The power industry has long been China's pillar industry and occupies an important position in the national economy. With the rapid development of China's economy since the 1990s, the wire and cable manufacturing industry has also grown vigorously as an important part of the power industry's industrial chain. In particular, in recent years, China's economic development has faced bottlenecks in energy and electricity. As the country continues to increase investment in electricity, the industry has entered a period of rapid development.
China's power industry has a long-term phenomenon of "heavy power supply and light grid". The ratio between power supply and power grid is 7:3, and the ratio in developed countries is basically 5:5. Consequently, the bottleneck of power transmission and transformation is power. Supply constraints, this will inevitably bring good opportunities for development in power grid construction.
The power transmission and transformation primary equipment industry of the power cable manufacturing industry has a relatively low technological content, low barriers to entry, and the user is mainly the State Grid Corporation. This market pattern results in the partial loss of pricing power of many equipment suppliers and the rapid development of the entire industry. After the expansion, it faces the problem of high raw material prices. Competition in the industry has become increasingly fierce, and profits have shown a downward trend. The secondary power transmission equipment industry is an industry with relatively small cyclical fluctuations. It involves high-tech fields and has high technical barriers. Big company monopoly. In view of the prospects for the development of China's power industry, the wire and cable manufacturing industry as its sub-sector continues to have better room for development under the promotion of the environment.
From the perspective of the development of the power cable industry, the development of power cables in the next few years will mainly show the following trends:
(1) Although low-voltage power cables of 1KV and below are still mainly based on PVC cables, the trend of gradual replacement of PVC cables by low-voltage cross-linked cables will be strengthened, and the application of warm water cross-linked cables will increase. Low-smoke halogen-free flame-retardant cables will develop.
(2) The 6-35KV medium voltage power cable is still dominated by cross-linked cables, and prefabricated cable accessories are more widely used.
(3) The application of 110-220KV cross-linked cable will exceed the oil-filled cable, and it is necessary to improve the complete supply capacity of accessories. The domestic application of oil-filled cables is reduced, and the number of oil-filled cable exports should be increased. Stainless steel electrode (4) superconducting cable research should start. The basic structure, process production, performance testing and superconducting connections were studied to produce samples.
Wire and cable are widely used in energy, transportation, information and communication, construction, railways, urban rail, automobile, aviation, metallurgy, petrochemical and many other industries. At present, China's wire and cable industry is at a new stage of development, with the future In the past few years, with the development of urbanization and heavy industrialization in China, the demand for wires and cables in the fields of communication networks, power grid construction, transportation, etc. is still growing rapidly.
At present, there are more than 6,000 enterprises in the country's wire and cable industry. The industry concentration is very low. There are many enterprises that are “small and all†and “intermediateâ€. The economy of scale is poor. Therefore, the domestic wire and cable industry is highly competitive in low-end products. .
However, in the emphasis on safety and high-grade wire and cable products for environmental protection (such as low smoke, halogen-free, fire-retardant, flame-retardant cables, etc.), the added value of products is high, and the gross profit of the products is as high as 40%. Due to lack of capacity, China needs a lot of imports to meet demand. This has provided a broad space for development for domestic wire and cable manufacturing companies that possess core technologies and master special cable product production capabilities.

UFO High Bay light, due to the unique shape, beautiful like UFO (UFO) and named. The use of high-precision fully automated equipment, a forming aluminum fins heat dissipation shell, good heat dissipation, the use of multi-chip high-power high-performance high light refers to the 3030LED lamp beads, light uniform, with Taiwan Mingwei circular power; , Effectively prevent the ambient temperature difference caused by fog, waterproof and dustproof performance. Long life, light fades small, can be widely used in outdoor and indoor harsh application environment.
As a new type of mining lamp, it uses the lens with light design, do not need to increase the reflector with additional light, so there is no traditional LED mining lamp in the transport process is easy to deformation of the reflector phenomenon, and transportation costs are relatively lower.
