Description
Technical field
The utility model relates to cable technology field, and a kind of cooling cable is provided.
Background technology
Cable all plays extremely important effect as the main media of modern communication in all trades and professions, thus the barrier propterty of cable more and more paid attention to, especially cable cooling protection at high temperature.
From 1836, produce in the world Article 1 lv power cable (the wrapped copper conductor of rubber belt) 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, has also been obtained larger progress.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.At present approximately 5000 of the state-owned and above enterprises of scale of China's wires and cables industry, wherein large enterprise has 19, and the gross output value accounts for 11% of whole market share.
Electric wire is to carry the 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 the requirement of the each main industry of national economy to electric wire performance, and national economy thinks that most industries are 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 shielding properties strong, the one cooling cable that heat-resisting ability is good.
To achieve these goals, the utility model is by the following technical solutions:
A kind of cooling cable, its spy is, comprise sub-thread cable, sub-thread cable comprises at least 3 conductors 1, the outer all wrap insulate layers 2 of conductor, at least 2 sub-thread cables are wrapped to form sub-thread shielded type cable by internal shield, filler 3 is filled in gap between internal shield and sub-thread cable, internal shield outer wrapping outer shielding layer 4, outer shielding layer 4 outer wrapping anti-corrosion asphalts 5, anti-corrosion asphalt 5 outer wrapping inner restrictive coatings 6, inner restrictive coating 6 outer wrapping external sheath layers 7, uniform radiating tube 8 in external sheath layer, is provided with cooled with liquid nitrogen agent in radiating tube.
Described filling filler 7 is fireproof water-resisting tape, and it comprises mica layer, and mica layer two sides is the strengthening course of adhering glass fiber mesh establishment respectively, and the film that bonding one deck consists of water-proofing powder on strengthening course forms water blocking layer.
Described filling filler 7 is glass fibre.
The utility model adopts peripheral hardware cooling water pipe, inside establishes fireproof water-resisting tape, and its refractory ability is strong.
The utility model arranges interior outer shielding layer, and its shield effectiveness is good.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
