Abstract
The utility model discloses a prefabricated branch cable, which makes improvement and breakthrough on the problems of the prior art of difficult cable assembly, excessively high cost and potential safety hazard, and comprises a principal line cable and a branch cable, and the principal line cable and the branch cable are connected and communicated through branch joint in the joint. The prefabricated branch cable of the structure replaces the prior expensive bus duct, reduces greatly the construction cost and is provided with excellent reliability of safe power supply; the utility model has the advantages of low requirement for construction environment, small occupation area and small bending radius, which is convenient for the construction cable assembly, shortens the construction time and reduces the labor intensity; the utility model also has the water-proof and damp-proof functions, therefore long-term maintenance-free operation can be realized.
Description
Technical field
The utility model relates to a kind of cable, particularly a kind of prefabricated branch cable.
Background technology
Along with the high speed development of economic construction and improving constantly of industrial degree, skyscraper and large-scale public place construction are more and more, the power consumption in the building and the complexity of circuit cable also increase greatly, make the distribution in the building more and more difficult, therefore, the winding displacement of building power distribution circuit becomes a big problem of people's growing interest and attention, especially at construction site, the reduction of distribution cost, reduce lay take up room, the reliability of the shortening of construction period and power supply becomes the consistent strong request of the investor and builder and power supply department.Though can solve branch problem in the distribution with traditional bus duct, there are many inadequate natural endowments in bus duct, as use that inconvenience, project cost cost are too high, hidden danger etc.
The utility model content
For overcoming above-mentioned defective, the utility model purpose is to provide a kind of prefabricated branch cable, the too high and potential safety hazard proposition improvement breakthrough at winding displacement difficulty, the cost of prior art existence.
For achieving the above object, prefabricated branch cable of the present utility model comprises backbone cable and branch cable, and described backbone cable is connected conducting with branch cable by the branch joint in branch's connected body.
Prefabricated branch cable of the present utility model has substituted the bus duct that involved great expense originally, greatly reduces project cost, has good safe power supply reliability; Low to the construction environment requirement, floor space is little, and bending radius is little, is convenient to the winding displacement of constructing, and has shortened the engineering time, has reduced labour intensity; Have waterproof and dampproof function, can be non-maintaining for a long time, exempt from maintenance.
Description of drawings
Fig. 1 is the structural representation of the utility model prefabricated branch cable.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, prefabricated branch cable of the present utility model comprises backbone cable 1 and branch cable 2, and backbone cable 1 is connected conducting with branch cable 2 by the branch joint 8 in branch's connected body 3.The prefabricated branch cable of said structure has substituted the bus duct that involved great expense originally, greatly reduces project cost, has good safe power supply reliability; Low to the construction environment requirement, floor space is little, and bending radius is little, is convenient to the winding displacement of constructing, and has shortened the engineering time, has reduced labour intensity; Have waterproof and dampproof function, can be non-maintaining for a long time, exempt from maintenance.
Further, backbone cable 1 comprises center conductor 4, and is outside from center conductor 4, is coated with flame retardant coating 5, insulating barrier 6 and oversheath 7 successively.
Further, branch cable 2 comprises center conductor 4, and is outside from center conductor 4, is coated with flame retardant coating 5, insulating barrier 6 and oversheath 7 successively.
The insulating material of above-mentioned insulating barrier 6 adopts one-step silane cross-linked polyethylene, and flame retardant coating 5 adopts synthetic mica tape or phlogopite band, has increased fire resistance on the basis of possessing good electrical property of insulating material and physical property.Can work under the category-B grade flame temperature of 950～1000 ℃ category-A grade flame temperature or 750～800 ℃, the operating time all reaches more than the 90min.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of described claim.
