Abstract
The invention relates to a novel prefabricated branch cable which comprises a main cable, a branch cable and an outer sheath, wherein the main cable is penetrated in the outer sheath; one end of the branch cable is penetrated in the outer sheath and connected with the main cable; a conductor in the main cable is connected with a conductor in the branch cable through a C-shaped conductor connecting pipe by adopting a conductor cold pressing mode; and an insulating layer, an inner protective layer and a metal cladding layer are sequentially wrapped outside the conductors. In the invention, the connecting property of the main cable and the branch cable can be enhanced, the novel prefabricated branch cable has the advantages of small contact resistance, conductor oxidization avoidance, tightness, low environmental requirement, shock resistance, water proofing, fire resistance, low cost, and the like, and in addition, the longitudinal tensile force and the external mechanical damage resistance are also increased.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of branch cable, especially a kind of novel prefabricated branch cable.
Background technology
At present, prefabricated branch cable has two kinds of non-armouring list core and non-armouring multi-core branch cables, is applicable to that the rated voltage 0.6/1kV for building of air-laid and following supply main and tunnel, bridge are with illuminating line and other similar applications.Do not satisfy the requirement of buried-pipe laying (preventing the mechanical damage cable).In addition, in existing prefabricated branch cable,, reduce the effect of the cable transmission electric power or the information of transmission easily owing to the mechanical protection poor performance between main cable and the branch cable.
Summary of the invention
At the weak point that exists in the above-mentioned technology, the invention provides the more firm novel prefabricated branch cable of switching performance between a kind of main cable and the branch cable.
For achieving the above object, the invention provides a kind of novel prefabricated branch cable, constitute by main cable, branch cable and oversheath, described main cable is through the inside of described oversheath, one end of described branch cable is located in the inside of described oversheath and is connected with described main cable, and the conductor in the described main cable is crossed C shape conductor connecting tube with the conductor dbus in the described branch cable and adopted the conductor mode of colding pressing to be connected.
Be enclosed with insulating barrier, sheath and metal carbonyl coat successively in the described conductor outside.
Compared with prior art, the present invention has the following advantages:
The invention provides a kind of novel prefabricated branch cable, constitute by main cable, branch cable and oversheath, main cable is through the inside of oversheath, one end of branch cable is located in the inside of oversheath and is connected with main cable, conductor in the main cable is crossed C shape conductor connecting tube with the conductor dbus in the branch cable and is adopted the conductor mode of colding pressing to be connected, and is enclosed with insulating barrier, sheath and metal carbonyl coat successively in the conductor outside.The present invention can strengthen the switching performance between main cable and the branch cable, have contact resistance little, avoid having increased longitudinal pulling force and anti-extraneous mechanical damage ability outside the advantages such as conductor oxidation, tightness, environmental requirement are low, shock resistance, water proofing property, fire resistance, low cost.Low capacity bus duct during the present invention can replace is used for illuminators such as semi-high-rise housing building distribution system, sub-district, workshop building, the equipment of taking precautions against natural calamities, airport, railway, bridge, tunnel etc.

Embodiment
For clearer statement the present invention, the invention will be further described below in conjunction with accompanying drawing.
As shown in Figures 1 to 4, the invention provides a kind of novel prefabricated branch cable, be made of main cable 2, branch cable 3 and oversheath 1, main cable 2 is through the inside of oversheath 1, and an end of branch cable 3 is located in the inside of oversheath 1 and is connected with main cable 2.Wherein, the conductor in the main cable 2 and the conductor dbus in the branch cable are crossed C shape conductor connecting tube (describing among the figure) and are adopted the conductor mode of colding pressing to be connected.Be enclosed with insulating barrier 5, sheath 6 and metal carbonyl coat 7 successively in the outside of conductor 4.
The present invention uses through actual installation, owing to increased the metal armouring layer, effect is obvious.Can increase the metal armouring layer, improve the anti-extraneous mechanical damage and the disconnected ability of tension of product, guarantee product quality better.Can be used in the semi-high-rise housing building distribution system, advantage is more outstanding.The high energy of mill run is used 10～15 floor layer heights (supporting by cable conductor self stretching resistance), can use 30 floor layer heights after adopting this invention product.This product advantage that can also be used for buried-pipe laying is more, avoided because of the mechanical external force effect damages cable, thus the inherent quality of more effective assurance cable.
More than disclosed only be several specific embodiment of the present invention, still, the present invention is not limited thereto, any those skilled in the art can think variation all should fall into protection scope of the present invention.
Claims (2)
