Abstract
The utility model relates to a multi-core prefabricated branch cable which is composed of a main cable, branch cables, and an outer insulating protective sleeve. In the utility model, at least two branch cables branch from each user terminal of the main cable; a crotch is tightly compressed and fixed by a connecting piece; all the conductors of the main cable and the branch cables are separated from each other in an insulating manner; sealing and integral injection moulding are carried out on the main cable, the branch cables, and the connecting piece by the outer insulating protective sleeve at a separation point; as a result, a tree-shaped structure in which a truck has branches is formed. Prefabricated in the factories, the cable has the advantages of good sealing performance, good reliability for power supply, low price, convenient installation, and small floor area in site construction. The utility model can be used in power supply systems of various buildings.
Description
The utility model relates to the transmission of a kind of supply line or distributes the cable of electric energy.
Existing supply line cable has common cable, enclosed busbar groove.Common cable branch difficulty, leader cable is connected at the construction field (site) by hand with branch cable, engineering time is long, be prone to the seal failure point, joint copper core exposes for a long time in air, easily produces oxidation and causes contact resistance to change, and quality can't guarantee, rate of failure also causes cable waste and circuit confusion easily than higher in the installation.And easily there are a large amount of electric connecting points of low quality in the enclosed busbar groove, and price is higher.
The purpose of this utility model provides a kind of multicore prefabricated branch cable of millwork production, saves site operation labour and engineering cost, and is easy for installation, and low price guarantees power supply quality.
The technical scheme of the utility model multicore prefabricated branch cable: this cable is made up of leader cable, branch cable and insulating protection overcoat, it is characterized in that: leader cable is told at least two branch cables at each user side, crotch is fixed with the connector tight compression, insulation is isolated between each conductor of leader cable and branch cable, insulating protection is enclosed within separation place outward leader cable, branch cable, connector sealing is injection molded into one, forms the tree structure that trunk is told Zhi Gan.
Above-mentioned connector is a C type connector.
Above-mentioned leader cable is told four branch cables at each user side, constitutes the three-phase and four-line structure of a leader cable and four branch cables.
Isolate with inner sheath or with insulating bag band electric insulation between above-mentioned each conductor.
Above-mentioned tree structure can be that a place or two places concentrate and tell Zhi Gan on trunk, also can tell Zhi Gan one by one on trunk.
The course of work of the present utility model: whole cable is prefabricated in the factory, only need the logical hoist engine of a Daepori during installation and on drum, it is fixing that the cable upper end is promoted on the building top layer crossbeam hook, each floor throws away four branch cables, be connected with distribution box, midway fixing with expansion bolt or saddle wire clamp of cable, the lower end of cable is connected with power supply.
The utility model has the advantages that: main cable conductor non junction, reduced the fault point, branch joint factory entire mechanization is made, and electrical insulation properties is good, and contact resistance is little, and the power supply reliability height is not affected by thermal expansion and contraction; Compare with bus duct, can reduce project cost, overall economic efficiency is remarkable; Installation period is short, is 1/10 to 1/20 of bus duct installation work-hour, and it is little that labour intensity is installed, and do not need maintaining at ordinary times.Whole solitary building has only a leader cable from top to bottom, and branch cable does not need on-the-spot joint and sealing, and installing space is little, save working time and labour, and this cable has good air-tightness and water resistance, does not need moistureproof the processing.Can be applicable to various architectural engineerings such as skyscraper, factory floor, road and bridge.
Below in conjunction with drawings and Examples the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is an outline drawing of the present utility model;
Fig. 4 is the end view of Fig. 3;
Fig. 5 is the vertical view of Fig. 3;
Fig. 6 is the upward view of Fig. 3.
Embodiment one: as shown in Figure 1, the utility model multicore prefabricated branch cable is by leader cable 1, branch cable 5 and insulating protection overcoat 2 are formed, it is characterized in that: leader cable 1 is told at least two branch cables 5 at each user side, crotch is fixed with C type connector 3 tight compression, isolate with inner sheath or with insulating bag band 4 electric insulations between each conductor of leader cable and branch cable, insulating protection overcoat 2 in separation place with leader cable, branch cable, the connector sealing is injection molded into one, form trunk and tell the tree structure of Zhi Gan, tree structure can be that a place or two places concentrate and tell Zhi Gan on trunk, also can tell Zhi Gan one by one on trunk.Leader cable is generally told four branch cables at each user side, constitutes the three-phase and four-line structure of a leader cable and four branch cables.
