1. Calculate the cost by the weight of copper. It was effective at the beginning, but the national standard ignored a problem. Your copper is an oxygen-free rod, but the non-standard one is not. When the weight of the scrap copper and the oxygen-free rod are the same, the price of the scrap copper and the oxygen-free rod differ by 10. %. Therefore, the national standard cable has made great efforts to promote it, but it has failed. The difference between the national standard and non-standard guarantees is 10%.

2. Cut corners on accessories. The country has increased resistance inspections, and at the same time increased inspections for conventional products. Non-standard cables have begun to work hard on auxiliary materials. If copper accounts for 70% of the cost of cables, then the cost of auxiliary materials accounts for about 20%. 20% of the cost, if the materials are slightly inferior, the price will be 5% lower than the national standard. You have also seen that many cables that have been exposed recently have problems with accessories.

3. Wire short meter to cable short meter. In fact, the matter of short rice has always existed, and this is the most difficult to investigate. In the past, it often existed on BV, such as 95-meter lines, 98-meter lines, or 90-meter lines. Now because of the increase in inspection items, all products inspected have been included, so non-standard products have begun to work hard in this direction. I hope everyone will pay attention to it. If 100 meters is reduced by 1 meter, 1% of the profit will come out.

4. Thick on both sides and thin in the middle. That is to say, the cables at both ends are national standard, and the middle part is non-standard, so a lot of cost is saved, and the price of the corresponding cable will be much lower. You can't cut the detection cable from the middle, so the leak is drilled like this.

The use of overhead lines will grow significantly

At present, the inter-provincial networking in the north, central and south of China and the gradual realization of the whole country, the large-scale application of ultra-high voltage and large-capacity overhead lines (750KV lines in the northwest, 500KV lines in other areas) will make the overhead lines increase by 10% month-on-month. In addition, the demand for medium-voltage 10-35KV cable products will also increase significantly, or increase at a rate of 8-10% month-on-month. At present, the use of double-ring network power supply in large cities and the increase in the rate of underground cables in downtown areas will greatly increase the use of medium-voltage cables. At present, most urban planning departments have emphasized the power supply of underground cables in urban areas, and some cities have included this requirement in local regulations, which brings great opportunities for medium-voltage distribution cables.

The output value of building wiring will exceed 15%

In recent years, despite the coldness of the real estate industry, the construction industry, as an important industry in the 21st century, will bring opportunities for construction wires and cables for other electrical equipment. Whether it is a residential building, an office building or a shopping mall, a large number of various cable products will be used. At the same time, as consumers' requirements for living conditions continue to increase, the demand for intelligent housing and the construction of various professional networks have brought a huge market for wires and cables. It is estimated that the output value of building wiring will exceed 15% in the wire and cable industry in the future.

The market department of new energy power cables should not be underestimated

With the rapid development of the new energy industry, the market for new energy cable products should not be underestimated. Taking nuclear power as an example, the new energy industry will receive more and more government support in the next few years. Technological progress will make the cost of new energy use continue to drop, and the economic value and social environmental protection benefits will become increasingly prominent. In the past year, the overall trend of the new energy sector has been significantly stronger than that of the Shanghai and Shenzhen stock markets. We are optimistic about the long-term investment value of the new energy sector and maintain the investment rating of "recommended". For example, new energy vehicles, as an important measure to control air pollution in my country, will continue to receive strong support from policies and have good development prospects. At present, the number of charging piles in my country is far from keeping up with the needs of the development of electric vehicles. "Difficulty in charging" is the biggest bottleneck of electric vehicles in my country. Policies to encourage the construction of charging piles will be introduced at an accelerated pace. Tesla's public patents will help the development of the new energy vehicle industry.

Solar PV cable market will also benefit

The solar photovoltaic industry has also attracted the attention of many investors. The development potential of the solar photovoltaic industry is infinite, and it will also inject infinite power into the cable industry. The solar photovoltaic industry is due to China's transformation from a photovoltaic manufacturing country to a photovoltaic installed country. At present, the development of domestic photovoltaic power stations mainly includes ground power stations and distributed photovoltaics. For ground power stations, some industry experts believe that the business model is mature and it is the most beneficial link in the current industrial chain.
