Description
Technical field
This utility model relates to lead technology field, is specially a kind of multiply copper core plastic insulated conductor.
Background technology
The transmission of electricity realizes generally by electric wire, traditional insulated electric conductor outer layer generally comprise the flame retardant plastic bed of material with
Standard plastic layer, common plastic layer is typically easily damaged, and wear resistance compares wiping, and accident the most often can be caused to send out
Raw, sometimes wire short-circuiting, voltage over loading, the outside reason such as on fire cause electric wire on fire, and electric wire after-combustion on fire speed is non-
The fastest, if electric wire outer layer covers is that plastic layer is the most on fire, particularly on fire in the case of energising, country and people can be given
The people bring serious loss.
Utility model content
The purpose of this utility model is to provide a kind of multiply copper core plastic insulated conductor, to solve in above-mentioned background technology
The problem proposed.
For achieving the above object, this utility model following technical scheme of offer: a kind of multiply copper core plastic insulated conductor, bag
Including conductor, the circumferential inner wall of described conductor is provided with copper core, the outside of described conductor is provided with oxygen barrier layer, described oxygen barrier layer
Outside is glued with fireprotection layer, and the outer circumference of described fireprotection layer is provided with mica tape, and the outside of described mica tape connects insulation
Layer, the inside of described insulating barrier scribbles pvc coating, and the outside of described insulating barrier is provided with elastomer plastic refuge floor.
Preferably, the circle centre position of described conductor is provided with strengthening core and described copper core is close to the outer surface of strengthening core.
Preferably, described elastoplast refuge floor is that polyimides is made.
Preferably, the quantity of described copper core is 6 to 8.
Compared with prior art, the beneficial effects of the utility model are: this multiply copper core plastic insulated conductor, including 5 layers,
Being oxygen barrier layer, fireprotection layer, mica tape, insulating barrier and elastomer plastic refuge floor the most successively, mica tape is wrapped in fire prevention
The outer surface of layer, insulating barrier is wrapped in the outer surface of mica tape.Mica tape is a kind of insulating refractories, and fusing point is high, high temperature resistant
Effectiveness comparison is good, even mica tape also has good insulating properties under conditions of high temperature, what fireprotection layer can reduce electric wire can
Combustion property, stops the fast development of fire, by adding mica tape and fireprotection layer in electric wire, can improve the anti-of electric wire further
Fire, insulating properties and heat-resisting quantity, the outermost layer of electric wire is elastomer plastic refuge floor, owing to refuge floor uses high temperature resistant antifriction
Property plastics, so that wear resistance improves further, the service life of extending wire.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1 conductor, 2 copper core, 3 oxygen barrier layers, 4 fireprotection layers, 5 mica tapes, 6 insulating barriers, 7 polrvinyl chloride, 8 elastomers are moulded

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1, a kind of technical scheme of this utility model offer: a kind of multiply copper core plastic insulated conductor, including leading
Body 1, the circumferential inner wall of described conductor 1 is provided with copper core 2, and copper core 2 is arranged on the inner side of conductor 1, can strengthen electric conductivity, make
The electric conductivity obtaining wire is greatly improved, and the outside of described conductor 1 is arranged on outside copper core 2 equipped with oxygen barrier layer 3, oxygen barrier layer 3
Side, decomposing metal oxide and water of crystallization can form network structure rapidly when that oxygen barrier layer 3 running into high temperature, flue gas is had one
Fixed adsorption, soot not only can be played settlement action but also the most good heat absorptivity, significantly drop by the water of crystallization of precipitation
The incidence rate of low accident, the outside of described oxygen barrier layer 3 is glued with fireprotection layer 4, and fireprotection layer 4 can reduce the combustibility of electric wire, resistance
The only fast development of fire, the outer circumference of described fireprotection layer 4 is provided with mica tape 5, and the fusing point of mica tape 5 is high, high temperature resistant effect
Relatively good, even the situation in fire generation the most still has good insulating properties, can be improved by the mica tape 5 installed
The heat-resisting quantity of wire and insulating properties, the outside of described mica tape 5 connects insulating barrier 6, and the inside of described insulating barrier 6 scribbles poly-
Pvdc layer 7, polrvinyl chloride 7 cheap, processing formula can be simplified and improve yield rate, reducing the cost of buying, institute
The outside stating insulating barrier 6 is provided with elastomer plastic refuge floor 8, breaking out of fire when, due to high-temperature expansion, elastoplast
Refuge floor 8 can form the netted charring layer of asbestos, form a non-flammable charring layer, and the oxygen of prevention enters, and stops burning
Quickly spread, the circle centre position of described conductor 1 is provided with strengthening core 9 and described copper core 2 is close to the outer surface of strengthening core 9,
Strengthening core 9 is possible to prevent copper core to be bent excessively and the situation of fracture occurs, and increases the service life of wire, and described elasticity is moulded
Material refuge floor 8 is made for polyimides, and the quantity of described copper core 2 is 6 to 8.
This utility model is in the specific implementation: be provided with strengthening core 9, is possible to prevent copper core 2 to be bent and excessively occurs disconnected
Situation about splitting, energy decomposing metal oxide rapidly and precipitation water of crystallization when that oxygen barrier layer 3 running into high temperature, water of crystallization has very well
Heat absorptivity, fireprotection layer 4 can reduce the combustibility of electric wire, stops the fast development of fire, and mica tape 5 has resistance to height equally
Warm nature and insulating properties.
Embodiment the most of the present utility model, for the ordinary skill in the art,
It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair
