Abstract
The invention provides a split type flame-retardant cable sheath which comprises two split semi-cylinders, wherein the two split semi-cylinders are fixed together through outer hexagon bolts and screw nuts so as to form cable sheaths; the seams between the two split semi-cylinders are sealed through self-limited sealing strips; the cable sheaths are of fixed lengths; different cable sheaths are fixed through studs, nylon locking screw nuts and bolt covers; lightening holes are formed in the surfaces of the cable sheaths; cable channels are uniformly distributed in the semi-cylinders; three cable holes are respectively formed in each cable channel. The split type flame-retardant cable sheath has the functions of partitioning, fixing and protecting cables, and the cables can be effectively prevented from damage caused by winding, corrosion, overheat and the like.
Description
Technical field
The present invention relates to a kind of cable protective kit, be specifically related to a kind of split type fire-retardant cable protective kit.
Background technology
Cable generally includes outer jointing jacket, avoids external contamination or external force impact in order to protect cable internal structure.Such as, typical coaxial cable comprises center conductor, outer conductor and the outer jointing jacket that insulated body surrounds.Some protective sleeves are made up of the material of relative stiffness, to protect the internal structure of cable.When cable is arranged on open air, no matter aerial or underground, the cable with rigid protective overcoat is very useful, because this sheath can provide extra protection.Wind electric power generation cable, due to residing environment, wind-force is comparatively large, and cable easily tangles, and easily breaking out of fire, these situations all may cause cable line destroyed and security incident occurs, and then affect the stable operation of whole electric power system.In addition, cable can discharge large energy time accidents such as (such as puncture) blasts having an accident, and can cause harm in various degree, even also can cause serious second accident to surrounding enviroment.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of split type fire-retardant cable protective kit, has high protection, shock resistance, good pressure-resistant performance, the fire-resistant advantage such as anticorrosion, and cable is flexibly bending after installing protective jacket additional, carries, easy for installation.
In order to solve the problem, the present invention by the following technical solutions: a kind of split type fire-retardant cable protective kit of design, it is by the injection molding Split type semicircular cylinder of nylon material, the cable protective kit be fixed up by outer-hexagonal screw bolt and nut.Cable protective kit has fixing length, is fixed between adjacent cable protective kit by stud, nylon locking nuts and bolt lid.By sealing from prohibiting formula sealing strip between two Split type semicircular cylinders.The surface of cable protective kit is provided with lightening hole, can alleviate the weight of cable protective kit with this, is conducive to cable simultaneously and dispels the heat.Cable passage is evenly distributed in semicylinder, is provided with 3 cable aperture in each cable passage.
Further, the length of cable protective kit is 250mm-300mm.
Further, the diameter of cable protective kit is 290mm-320mm.
Further, the diameter of cable aperture is 25mm-30mm.
The beneficial effect that the present invention realizes is:
1, the effect that segmentation is fixing, protect is played to cable, damages such as effectively preventing cable to be wound around, wear and tear, be overheated.
2, cable protective kit adopts the material with anti-flaming function, meets UL94-V0 flame retardant rating, and adopt segmentation structure, can adopt suitable compound mode according to blower fan environment, the overall length of cable protective kit is unrestricted, can obtain required random length.
3, structure of the present invention is simple, easy to operate, uses reliable, is convenient to promote the use of.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiments of the present invention are described further:
Fig. 1 is structural representation of the present invention.
Fig. 2 is vertical view of the present invention.
1-cable protective kit, 2-Split type semicircular cylinder, 3-bolted cover, 4-outer-hexagonal bolt, 5-nut, 6-stud, 7-nylon locking nut, 8-is from prohibiting formula sealing strip, 9-lightening hole, 10-cable aperture, 11-cable passage.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the invention will be further described.
As shown in Figure 1, split type fire-retardant cable protective kit of the present invention, it is by the injection molding Split type semicircular cylinder 2 of nylon material, the cable protective kit 1 be fixed up by outer-hexagonal bolt 4 and nut 5.Cable protective kit 1 has fixing length, is fixed between adjacent cable protective kit 1 by stud 6, nylon locking nut 7 and bolted cover 3.By sealing from prohibiting formula sealing strip 8 between two Split type semicircular cylinders 2.The surface of cable protective kit 1 is provided with lightening hole 9, can alleviate the weight of cable protective kit 1 with this, is conducive to cable simultaneously and dispels the heat.
As shown in Figure 2, be the vertical view of cable protective kit.Cable passage 11 is evenly distributed in semicylinder, is provided with 3 cable aperture 10 in each cable passage 11.
Further, the diameter of cable protective kit is 290mm-320mm.
Further, the diameter of cable aperture is 25mm-30mm.
Further; the length of cable protective kit is set to 250mm-300mm; to ensure that this cable protective kit has guard space long as far as possible; simultaneously also can not be long and cause being not easy to installing due to the length of cable protective kit; according to actual needs, preferably the length of cable protective kit can be arranged at 260mm.
Split type fire-retardant cable protective kit of the present invention, the overall length of cable protective kit is unrestricted, can obtain required random length, and without the need to operations such as wraparound, welding, polishing, polishings.
Owing to being arranged at the ruggedized construction (outer-hexagonal bolt, nut) at these cable protective kit two ends, cable protective can be made to be enclosed within more difficult cracking when being expanded, and the two ends of cable protective kit can more closely and fixing wrap cable, ensure that this cable protective kit has better sealing, and then effectively prevent because of cable bad cause security incident, and, the sealing good due to this cable protective kit and anti-flammability, when also effectively can prevent cable generation combustion phenomena, this burning is extinguish fast because of anoxic.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, any people being familiar with this technology is in the technical scope disclosed by the present invention; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
