With the "rated voltage 0.6 / 1kV Aluminum conductor XLPE insulated cable" (standard number NB / T42051-2015) on April 2 this year, officially approved, and will be officially implemented on September 1, marking the AAAC conductor industry has officially entered the era of the regular army.
Thus, on "aluminum and copper," topic is once again in the spotlight. People will ask, aluminum and copper market is demonstrated by this national standard be? Copper, aaac conductor industry which will bring far-reaching effects it?
You can see from the scope of this standard, that this standard applies to buildings, structures, and ancillary facilities for power distribution rated voltage 0.6 / 1kv Aluminum conductor XLPE insulated cables. Including fire, smoke, and halogen-free cable.
As the largest supplier of building the real estate industry is a natural choice for industry research. According to real estate research, SMM learned that a large public building, investment accounted for about 10% of electrical engineering total investment, while investment in the electrical cable almost accounted for more than half of the budget, and therefore estimate down to the cable investment demand accounts for about 6% -7% of the total building investment.
Recalling the year 2014, China's real estate development investment amounted to 9.5 trillion yuan, according to the compromise of 6.5% ratio calculation, in 2014 the construction industry cables market size of about 620 billion yuan. It is understood SMM, compared to the mature markets of North America, the standard low-voltage cable corresponding AA8000 series aaac conductor, the current domestic production enterprises have a smaller number of major companies have ZMS AAAC conductor, but production capacity is only 10- 200,000 tons.
Overall, even though, according to incomplete research, known as the country currently capable of producing AAAC conductor companies have more than 100, the domestic aaac conductor manufacturers in different ways, different standards, the introduction of a new subject line of the standardized and unified industry will undoubtedly play the revolutionary impact, but in the short term aluminum wire in full swing in applications is still some way off.
As China Electric Power Research Institute senior engineer consulting professor distribution room Hou Yiming said, "aaac conductor due to its characteristics, can be used in the end user, bridge, coastal and some overhead required special areas, and urban distribution run the most It is important to run security issues, so the copper cable is more suitable. "
In addition, with short-term restricted connection terminals and enterprise technology and market acceptance, aaac conductor is still a relatively slow pace of implementation.
