Abstract
The utility model relates to the technical field of cables, and a lay ageing resistance cable at bottom of ground is disclosed, including the cable core, the external fixed surface of cable core has cup jointed insulating cover, the external fixed surface of insulating cover has cup jointed waterproof endotheca, the external fixed surface of waterproof endotheca has cup jointed waterproof overcoat, the external fixed surface of waterproof overcoat has cup jointed anti-aging overcoat. This lay in ageing resistance cable at bottom of a ground, through setting up anti-aging overcoat and rubber protective wax, because anti-aging overcoat has heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance to the effectual surface of having avoided the cable phenomenon of ageing appears, simultaneously because rubber protective wax possesses anti-ozone, sunlight and ageing effect, not only by a wide margin improvement the ageing resistance of this cable, simultaneously also great increase the life of waterproof arc piece, consequently, the practicality of this cable has been improved.
Description
Technical Field
The utility model relates to the technical field of cables, specifically be an ageing resistance cable of laying in the ground bottom.
Background
Cables are generally rope-like cables made up of several twisted conductors, each conductor being insulated from the other and usually twisted around a center, covered with a highly insulating covering, and usually erected in the air or installed underground and underwater, and are commonly used for telecommunication or power transmission.
At present, current cable often needs to bury it deeply in underground in order to satisfy the installation demand, however because the cable is at the in-process of long-term the use, the ageing phenomenon takes place for the protective sheath of its surface easily to lead to the surface of cable to appear the crack, moisture in the soil underground at this moment passes through the crack easily and gets into the inside of cable, thereby leads to the cable to take place the short circuit easily, has influenced the normal use of cable, consequently needs to improve it.
SUMMERY OF THE UTILITY MODEL
The utility model is not enough to prior art, the utility model provides a lay ageing resistance cable at bottom of the earth, possess the advantage that anti-aging and waterproof performance are good, solved current cable in order to satisfy the installation demand, often need bury it in the underground deeply, however because the cable is at the in-process of long-term use, the ageing phenomenon takes place easily for the protective sheath of its surface, thereby lead to the surface of cable to appear the crack, moist moisture passes through the inside that the crack entered into to the cable easily in the underground soil this moment, thereby lead to the cable to take place the short circuit easily, the problem of cable normal use has been influenced.
The utility model provides a following technical scheme: the utility model provides a lay ageing resistance cable at bottom of ground, includes the cable core, the fixed surface of cable core has cup jointed insulating cover, the fixed surface of insulating cover has cup jointed waterproof endotheca, the fixed surface of waterproof endotheca has cup jointed waterproof overcoat, the fixed surface of waterproof overcoat has cup jointed anti-aging overcoat, the surface of waterproof overcoat has been paintd and is located the inside PVC oleamen coating of anti-aging overcoat, the arc notch has been seted up to the surface of anti-aging overcoat, the fixed cover in inside of arc notch has been met waterproof arc piece, rubber protective wax has been paintd to the surface of waterproof arc piece.
Preferably, the number of the arc-shaped notches is several, the distances between the arc-shaped notches are equal, and the sizes of the arc-shaped notches are the same.
Preferably, the arc-shaped waterproof sheet is made of butyl rubber, and the arc-shaped waterproof sheet is in an arc shape.
Preferably, the anti-aging jacket is made of fluororubber, and the outer surface of the anti-aging jacket presents a tooth shape.
Compared with the prior art, the utility model discloses possess following beneficial effect:
1. this lay in ageing resistance cable at bottom of a ground, through setting up anti-aging overcoat and rubber protective wax, because anti-aging overcoat has heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance to the effectual surface of having avoided the cable phenomenon of ageing appears, simultaneously because rubber protective wax possesses anti-ozone, sunlight and ageing effect, not only by a wide margin improvement the ageing resistance of this cable, simultaneously also great increase the life of waterproof arc piece, consequently, the practicality of this cable has been improved.
2. This ageing resistance cable of laying in the ground end, through setting up waterproof endotheca, waterproof overcoat, waterproof arc piece, and PVC oleamen coating, because the effect of waterproof arc piece, will follow the infiltration of moisture in the outside prevention soil of cable, simultaneously because waterproof endotheca, waterproof overcoat and PVC oleamen coating all have waterproof performance, thereby the inside waterproof nature of cable has been improved, moisture infiltration to the inside of cable has been avoided, and then the problem of influence cable core normal operating, the effectual phenomenon that prevents the cable and take place the short circuit, consequently, further improvement the practicality of this cable.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a cable core; 2. an insulating sleeve; 3. a waterproof inner sleeve; 4. a waterproof jacket; 5. an anti-aging coat; 6. waterproof arc sheets; 7. rubber protective wax; 8. PVC factice coating; 9. an arc-shaped notch.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, an anti-aging cable laid on the ground comprises a cable core 1, an insulation sleeve 2 is fixedly sleeved on the outer surface of the cable core 1, a waterproof inner sleeve 3 is fixedly sleeved on the outer surface of the insulation sleeve 2, a waterproof outer sleeve 4 is fixedly sleeved on the outer surface of the waterproof inner sleeve 3, an anti-aging outer sleeve 5 is fixedly sleeved on the outer surface of the waterproof outer sleeve 4, the anti-aging outer sleeve 5 is made of fluororubber, the outer surface of the anti-aging outer sleeve 5 is tooth-shaped, the fluororubber has heat resistance, oxidation resistance, oil resistance, corrosion resistance and atmospheric aging resistance, so that the anti-aging capacity of the cable is improved, a PVC factice coating 8 located inside the anti-aging outer sleeve 5 is smeared on the outer surface of the waterproof outer sleeve 4, the PVC factice coating 8 is made of polyvinyl chloride, coal tar and a proper amount of modified materials, and the like, and the PVC fact, Elastoplasticity, better cold resistance, corrosion-resistant and ageing resistance, also further improvement the ageing resistance of this cable, arc notch 9 has been seted up to the surface of anti-aging overcoat 5, the quantity of arc notch 9 is a plurality of, distance between a plurality of arc notch 9 each other equals, a plurality of arc notch 9's size is the same, arc notch 9's inside fixed cover has been cup jointed waterproof arc piece 6, waterproof arc piece 6 is made by butyl rubber, and waterproof arc piece 6's appearance presents for the arc piece, butyl rubber has heat-resisting, ozone-resistant, ageing-resistant, chemical and waterproof performance, rubber protective wax 7 has been scribbled to waterproof arc piece 6's surface, rubber protective wax 7 has ozone-resistant, effects such as sunlight and ageing, can obviously prolong rubber products's life simultaneously.
