Wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion.In the broad sense, wires and cables are also referred to as cables, while in the narrow sense, cables refer to insulated cables.It can be defined as an aggregate composed of the following parts: one or more insulated wire cores, as well as their respective possible coating, total protective layer and outer protective layer, and cables can also have additional uninsulated conductors.
The main features of this kind of products are: pure conductor metal, without insulation and sheath layer, such as aluminum conductor steel wire, copper aluminum bus bar, electric locomotive line, etc;The processing technology is mainly pressure processing, such as smelting, calendering, drawing, stranding/compression stranding, etc;The products are mainly used in suburban areas, rural areas, user main lines, switchgear, etc.
[Building Materials Network] At the CCTV 3.15 party, non-standard cable chaos was exposed."If the price is not marked with a non-standard price, the price in the national standard is the price in the national standard." "The '60% discount' is 60% of the national standard, which is called 'discount line' in the industry." "The national standard of 100 meters is more than 500 yuan, and the price of 60% discount is more than 300 yuan." "According to the national standard, this cable should contain 32 copper wires, but the manufacturer only put
[Building Materials Network] In today's offline market, non-standard, branded, fake and inferior wire and cable products are rampant, and the price of wires of the same specification and model is very different.Cheap is not good, good is not cheap.Faced with a variety of wire and cable brands, decoration owners often worry about which channels to buy high-quality and inexpensive home wiring?In recent years, the production capacity of China's wire and cable industry is serious
[Building Materials Network] The development of the wire and cable industry is inseparable from the support of the state. As the wire and cable industry is an important supporting industry of the national economy, the development of all industries can not be separated from wire and cable products. At present, power, communication, chemicals, new energy, rail transit, and urban construction are the large downstream markets of the wire and cable industry,The development of these industries has a great impact on electricity
[Building Materials Network] In February 2013, Shanghai Refrigeration and Air Conditioning Industry Association, Shanghai Aluminum Industry Association and Shanghai University of Technology jointly launched the cooperation project of "replacing copper with aluminum" for 100000 fan coil units, aiming to accelerate the implementation of "replacing copper with aluminum" in the air conditioning field.Copper price is expected to gradually stabilize in the range of 55000~56000 yuan/ton in the middle and late March
[Building Materials Network] How to deal with the sharp fluctuations in the prices of raw materials in the wire and cable industry?In the face of frequent fluctuations in the prices of copper, aluminum and other raw materials in the market, wire and cable enterprises should adhere to the principle of production based on sales, do a good job in "locking" and keep the pulse of the market.Lock the price of copper and aluminum with the sales price, and reverse the cost of production and manufacturing with the sales price, so as to ensure profitability and avoid the price of copper and aluminum
[Building Materials Network] At present, the price of copper and aluminum, the main raw materials of wires and cables, is always in a high shock, which brings many difficulties to the production and operation of wire and cable enterprises.How to better control the cost within the ideal range has become a concern of many enterprises.In the face of frequent fluctuations in the prices of copper, aluminum and other raw materials in the market, wire and cable enterprises should adhere to the principle of fixed production based on sales“
[Building materials network] In addition to copper, aluminum is the raw material that is widely used in the cable industry.In the process of national economic development, industrialization and urbanization will inevitably generate a huge demand for power cables.According to the statistics of Shanghai Cable Research Institute and the Wire and Cable Branch of China Electrical Appliance Industry Association, the output of aluminum conductors in the wire and cable industry in 2009 was about 2 million tons.Since this year,
High density polyethylene (HDPE) is a kind of thermoplastic resin with high crystallinity and non polarity.The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section.PE has excellent resistance to most domestic and industrial chemicals.Some kinds of chemicals can cause chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogens
[Building Materials Network] The wire and cable industry is the second largest industry in China after the automobile industry. In recent years, copper consumption accounts for 60% - 86% of the total domestic copper consumption. The development of the wire and cable industry directly affects the demand for refined copper in China, and ultimately affects the price trend of copper.Therefore, understand the development status and characteristics of China's wire and cable industry, and analyze its future development trend
