Description
【Technical field】
Field of cable technology is the utility model is related to, more particularly to a kind of cold-resistant electricity of anti-ice used on power network line
Cable.
【Background technology】
The carrier that cable transports as electric power, vital effect is played in the electric power transport of equipment, so cable
Quality safety and service life largely effect on the safety and quality of people's lives.Once a snow calamity just made southern large area
Tower collapse, industrial and agricultural production loss reach hundreds of millions of.Go into seriously collapse of iron tower because covering because power network is without " self shake " work(
Can, so that the ice slush being attached on line cord is in the case where southern humidity is sombre, it is constantly thicker to grow up.Finally, cable is not
In the case of bearing heavy burden, side cable is broken suddenly, and opposite side overweight pulling force moment just forgets about it power tower.
Used high voltage electricity transmission conductive wire is the twisted cable of copper (aluminium) silk, although such cable has conduction well
Performance, but tensile capacity is poor.And naked twisted wire product is mainly set up in the wild in the air, if running into heavy snow celestial pole in winter
Easily freezing makes load exceed itself suffered limit and be broken, and this is huge to the influence that cable run is brought, especially for electricity
Higher ranked cable is pressed, the consequence brought is hardly imaginable, and huge hidden danger is brought to Electrical Safety.
【Utility model content】
The purpose of this utility model is to provide a kind of anti-ice cold resistant cable that can effectively overcome above mentioned problem to occur, and it is anti-
Drawing ability is strong, and extreme environment stability inferior is good, service life length.
What the purpose of this utility model was realized in：It includes a hollow insulation and restrictive coating and core, the line
Core includes the first wire body, the second wire body and screen layer, and first wire body includes one or more tension single line, the tension
Single line is twisted to form first wire body, and second wire body includes more conductive single lines, the twisted bag of the more conductive single lines
The external side face of the First Line is rolled in, the screen layer is between the core and the insulation and restrictive coating.
In said structure, first wire body includes more tension single lines, and the core is stranded in by second wire body
The external side face of First Line presses shaping jointly.
In said structure, the polymeric barrier layer materials are TPO semiconductive shieldin material.
In said structure, the tension single line is one or more of materials composition of copper, aluminium, steel.
In said structure, the conductive single line is copper cash, aluminum steel, steel wire or alloy wire.
In said structure, the insulation and restrictive coating are crosslinked polyolefin material, polyvinyl chloride or rubber.
Core of the present utility model is made up of two parts inside and outside the first wire body and the second wire body, and the first wire body is that high tensile is strong
Material is spent, outside second wire body is high conductive material, both ensure that the requirement of cable conduction performance, and had greatly improved cable again
Tension cutting capacity, avoid cable from freezing and be pulled off, substantially increase the security performance and service life of cable.It is provided with simultaneously
Insulation and restrictive coating and shielding layer structure, the anti-ice water resistance of this materials at two layers is good, and being coated on outside core effectively to avoid
Sleet contacts conductor, prevents conductor freezes from increasing cable deadweight, adds anti-ice performance.
