Abstract
The utility model provides a branch wire cable for electric line distribution, which is characterized in that a plurality of leads consist of metal conductors of a main trunk; furthermore, an insulation layer and a protection layer are arranged; a plurality of leads are freely taken at a plurality of positions in any distance of the main trunk and branch leads are led-out or led-in by a sealing head; the cross-section of the conductor at the head and the tail of the main trunk or the core number of the insulation wire core can be identical, increased or reduced; the branches of the main trunk and the branch leads are respectively provided with fixing parts; the combination position of the main trunk and the branch line has no connecting points.
Description
Technical field
The utility model relates to the electric wire field, belongs to the electric wiring distribution specifically and replaces the bus duct distribution or pay the electric wire of formula distribution in advance.
Background technology
Present used electrical power distribution system in skyscraper, tunnel, subway, if circuit generally adopts bus duct and pays the formula branch cable in advance and satisfy requirement of engineering when needing to adopt branch's form.But these two kinds of modes all exist branch line and backbone that the problem of contact-making surface is arranged, and unavoidably bring connection reliability and the cold and hot performance issue of more unmanageable overcurrent.
Summary of the invention
It is as a whole that the purpose of this utility model provides a kind of breakout cable and trunk cable of electric wire electric wiring distribution, can once form at production line, backbone and branch line place contactless, backbone and branch line are a complete integrally-built branch wire cable.
For finishing above-mentioned technical scheme that goal of the invention is taked: in the backbone of electric wire, establish many metallic conductors and form corresponding some leads, and establish sheath and insulating barrier, the many places any distance is got some leads arbitrarily and is drawn offset by end socket in its backbone, and backbone continues to extend, the insulating core number of backbone head and afterbody is identical, its offset is provided with sheath and insulating barrier equally, and the bifurcation of backbone and branch line is provided with fixture respectively on lead.The branch line that above-mentioned backbone is drawn in variant distance can make backbone insulating core number reduce, and backbone is provided with the insulating core number at any distance contactless by end socket and introduces the increase that branch line forms the insulating core number of backbone simultaneously.
Relatively poor and the expensive bus duct distribution of the utility model alternative security performance in the application of skyscraper electrical power distribution, simultaneously contactless electric property is better than the prefabricated branch cable greatly, for this reason the utility model in the tunnel, subway and explosion-proof environment occasion can both be used widely.
The utility model embodiment is described in detail in conjunction with the accompanying drawings.
Description of drawings
Fig. 1 is equal to core table structure figure for the utility model branch trunk lead;
Fig. 2 is that the utility model backbone conductor cores number reduces structure chart.
Embodiment
According to Fig. 1, establish many metallic conductors (6) in the backbone (1) and form corresponding some leads (4) and establish insulating barrier and sheath (5), the many places any distance of backbone (1) and get some leads (4) arbitrarily and draw offset (4) by end socket (3) simultaneously.This lead (4) continues to extend in backbone (1), the head of backbone (1) is identical with the insulating core number of afterbody, cross-sectional area of conductor is identical, the offset that is stretched out (4) is provided with insulating barrier and sheath (5) equally, backbone (1) is provided with fixed body (7) at lead (4) respectively with bifurcation, makes whole wire cable solid and reliable.
Embodiment two: as shown in Figure 2, backbone (1) can be drawn branch line (2) in different distances, and its conductor (4) no longer continues to extend in backbone (1), and the insulating core number of backbone (1) reduces gradually, the sectional area of conductor reduces equally, and other technologies are all identical with above-mentioned example.
Embodiment three: opposite with example two, backbone (1) is provided with the insulating core number at any distance contactless by end socket (3) and introduces branch line (2), makes the insulating core number of backbone (1) increase the corresponding increase in the cross section of conductor.
Claims (3)
1; a kind of lead of forming by metallic conductor; the spontaneous formula branch wire cable that protective layer and insulating barrier constitute; it is characterized in that establishing in the backbone (1) many metallic conductors (6) forms corresponding some leads (4) and establishes sheath and insulating barrier (5); the many places any distance is got some leads (4) arbitrarily and is drawn offset (4) and continuation extension in backbone (1) by end socket (3) in the above-mentioned backbone (1); the conductor insulation core core number of backbone (1) head and afterbody is identical; its offset (4) is provided with sheath and insulating barrier (5) equally, and backbone (1) is provided with fixture (7) respectively with the bifurcation of branch line (2) on lead (4).
2, spontaneous formula branch wire cable according to claim 1 is characterized in that branch line (2) back that backbone (1) is drawn in variant distance forms the minimizing of backbone (1) insulating core number.
3, spontaneous formula branch wire cable according to claim 1 is characterized in that backbone (1) is provided with the insulating core number at any contactless by end socket (3) and introduces the insulating core number increase that branch line (2) forms backbone (1).
