Abstract
The utility model discloses a kind of fixed wiring linkage armored cables, with multiple annealing circular copper wire conductor thread cores, each conductor thread core is coated with insulating layer, it is sequentially coated with high temperature resistance polyester belt and the chain armor of aluminium alloy outside multiple annealing circular copper wire conductor thread cores, there are annular gap between the chain armor of aluminium alloy and high temperature resistance polyester belt.The insulating layer is preferably cross-linked polyethylene layer or polyvinyl chloride layer.The utility model can effectively prevent flame to enter inside cable, and insulated wire cores is avoided to be burnt, and provide reliable electric power safeguard for fire-fighting and rescue and personnel escape, while the utility model compressive resistance and impact force are preferable, cable is not easy to be destroyed.
Description
Technical field
The utility model relates to a kind of fixed wiring cables, concretely relate to a kind of chain armouring of fixed wiring
Cable.
Background technique
In recent years, the burst fire in the large size such as place of public amusement, chemical industry, house, mall place causes heaviness
The heavy losses of people's life and property, so that people is offseted anti-, fire safety more deep understanding.How in burst fire
In the case where calamity, ensure within a certain period of time electric power and communication it is unimpeded, try to gain time precious to one to greatest extent, reduction personnel
Injures and deaths and lives and properties loss, this is people always in continuous the problem of exploring.
Currently, fixed wiring cable in the market, structure is insulating mainly in conductor thread core outsourcing insulating layer coating
The outer rubber-coated again or plastic sheath of layer, guarantees that fixed wiring has preferable bending property, to adapt to different building structure
Bending requirement, therefore the fixed wiring cable of the above-mentioned prior art does not have fire protecting performance, when a fire, electric wire electricity
Cable, which is easy to be burnt, in turn results in that line short is on fire, thus the generation for the even tragedy of resulting in greater loss.
Utility model content
The technical problem to be solved by the present invention is to provide it is a kind of i.e. with good bending property, fire resistant flame retardant again
Fixed wiring linkage armored cable.
In order to solve the above technical problems, the fixed wiring linkage armored cable of the utility model, has multiple annealing circle
Copper conductors core, each conductor thread core are coated with insulating layer, are sequentially coated with outside multiple annealing circular copper wire conductor thread cores resistance to
High-temperature polyester belt and the chain armor of aluminium alloy, there are annulus between the chain armor of aluminium alloy and high temperature resistance polyester belt
Gap.
The insulating layer is preferably cross-linked polyethylene layer or polyvinyl chloride layer.
Fixed wiring linkage armored cable using the above structure, due to outside multiple annealing circular copper wire conductor thread cores sequentially
It is coated with high temperature resistance polyester belt and the chain armor of aluminium alloy, therefore effectively flame can be prevented to enter cable when a fire
Inside avoids insulated wire cores from being burnt, and then guarantees the lasting safe operation of route, provides for fire-fighting and rescue and personnel escape
Reliable electric power safeguard.There are behind annular gap between the chain armor of aluminium alloy and high temperature resistance polyester belt, even if cable
When by biggish pressure and impact force, cable is also not easy to be destroyed, and improves security performance.In addition, compared to around packet mode
Armouring mode, the chain sheathed structure of aluminium alloy not only substantially increase the bending property of cable, make the laid processes of cable more
Convenient, laying occasion more multi-panel, and compared to the cable installation in pipe mode of most of fixed wirings, this patent is without wearing
Pipe can directly be laid, and then significantly improve mounting and installation efficiency.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is a kind of the schematic diagram of the section structure of fixed wiring linkage armored cable of the utility model.
Specific embodiment
Referring to Fig. 1, a kind of fixed wiring linkage armored cable of the utility model has multiple annealing circular copper wire conductor lines
Core 1, each conductor thread core 1 are coated with insulating layer 2, and it is poly- to be sequentially coated with high temperature resistant outside multiple annealing circular copper wire conductor thread cores 1
Ester belt 3 and the chain armor 4 of aluminium alloy, there are annular gap between the chain armor 4 of aluminium alloy and high temperature resistance polyester belt 3
5.The insulating layer 2 is cross-linked polyethylene layer or polyvinyl chloride layer.
