Description
Technical Field
The invention relates to the technical field of cable production, in particular to a waterproof ultraviolet light crosslinking insulated cable.
Background
The crosslinked cable is a short term for crosslinked polyethylene insulated cable, and refers to a cable with an insulating or protective layer made of crosslinked material. The cross-linked cable is usually suitable for power transmission and distribution lines with power frequency alternating current voltage of 500KV and below, and most of the existing high-voltage cables adopt cross-linked polyethylene insulated cables.
The existing crosslinked cable basically has the performances of insulation, ultraviolet light resistance and the like, but the waterproof performance is not very strong, and water can permeate into the cable due to continuous rain in the south every rainy season, so that the performance of the cable is influenced, even the cable cannot be used, and the economic cost is increased.
Disclosure of Invention
In order to solve the technical problem, the invention provides a waterproof ultraviolet crosslinking insulated cable.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
the utility model provides a waterproof type ultraviolet ray crosslinked insulated cable, includes the cable core group, by interior and outer cladding in proper order at the outside insulating layer of cable core group, shielding layer, inner protective layer, the outer protective layer that form by the transposition of a plurality of cable cores, be equipped with the waterproof layer between shielding layer and the inner protective layer, circumference equipartition has a plurality of water-swelling area in the waterproof layer, and a plurality of water-swelling area contacts each other and leaves the space between water-swelling area and the waterproof layer.
Further, an isolation layer is arranged between the insulation layer and the shielding layer, and the isolation layer is composed of a particulate water absorbent.
Furthermore, each water-absorbing expansion belt is of a flat elliptic structure.
Further, the water-swelling band is composed of a super absorbent resin polymer and a water-permeable outer wrapping cloth.
The invention has the beneficial effects that:
compared with the prior art, the waterproof layer, the water-swelling band and the isolation layer are arranged, so that the waterproof cable is provided with the double-layer waterproof layer, the first layer can prevent a large amount of rainwater from permeating through water-swelling filling, and the second layer of waterproof layer can effectively prevent water vapor from permeating, so that the cable core is not influenced in plum rain seasons, the normal use of the cable is ensured, the damage rate of the cable is reduced, and the increase of economic cost is effectively restrained.
Drawings
The invention is further illustrated with reference to the following figures and examples:
FIG. 1 is a schematic structural diagram of the present invention.
In the figure: 1. a cable core; 2. an insulating layer; 3. an isolation layer; 4. a shielding layer; 5. a waterproof layer; 6. a water-swellable tape; 7. an inner protective layer; 8. and an outer protective layer.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the invention is further explained in the following with the accompanying drawings and the embodiments.
As shown in fig. 1, a waterproof type ultraviolet crosslinking insulated cable, include the cable core group that forms by the transposition of a plurality of cable cores 1, from interior to exterior in proper order the cladding at cable core group outside insulating layer 2, shielding layer 4, inner protective layer 7, outer protective layer 8, be equipped with waterproof layer 5 between shielding layer 4 and the inner protective layer 7, the circumference equipartition has a plurality of water-swelling area 6 in waterproof layer 5, and a plurality of water-swelling area 6 contacts each other and leaves the space between water-swelling area 6 and the waterproof layer 5.
As a further improvement of the invention, a separation layer 3 is arranged between the insulating layer 2 and the shielding layer 4, and the separation layer 3 is composed of a particulate water absorbent.
As a further improvement of the invention, each water-absorbing expansion belt 6 is of a flat elliptic structure.
As a further improvement of the invention, the water-swelling band 6 is composed of a super absorbent resin polymer and a water-permeable outer wrap.
As a further improvement of the invention, the cable core group consists of a cable core positioned in the middle and six cable cores distributed in the circumference of the middle cable core, the insulating layer 2 and the shielding layer 4 can effectively insulate and shield the cable core group inside, wherein the insulating layer 2 is formed by extruding and coating ultraviolet irradiation crosslinked polyethylene, and the insulating property meets the use requirement; the shielding layer 4 is formed by weaving a plurality of copper wires, so that the electromagnetic wave interference is inhibited, and the cable core is protected.
The water swelling area 6 is equipped with five, and five water swelling area 6 are mutually contacted each other, divide waterproof layer 5 into inside and outside two-layer, when 5 outer courses of waterproof layer had water infiltration, must just can infiltrate in the shielding layer 4 through water swelling area 6 earlier. Because the water-absorbing expansion belt 6 is composed of super absorbent resin polymer and water-permeable outer wrapping cloth and is of a flat elliptic structure, the water-absorbing expansion belt 6 can absorb a large amount of water to expand, and then the waterproof layer 5 is completely filled, so that the waterproof performance is further enhanced.
Furthermore, the addition of the barrier layer 3 consisting of a particulate water-absorbing agent for a second layer of waterproofing ensures that the penetration of water into the insulating layer 2 is effectively prevented even if water penetrates through the barrier layer 4 via the waterproofing layer 5.
Compared with the prior art, the waterproof layer, the water-swelling band and the isolation layer are arranged, so that the waterproof cable is provided with the double-layer waterproof layer, the first layer can prevent a large amount of rainwater from permeating through water-swelling filling, and the second layer of waterproof layer can effectively prevent water vapor from permeating, so that the cable core is not influenced in plum rain seasons, the normal use of the cable is ensured, the damage rate of the cable is reduced, and the increase of economic cost is effectively restrained.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
