Description

A kind of aluminium alloy shielding photovoltaic cable

Technical field

This utility model relates to field of cables, particularly relates to a kind of aluminium alloy shielding photovoltaic cable.

Background technology

At present, development along with science and technology, the demand of cable is also got more and more by people, cable is a kind of common data signal transmission equipment, there is message capacity big, the advantages such as transmission stability height is good with security performance, but existing cable covering is short for not only service life, and can there is the situation of contaminated environment, and existing cable is because of its working environment complexity variation, in cable work process, the external world there will be some stronger electromagnetic waves and it disturbed, cause cable that unsure state occurs in transmitting procedure, cause signal to external leakage, very big loss is brought to enterprise.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of aluminium alloy shielding photovoltaic cable.

This utility model takes techniques below scheme to realize: a kind of aluminium alloy shielding photovoltaic cable, it includes cable body, and described cable body includes conductor, insulating barrier, flame-retardant layer and oversheath, and described cable body is internally provided with multiple conductor；And described conductor outer wrap layer protective layer；Described protective layer and conductor collectively form cable core；Described cable body is internally provided with multiple cable core；And connected by isolation mount between described cable core；One layer insulating is set outside described cable core；One layer of lock armo layer is extruded outside described insulating barrier；One layer of flame-retardant layer is extruded outside described lock armo layer；One layer of sun-proof layer is extruded outside described flame-retardant layer；One layer of flame resistant protective layer is extruded outside described sun-proof layer；One layer of inner sheath is extruded outside described flame resistant protective layer；One layer of oversheath is extruded outside described inner sheath.

Above-mentioned a kind of aluminium alloy shielding photovoltaic cable, described conductor adopts many aluminium alloy wires to press stranded forming.

Above-mentioned a kind of aluminium alloy shielding photovoltaic cable, described flame-retardant layer adopts cross-linking radiation polyolefine material to extrude and forms.

Above-mentioned a kind of aluminium alloy shielding photovoltaic cable, described flame resistant protective layer adopts crosslinked polyethylene elastomeric material to make.

Above-mentioned a kind of aluminium alloy shielding photovoltaic cable, described inner sheath and oversheath are that polythene material is made.

This utility model has the advantages that this utility model has that reasonable in design, anti-jamming effectiveness be good and the advantage such as long service life in sum, described inner sheath and oversheath are that polythene material is made, there is good corrosion resistance and water vapor performance, and dielectric strength is high, substantially increase the service life of cable body.
