Abstract
The invention discloses a prefabricated branched cable which comprises a main insulation cable core and a branch insulation cable core. A conductor of the main insulation cable core and a conductor of the branch insulation cable core are firmly connected together through one or more C-shaped copper piece connecting bodies. Tear-resistant LSOH polyolefin materials are used for conducting airtight mould pressing on the connecting bodies to form an injection body. The prefabricated branched cable is not influenced by thermal expansion and contraction, has excellent shock resistance, good airtightness and good waterproof performance, and is capable of supplying power normally in a moisture environment and also capable of being laid in the open air or laid underground. The prefabricated branched cable is small in occupied space, beneficial to effective using of building area and simple and convenient to mount, and has good social and economical benefits.
Description
Technical field
The invention belongs to power cable field, be specifically related to a kind of skyscraper place distribution system prefabricated branch cable.
Background technology
Along with society and expanding economy, the modern buildings such as high-rise, high-rise commercial residential building, office building are built in a large number, structure becomes increasingly complex, this also increases the complexity of building distribution system, the electricity capacity of single building building also sharply increases simultaneously, as still adopted the system of laying of traditional bus duct, be difficult to meet again above requirement.And a kind of novel cable---prefabricated branch cable has plurality of advantages, as: because work on the spot completes in manufacturing works, and install simple, cycle is short, thereby not only save working time of job site, and saved site operation labour, thereby make total architectural engineering expense comprise that the expense of personnel and material just compressed greatly; Erecting bed management is simple: prefabricated branch cable on treucher, makes on-the-spot easy for installation in advance.Therefore field management work, such as the arrangement of erection schedule, material requested obtain and storage etc. all can be saved; Airtight and water proofing property: the branch joint part of prefabricated branch cable is all airtight and waterproof, so branch cable both can be used for the area being dried, also can be used for humid region; Non-maintaining: prefabricated branch cable is after method is installed in accordance with regulations, the disposable height that takes up rate, the prefabricated band branch cable system of normal operation does not need to do maintaining at ordinary times.Because prefabricated branch cable it have that power supply safety is reliable, use cost is low, the advantage such as erection bay list, environmental requirement are low, non-maintaining, can meet well the demand of the modern society such as reduction and the reliability of power supply of build on-site to labour cost.
Summary of the invention
The object of this invention is to provide a kind ofly have that power supply safety is reliable, use cost is low, erection bay list, non-maintaining prefabricated branch cable.
A kind of prefabricated branch cable of the present invention, comprises main insulation core and branch's insulated wire cores, and the conductor of described main insulation core and the conductor dbus of branch insulated wire cores are crossed together with connector is firmly crimped on; Adopt again the airtight mold pressing of tear-proof type low-smoke halogen-free polyolefin material to form injection molding body at this connector place.
Further improve, described connector is firmly formed by connecting by the even crimping of 1-3 C type copper sheet.
Beneficial effect of the present invention is:
The cable of the present invention swollen shrinkage impact of not being heated, and there is good shock resistance, good air-tightness and water proofing property, normal power supply in a humid environment, also can be in the open and buried-pipe laying; This cable floor space is little, is conducive to effective use of construction area, installs simple and convenient; This cable has good social and economic benefits.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of prefabricated branch cable of the present invention, comprise main insulation core 1 and branch's insulated wire cores 2, the conductor of described main insulation core 1 and the conductor dbus of branch's insulated wire cores 2 are crossed the connector 3 being firmly formed by connecting by the even crimping of 1-3 C type copper sheet and are firmly linked together; Adopt again the airtight mold pressing of tear-proof type low-smoke halogen-free polyolefin material to form injection molding body 4 at these connector 3 places.
The conductor of described main insulation core 1 can adopt has the stranded steel structure that 10 filament diameters are 2.58mm; The conductor of described branch's insulated wire cores 2 can adopt has the stranded steel structure that 7 filament diameters are 1.35mm.
The invention provides a kind of prefabricated branch cable; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improve and also should be considered as protection scope of the present invention.
