Insulating layers (2) wrap the conductors (1), the inner shielding layers (4) wrap the insulating layers, the outer shielding layer (6) wraps the inner shielding layers (4), an outer jacket (7) wraps the outer shielding layer, a ventilating layer (8) wraps the outer jacket (7) and is of a hollow structure, air holes (9) are formed in the ventilating layer (8), inner fillers (3) are arranged between the insulating layers (2) and the inner shielding layers (4), and outer fillers (5) are arranged between the inner shielding layers (4) and the outer shielding layer (6).
Description
Technical field
The present invention relates to field of cable technology, provide a kind of double shield stratotype cooling cable.
Background technology
Existing cable cooling capacity is poor, and the screening ability of existing cable is bad, and diamagnetic field energy power is weak, and antistatic effect is poor.
Produced Article 1 lv power cable (the wrapped copper conductor of rubber belt) in the world from 1836 so far, electric wire has developed into a large product category of many uses, various in style.China's wires and cables industry, through the development of more than 70 years, also achieves larger progress.Along with Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.State-owned and the above enterprise of scale about 5000 of current China wires and cables industry, wherein large enterprise has 19, and the gross output value accounts for 11% of whole market share.
Electric wire is the conveying energy, the indispensable basic equipment of transmission of information, and from the today in social informatization, electrified fast development, electric wire has become one of most important basic product in economic construction.Wires and cables industry is again supporting industry, and product must meet each main industry of national economy to the requirement of electric wire performance, and national economy thinks that most industry is all relevant to electric wire, and its industrial status is very important.China's wires and cables industry is still in developing stage at present, and as the important guide's industry of the development of the national economy, the growth of electric wire production and marketing index is generally higher than total value of production in national economy outline.
Summary of the invention
The object of the present invention is to provide a kind of cooling capacity good, the double shield stratotype cooling cable that anti-shielding ability is strong.
To achieve these goals by the following technical solutions:
A kind of double shield stratotype cooling cable, it is characterized in that, comprise single cable, single cable comprises conductor 1, conductor 1 outer wrapping insulating barrier 2, at least 2 single cable are wrapped to form sub-thread shielded type cable by an internal shield 4, at least 2 sub-thread shielded type cables are wrapped up by an outer shielding layer 6, outer shielding layer is wrapped with oversheath 7, outer family cover 8 is wrapped with ventilating layer 8, described ventilating layer 8 is hollow structure, and ventilating layer 8 is provided with air vent hole 9, interior filler 3 is provided with between described insulating barrier 3 and internal shield 4, outer filler 5 is provided with between described internal shield 4 and outer shielding layer 6.
In technique scheme, described interior filler 3 is nonwoven fabrics.
In technique scheme, described outer filler 5 is fireproof water-resisting tape, and it comprises mica layer, and mica layer two sides is adhering glass fiber mesh respectively, and the film that bonding one deck is made up of water-proofing powder on fiberglass gridding forms water blocking layer.
In technique scheme, described internal shield 4 and outer shielding layer 6 all adopt layers of copper, and described layers of copper is evenly equipped with through hole.There is not crust bulge when avoiding and using tinsel braiding machine the Shields of Braided Cables layer or prick the problem of threading core in this structure.
In technique scheme, described insulating barrier 2 material is polyethylene or polyolefin.
The present invention is because adopt above technical scheme so possess following beneficial effect:
Therefore the present invention possesses strong, the antistatic interference of diamagnetic field energy power, anti-RF capabilities is strong, the advantage of fire-resistant waterproof.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
