First, special overhead lines

Although the special overhead line with special requirements can be produced in China, there is still a big gap between the technical performance of high heat resistance, high corrosion resistance, creep resistance, softness and high conductivity compared with the advanced level in foreign countries. Another example is the split overhead line, which has gaps in technical performance indicators such as corrosion resistance, vibration resistance, snow and ice resistance, low corona loss, low arc loss, low arc volume, and double capacity. In order to meet the needs of major projects such as the Three Gorges, special overhead lines need to be developed and improved in terms of product variety and product performance.

Second, nuclear power plant wire and cable

Nuclear power plant cables are distributed in nuclear islands, conventional islands and BOP parts of nuclear stations for power transmission, control, computers, instruments, etc. The types of cables required for a nuclear station are basically the same as those of thermal power stations. However, due to the strict technical requirements for halogen-free, low-smoke and low-toxicity of nuclear power plant cables, China can only produce wire and cable for the periphery of nuclear islands. Most of the rest can only rely on imports.

According to the National Energy Development 12th Five-Year Plan and the Emerging Energy Industry Development Plan, if the non-petrochemical energy ratio reaches 15% in 2020, China's nuclear power scale will reach at least 75 million kilowatts. At present, the installed capacity of nuclear power in China is only 9 million kilowatts, and there will be 7 to 8 times the growth space in the future.

Therefore, cables for nuclear power plants have good market prospects.

Third, low-smoke low-halogen, low-smoke halogen-free flame-retardant wire and cable

This product is mainly used in some important places such as subways, tunnels, oil platforms, ships, power stations, etc. The above-mentioned related industries are in a state of rapid development during the “Twelfth Five-Year Plan” period, such as the construction and improvement of domestic subways and the comprehensive construction of railway networks. (including the high-speed rail network), this will further stimulate the demand for high-performance environmentally friendly low-smoke low-halogen and low-smoke halogen-free cable products.

Fourth, automotive wiring

During the "Twelfth Five-Year Plan" period, China's auto industry will continue to develop rapidly. In 2015, the annual production of automobiles reached 25 million units, compared with 16 million units during the “11th Five-Year Plan” period, with an expected increase of 56%. Therefore, the demand for automotive wiring will also increase significantly. The future development trend of this product is high temperature, high damping, thin wall and shielded automotive wiring.

Five, high flame retardant wire and cable

At present, most of the domestically produced flame-retardant cables are C-class and B-class, and the high-flame-retardant category A is still in development, which is still far from the requirements of many high-quality engineering projects in China. During the five-year period, the development direction is to achieve a variety of A-class flame retardant and a variety of cables to meet a variety of requirements for high flame-retardant performance applications.

6. Broadband and local network cables for intelligent buildings (6A, 7 and 8 digital network communication wires and cables)

The product also has a variety of signal functions such as transmission telephone, fax, videophone, burglar alarm, etc., also known as data cable. This product has accounted for more than 20% of all insulated cables in the United States. With the rapid development of smart buildings, computer industrialization and information highway engineering in China, the demand for this cable will also increase. At present, the transmission rate of the cable has reached 250MHz (ie, Category 6 cable), and it is expected to reach a transmission frequency of 800MHz during the "Twelfth Five-Year Plan" period, which can meet the demand for "three networks in one" 1) transmission medium.
