisted by more cores, and the core includes the conductor set gradually from inside to outside, interior
Semiconductive shielding layer, insulating layer, out semiconductor layer and metal screen layer are filled with filled layer between the core, described
It is surrounded with the first two-sided waterstop on cable core, is surrounded with the second two-sided waterstop outside the first two-sided waterstop, described first
Two-sided waterstop and the second two-sided waterstop joint are equipped with splicing tape, and middle position is bonded with PH examination on the inside of the adhesive tape
Paper, separation sleeve is extruded on the second two-sided waterstop, and the separation sleeve is equipped with protective metal shell, sets on the protective metal shell
There is erosion resistant coating, oversheath is arranged with outside the protective metal shell.
On the one hand metal screen layer is used to shield external electrical field signal, on the other hand as the channel of Leakage Current, in electricity
It when cable is struck by lightning, can be drained, play a part of to protect cable.
Protective metal shell is set on separation sleeve by the way of chain armouring, when the protective metal shell carries out chain armouring, is adopted
With anti-corrosion lotion to be applied to the surface of protective metal shell, so that erosion resistant coating is formed, due to using coating anti-corrosion lotion
Chain Sheathed metal sheath, and the material of protective metal shell is typically chosen aluminum alloy strip, since aluminium alloy is oxidized in air,
Its surface will form one layer of fine and close sull, can prevent the further oxidation of the metallic sheath, while in anti-corrosion lotion
Under the action of, the gap between layers of chain Sheathed metal band is filled with anti-corrosion lotion, this again by the cable core of cable with
The external world is isolated, and moisture or moisture is further prevented to be immersed in inside cable core.
Insulating layer use highdensity peroxide crosslinked polyethylene, dielectric loss angle tangent 0.008, therefore
In the case where cable operates normally for a long time, the ageing-resistant performance of insulating layer is preferable.And extruded outside protective metal shell one layer it is low
Density polyethylene oversheath, since jacket material polyethylene has good resistance effect, the construction of cable is certain
Multiple stop water is used in degree, to extend the service life of cable.
Due to using protective metal shell, has the function of preferably shielding outer signals, the interference of outer signals can be stopped.
Two-sided waterstop prevents moisture or moisture to be immersed in inside cable core, splicing tape is used for two sections for protecting core
The connection between connection and two section of second two-sided waterstop between first two-sided waterstop, PH test paper are examined for staff
When repairing, check whether PH test paper changes colour, to learn whether the first two-sided waterstop and the second two-sided waterstop joint intake.
Further, the splicing tape is identical as the described first two-sided waterstop and the second two-sided band structure that blocks water, described viscous
Color indicating regions are equipped on the outside of tape splicing.Splicing tape is identical as the first two-sided waterstop and the second two-sided band structure that blocks water, and is used for
Guarantee the block-water performance of joint, color indicating regions is set on the outside of adhesive tape, for facilitating staff to be quickly found out connector
Splicing tape.
The beneficial effects of the utility model are: a kind of highly reliable insulation corrosion proof cable provided by the utility model, uses
Around two-sided waterstop of double-baging, chain Sheathed metal sheath and oversheath using polyethylene etc., with common water repellent electric cable
Compare, block water, moisture-proof function it is more preferable, the service life is longer for cable, more can be suitably used for harsh climate environmental condition.
