Strict environmental protection is conducive to aluminum promotion

1. Huge aluminum processing capacity.
From 2006 to 2016, the accumulated investment in fixed assets of nonferrous metal alloy manufacturing and calendering industry exceeded 2201.4 billion yuan, with an average annual growth rate of 26.97%, of which the proportion of aluminum processing investment basically remained above 45%. A large amount of investment has led to the rapid growth of production capacity (at present, China’s aluminum extrusion production capacity accounts for 76% of the world’s total production capacity; the casting hot rolling production capacity accounts for about 59% of the world’s total production capacity; and the twin roll continuous casting and rolling strip production capacity accounts for about 67.5% of the world’s total production capacity). The export volume of aluminium sheet, aluminum foil and aluminum strip also ranks among the top in the world, with the largest number of world-class equipment.

At present, China has the world’s largest and full range of aluminum surface treatment production lines, the largest number of Sigmak heavy extruders, CVC cold rolling mills, the largest number of Ashenbach aluminum foil mills, and the largest number of hot and cold continuous rolling mills. However, how to make full use of these advanced equipment and play their due role will test the creativity, imagination and ability of industry personnel. Otherwise, it will add a heavy burden.

2. Homogeneous price competition is becoming increasingly fierce.
A lot of investment is focused on high-end aluminum strip and large extrusion products, resulting in structural overcapacity. The more high-end products, the more excess. As a result, product homogeneity competition and price war become increasingly fierce. This phenomenon is widespread from low-end products to high-end products. For example, in recent years, due to homogeneous competition, the processing cost of some products with high added value has become lower and lower. For example, the processing cost of CTP printed board base has dropped from 12000 yuan/ton to 3800 yuan/ton; The processing cost of aluminum alloy can materials has decreased from the original 20000 yuan/ton to less than 4000 yuan/ton; The processing cost of aluminum alloy profiles for high-speed railway carriages has decreased from 50000-70000 yuan/ton to 10000-15000 yuan/ton.

3. There is a good policy environment for the development of aluminum processing.
The Made in China 2025 issued in 2015 and the 13th Five Year Development Plan for Nonferrous Metals Industry to be released clearly propose to accelerate the development of high-performance light alloy materials. As the most important lightweight, energy-saving, renewable and environment-friendly material, aluminum alloy is the first choice in aviation, automobile, construction, electronics and packaging industries.

The General Office of the State Council recently released the Guiding Opinions on Creating a Good Market Environment, Promoting the Restructuring of the Non ferrous Metals Industry, Promoting Transformation and Increasing Benefits, which also clearly proposed to further increase the consumption of non-ferrous materials in aviation, automotive, construction, electronics, packaging and other fields, and focus on the development of aluminum alloy plates for passenger vehicles, aviation and marine use.

Therefore, with the deepening of supply side structural reform, the business environment for the development of China’s aluminum processing industry will be improved.

The Ministry of Industry and Information Technology said that while supporting the expansion of aluminum consumption in traditional areas, it would continue to implement major special projects such as technological transformation, foundation strengthening projects and new materials closely related to the aluminum processing industry, and would also increase targeted and continuous support for key areas such as aviation aluminum materials and car panels. The Ministry of Industry and Information Technology has also successively introduced some specific policies and measures to support the expansion of aluminum application in recent years. For example, at present, aluminum alloy semi trailers and tank cars can enjoy the policies of energy conservation and emission reduction in transportation, recommended models for highway drop and hook transportation, vehicle and vessel tax reduction and exemption. Aluminum alloy heat insulation profiles, color aluminum plates, aluminum alloy building templates, etc. are listed as green building materials.

