High-voltage cable development shows a growth trend

After experiencing the trend of a slight drop in power investment during the first two years of the “Twelfth Five-Year Plan”, what kind of trend will the investment in high-voltage power cables show?

Large and medium-sized cities have gathered a large number of manufacturing industries. They are also the areas where the hardware carriers of service industries and other service industries have gathered and the highest degree of electrification of residential lives. They are the most important power load centers in China. The increase in urban electricity consumption and the transformation and development of urban power grids are related to the application of high-voltage mining cables. The high-voltage and ultra-high-voltage mining cables are mainly used in the construction of urban power grids. Their application in urban transmission and distribution networks accounts for more than 90% of the total; large-scale industrial and mining enterprises and power stations account for about 10%. Under normal circumstances, the city's annual electricity consumption will reach about 20 million KW. The city network will use 500KV mining cables; the annual electricity consumption will reach 8 million KW, and the city network will use 220KV mining cables.

Whether the investment in power grids can continue to grow in 2013, and through this discovery, this year's grid investment of the two major power grid companies shows a one-one-one-one-one-step drop. It is simple to estimate that in the total power grid investment in 2013, this year's steady growth over the past two years has been possible. determine.

The main direction of this year's high-voltage cable grid investment will be concentrated in the trans-regional transmission grid and urban and rural power grids. The cross-regional power grid is mainly UHV. The urban and rural power grids are mainly promoted by the Party's "eighteenth party" to promote a new type of urbanization construction strategy, grid companies will increase investment in the distribution network and this year's work of the two major power grid companies. Consistent with the plan, the idea of ​​the State Grid this year is that “the development of UHV is the most important thing. Building a distribution network is an important foundation”; China Southern Power Grid pointed out that it is necessary to speed up the construction of the “two-pass” DC project and continue to do a good job of rural networks. Upgrade work.
