Description
Technical field
Material currently used for protective cable is generally casing, this kind of casing is generally socketed in the early period of installation cable in advance
In the periphery of cable, casing cannot be replaced after then cable connection is installed；In order to avoid frequent more casing replacing,
It is general to use the irony casing lasted a long time, but the method for this kind of protective cable also has its drawback：This kind of mode cost is higher,
And the cable of protection must just remove whole device once being damaged, and it is extremely inconvenient to safeguard, needs more labour.
Also have and protected by the casing of plastic construction, but this kind of casing is lacked in addition to of high cost, maintenance are inconvenient
Outside falling into, the performance requirements such as the ageing-resistant of this province of plastics, intensity are higher, and the service life is not grown, and it is larger to replace workload.
Although cable is when mounted, special cable, such as steel-tape armouring, this kind of electricity are used in weak exposed position
The processing of cable and hiding common cable jointing is relatively complicated, and joint connection is generally the most weak place of cable,
It is easy to cause the generation of safety accident, cannot ensure normally to use well.If the whole cable cost for using steel-tape armouring
Higher, the structure of buried casing originally can be used in hiding part, thus virtually wastes the exclusive performance of this kind of cable,
Improve the cost used.This armoured cable cover(ing) is also to be easy damaged position, although using the cable of steel-tape armouring
Performance is better than common cable, but in the actual use process, protecting tube is still socketed with outside armored cable, i.e.,
Lose the real value of armored cable.
Furthermore the maintenance of weak part cable or the replacement of entirety are also to have the regular hour to limit, in order to ensure electricity
The normal safe conveying of power, replacing the maintenance of cable or other modes must power off.
Protected working based on current cable weak part is also in traditional mode, with the increasing of national electricity demand
Add, power cable it is widely available, the defect of this kind of traditional working method is with protrusion gradually, for this purpose, being badly in need of a kind of new
Scheme replaces the mode of existing material and work.For this purpose, applicant proposed a kind of completely new technical solutions, and provide
A kind of cable protection band.
Invention content
Technical problem to be solved by the invention is to provide a kind of cable protection band and preparation method thereof, the cable protection bands
Outer enter ground cable protection method, update to being directly exposed to using metal sleeve or nonmetallic integral cannula instead of existing
With it is easy to maintain, reduce the cost of maintenance.
In order to solve the above technical problems, technical scheme of the present invention is mainly conceived from the following aspect：（1）In order to overcome entirety
The defect that sleeve structure is brought, the application uses the protection band of spiral winding mode, and is realized and operated by specific structure
Agility and convenience, and solve the performance of ventilative heat dissipation.（2）Easy to maintain in the later stage, the mode of wound form need not be whole
The more conversion materials of body, and the use that this kind of material can also repeat, can be by after cable self maintained, and carry out again is corresponding
Protection.（3）It finds in an experiment, since this kind of protection band is thicker, and limber requirement, deflection mistake in order to prevent
Greatly, the compound of different materials is used, to ensure under the premise of reliably winding power, limits excessive deformation.（4）Meanwhile
Enhancement layer also acts the performance for protecting itself tear-proof.（5）In terms of the raw material selection of interior rubber protective layer, mainly consider
The stability and resistance to ag(e)ing of material, and in the selection of outer rubber protective layer raw material, mainly other than basic performance, emphatically
Consider tensile strength, compressive deformation, stability etc..
Applicant passes through the modifications and adaptations in production method again, finally proposes technical solution below：
A kind of cable protection band includes the interior rubber protective layer bonded by adhesive and outer rubber protective layer, outer rubber protection