Medium and low voltage cable accessories are currently used more products

The main types of products that are currently used for medium and low voltage cable accessories are heat shrinkable accessories, prefabricated accessories, and cold shrinkable accessories. They have the following characteristics:

1. Heat shrinkable accessories

The material used is generally a blend of polyethylene, ethylene-vinyl acetate (EVA), and ethylene-propylene rubber. This kind of product mainly uses stress tube to deal with the problem of electric stress concentration. That is, the parameter control method is used to relieve the electric field stress concentration. The main advantages are light weight, easy installation, good performance and low price.

The stress tube is a kind of heat-shrinkable tube with special electrical parameters with moderate volume resistivity (1010-1012Ωcm) and large dielectric constant (20-25). The electrical parameters are used to force the stress at the abc cable insulation and shielding fracture to evacuate. The stress tubes are more evenly distributed. This technology is generally used in cable accessories of 35kV and below. Because the stress tube will heat up when the voltage level is high and cannot work reliably.

The key technical issues in its use are:

To ensure that the electrical parameters of the stress tube must reach the values ​​specified in the above-mentioned standards, it can work reliably. In addition, attention should be paid to filling the air gap at the fracture of the cable insulation semi-conductive layer with silicone grease to eliminate gas and achieve the purpose of reducing partial discharge. Cross-linked cables will shrink greatly during operation due to poor internal stress handling, so when installing accessories, pay attention to the stress tube and the insulation shield to cover not less than 20mm to prevent the stress tube from separating from the insulation shield during shrinkage. Due to the small elasticity of heat-shrinkable accessories, air gaps may occur at the interface during thermal expansion and contraction during operation. Therefore, the sealing technology is very important to prevent moisture intrusion.

2. Prefabricated accessories

The material used is generally silicone rubber or ethylene propylene rubber. The geometric structure method is mainly used to deal with the stress concentration problem. Its main advantages are excellent material performance, easier and faster installation, installation without heating, good flexibility, and greatly improved interface performance. It is the main form adopted by low-voltage and high-voltage cables in recent years. The disadvantage lies in the high requirements for the outer diameter of the cable insulation layer. The usual interference is 2-5mm (that is, the outer diameter of the cable insulation is larger than the inner hole diameter of the cable accessory by 2-5mm). The interference is too small, and the cable The accessories will malfunction; the interference is too large, and the installation of the cable accessories is very difficult (high process requirements). Especially in the middle joint, the problem is prominent, the installation is not convenient, and it often becomes the point of failure. In addition, the price is more expensive.

The key technical issues in its use are:

The size of the accessory and the size of the cable to be installed must meet the specified requirements. In addition, it is necessary to use silicone grease to lubricate the interface to facilitate installation and fill the air gap of the interface. Prefabricated accessories generally rely on their own rubber elasticity to have a certain sealing effect, and sometimes sealants and elastic clamps can be used to enhance the sealing.

3. Cold shrinkable accessories

The material used is generally silicone rubber or ethylene propylene rubber. Cold-shrinkable accessories generally adopt geometric structure method and parameter control method to deal with the problem of electric stress concentration. The geometric structure method that uses the stress cone to relieve the concentrated electric field distribution is better than the product of the parameter control method.

Like prefabricated accessories, it has excellent material properties, can be installed without heating, and has good flexibility, which greatly improves the interface performance. Compared with prefabricated accessories, its advantage is that it is more convenient to install and only needs to be in the correct position. The installation can be completed by pulling out the inner lining core tube of the cable accessory. The material used is better than prefabricated accessories in terms of mechanical strength, and the requirements for the outer diameter of the cable insulation layer are not very high, as long as the inner diameter of the cable accessories is less than the outer diameter of the cable insulation 2mm (the data is like this, this The type attachment requires a deviation of 2~5mm (Editor) to fully meet the requirements. Therefore, the construction and installation of cold shrinkable accessories are more convenient.

Its biggest feature is that the installation process is more convenient and quicker. After the installation is in place, its working performance is the same as the prefabricated accessories.

The price is equivalent to that of prefabricated accessories, and slightly higher than heat shrinkable accessories. It is the most cost-effective product.
