Description
Technical field
The utility model relates to cable technology field, and a kind of cooling cable of double shield layer 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.
Produced in the world Article 1 lv power cable (the wrapped copper conductor of rubber belt) 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, 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
