The cable industry is developing in an eco-friendly way

In recent years, the manufacturing scale of China's cable industry has increased rapidly, developed extensively, and expanded in an irrational manner. However, technological progress and product upgrades are slow, and homogenous competition is serious, resulting in serious overcapacity in the entire industry. In order to change such a status quo and realize the sustainable development of the enterprise, it is imperative to upgrade and upgrade. In 2014, China’s domestic cable industry was under pressure and its competition mainly came from the market and foreign-funded enterprises. The demands of the market are increasing. The injection of foreign capital is getting bigger and bigger, and various standards emerge in an endless stream. How can we not only meet the challenges but also become the leader and creator of the rules of the game? This is not an easy task.

At present, China’s mid- to low-end cable product overcapacity still exists, but the high-end cable product market has insufficient domestic supply. China’s high-end products each year rely on imports of 6 billion yuan. For a long time, China's cable manufacturing companies are in the midst of poor competition in the low-end market, and profit margins continue to be squeezed. The lucrative profits of high-end cables have attracted more and more companies to constantly try to produce. However, for most high-end cables, the domestic production capacity and supply are far from meeting actual demand.

This is mainly because the technological gap can not meet the domestic standards for high-end cable product requirements. At present, most domestic high-end cable markets are occupied by foreign companies such as Nexans and Prysmian. For example, cables and cables used in the aerospace industry and cables for high-end electrical equipment in China are highly demanding for wire and cable. It must be ensured that during the use of high-end electrical equipment, the cable's data communication capabilities and transmission capabilities can quickly meet equipment requirements. Therefore, China's 6 billion yuan per year of high-end cable must rely on imports.

However, the status of the industry is improving. In 2014, the development of cable products is showing four trends: ecology, environmental protection, specialization, high pressure, ultra-high pressure and refinement.

First, ecology, environmental protection Information revealed from the "two sessions" this year shows that: Environmental protection products will be the general trend of the future. Last year, with the EU's promulgation of the ROHS Directive, the development and large-scale adoption of eco-friendly wire and cable has become an international trend. At present, the application of fire-retardant and fire-resistant cables at home and abroad has been expanded to many fields. For example, mining, general-purpose rubber cable, elevator cables, and cables for household appliances all have different degrees of flame-retardant requirements.

Nowadays, key cities such as Beijing and Shanghai have stipulated that: It is forbidden to use polyvinyl chloride wire and cable in important buildings to avoid heavy smoke and chlorine at the time of fire, causing more casualties. The adoption of halogen-free low-smoke cross-linked polyolefin insulated wire and cable has become a local regulation in these areas. With the increase in people's awareness of environmental protection and safety, eco-friendly cables will be the product direction for future industry development.

In addition, it can not be ignored is that the vast majority of domestic major projects, projects for the product's primary requirement is environmental protection. As an important supporting facility for economic construction, cable products are unquestionable as they are going toward environmental protection.

Second, the specialization of the domestic cable industry shouted to "occupy the high-end market," occupying the high-end market can basically be said to occupy the special cable market. As the current special cable threshold is higher, the profit rate is higher and the competition is milder, so the high-end market is undoubtedly a visible “big fat” in front of the domestic cable industry, but it can only be eaten or, in the end, there are several Home companies can eat and get a question mark.

The so-called wire and cable product specialization is relative to the ordinary wire and cable, its relative performance is more superior, more able to adapt to special circumstances, with special uses. If the Far East cable meets the requirements of fire resistance, a porcelain-based silicon rubber that can be used in frequently bending and moving applications is successfully developed. The new type of highly efficient fire-resistant cable is successfully developed and can be used normally within 180°C. , Maintaining normal power supply within 1000°C, at the same time, the cable also has the characteristics of resistance to distortion; Silver Nonferrous International Co., Ltd. developed the 115m superconducting cable stranding cable for international thermonuclear fusion; Changfeng Group has developed and possessed independent knowledge. The property rights are completely replaceable in the composite high-conductivity aluminum alloy power cables of similar international products.

Because special cables can meet the needs of special environments and special occasions, coupled with the ability to produce special cables that require strong self-equipment, and the threshold is relatively high, special cables will become the "darlings" of the future market. Each capable cable company will rise." Fight for pet."

Third, high-voltage, ultra-high voltage UHV cable is a variety of special cable, the reason why it is introduced separately, because UHV cable in the future market demand, can be described as "outstanding", UHV construction will rise to the country The height of the strategy has brought a huge ripple to the cable production industry, and the demand for UHV cable will be strong.

Therefore, in terms of products, due to the economic development and urban construction, the demand for medium and low-voltage power cable products will gradually decrease. In order to achieve the goal of opening up the market, enterprises should reduce the investment in low-voltage power cables. In the future, the market will be the rapid growth of high-voltage and ultra-high voltage power cables. High-voltage and ultra-high voltage power cables are the market trend. Therefore, companies should strengthen the research and development of high-voltage and ultra-high-pressure technology and increase the overall added value of power cables.

Fourth, the refinement of the so-called product refinement, the use of more refined raw materials, use less raw materials but can have more powerful performance. For instance, the skeleton fiber-optic cable with special information research and development can be laid through pipelines and overhead lines. The cable diameter is small, the weight is light, and the lateral pressure resistance performance is good. The fiber can be laid at any time in the middle, and the construction and installation are convenient; the optical fiber density is high. (Small size); dry structure, no grease pollution, can use color bar identification.

In foreign countries, the research team composed of Australian and American scientists has successfully designed the world's finest nanowires. The thickness is only one ten thousandth of that of human hair, but the conductivity is comparable to traditional copper wires.
