In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an aluminium strip armor polyethylene insulated cable, includes the conductor, and the conductor includes the aluminium core, and the fixed parcel of outside wall of aluminium core has first shielding layer, and the outside wall parcel of first shielding layer has the polyethylene insulating layer, and the outside wall parcel of conductor has the second shielding layer, and the outside wall parcel of second shielding layer has the aluminium strip armor, and the outside wall parcel of aluminium strip armor has the outer insulating layer, and the outside wall parcel of outer insulating layer has compound insulating layer.
Preferably, a filling fiber layer is filled between the second shielding layer and the conductor.
Preferably, a reinforcing core is arranged between the filling fiber layers.
Preferably, the number of conductors is three, and the mounting position of the reinforcing core is located between the three groups of conductors.
Preferably, the aluminum core is stranded from a plurality of aluminum strands.
Compared with the prior art, the beneficial effects of the utility model are that: it has the packing fibrous layer to fill between second shielding layer and conductor, can place the cable not hard up and lead to the friction damage, and the outer composite insulation layer of addding effectively delays the rise of inside cable during operation temperature, effectively protects inside aluminium strip armor and outer insulating layer for cable surface temperature is unlikely to too high, promotes the work efficiency of cable.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the cable comprises a conductor, 11, an aluminum core, 12, a first shielding layer, 13, a polyethylene insulating layer, 2, a second shielding layer, 3, an aluminum tape armor layer, 4, an outer insulating layer, 5, a composite heat-insulating layer, 6, a filling fiber layer, 7, a reinforcing core, 8 and an aluminum wire bundle.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: an aluminum tape armored polyethylene insulated cable comprises a conductor 1, wherein the conductor 1 comprises an aluminum core 11, the outer side wall surface of the aluminum core 11 is fixedly wrapped with a first shielding layer 12, the outer side wall surface of the first shielding layer 12 is wrapped with a polyethylene insulating layer 13, the outer side wall surface of the conductor 1 is wrapped with a second shielding layer 2, the outer side wall surface of the second shielding layer 2 is wrapped with an aluminum tape armored layer 3, the outer side wall surface of the aluminum tape armored layer 3 is wrapped with an outer insulating layer 4, the outer side wall surface of the outer insulating layer 4 is wrapped with a composite insulating layer 5, the aluminum core 11 is wrapped in the first shielding layer 12 and the polyethylene insulating layer 13, the surface of the uniform wire core is uniformly electrically non-uniform, so that mutual influence is prevented when a plurality of aluminum cores 11 are electrified to work, meanwhile, air gaps are not generated between the first shielding layer 12 and the polyethylene insulating layer 13, the discharge voltage of the cable is improved, a filling fiber layer 6 is filled between the second shielding layer 12 and the conductor 1, can place the cable not hard up and lead to the friction damage, the rising of inside cable during operation temperature is effectively delayed to outer composite insulation layer 5 of addding, effectively protects inside aluminium strip armor 3 and outer insulation layer 4 for cable surface temperature is unlikely to too high, promotes the work efficiency of cable.
Specifically, the filling fiber layer 6 is filled between the second shielding layer 2 and the conductor 1, and the filling fiber layer 6 is filled between the second shielding layer 12 and the conductor 1, so that the cable can be prevented from being loosened and causing friction damage.
Particularly, install reinforcing core 7 between the packing fibrous layer 6, reinforcing core 7 is used for making the cable have better holding power, is difficult for forming the bending of less angle to difficult the bending damage that causes the cable.
Specifically, the number of the conductors 1 is three, and the mounting position of the reinforcing core 7 is located between the three sets of the conductors 1, and the three sets of the conductors 1 perform better work.
Specifically, the aluminum core 11 is twisted from a plurality of aluminum strands 8 to provide a working channel for the cable.
The working principle is as follows: when using, form aluminium core 11 by 8 transposition of aluminium silk bundle, by the inside of parcel at first shielding layer 12 and polyethylene insulating layer 13, the even effect of even sinle silk uneven electricity in surface, produce the interact when preventing a plurality of aluminium cores 11 circular telegram work, tight parcel simultaneously, make not produce the air gap between first shielding layer 12 and the polyethylene insulating layer 13, the discharge voltage of this cable has been improved, it has filling fibrous layer 6 to fill between second shielding layer 12 and conductor 1, can place the cable and become flexible and lead to the friction damage, the outer compound insulating layer 5 that adds effectively delays the rising of inside cable during operation temperature, effectively protect inside aluminium strip armor 3 and outer insulating layer 4, make the cable surface temperature unlikely to too high, promote the work efficiency of cable.
