Introduction to the development history of power cables

The use of power cables has been around for more than a hundred years. 

In 1879, the American inventor T.A. Edison wrapped jute around a copper rod and put it into an iron pipe, and then filled the asphalt mixture to make a cable. 

He laid the cable in New York and created underground power transmission. 

The following year, the British Karende invented the asphalt-impregnated paper-insulated power cable. 

In 1889, the British S.Z. Ferrante laid a 10 kV oil-impregnated paper-insulated cable between London and Dartford. 

In 1908, the UK built a 20 kV cable network. Power cables are getting more and more widely used. 

In 1911, Germany laid a 60 kV high-voltage cable and began the development of high-voltage cables. 

In 1913, the German M. Hoichstedt developed component phase shielded cables, which improved the electric field distribution inside the cable and eliminated the tangential stress of the insulating surface, which became a milestone in the development of power cables. 

In 1952, Sweden laid a 380 kV ultra-high voltage cable in the northern power plant to realize the application of ultra-high voltage cable. 

By the 1980s, 1100 kV and 1200 kV UHV power cables were made.

2012 China Power Cable Industry Depth Research Report is the most professional and comprehensive system depth market research report in the field of power cable.

The report first introduces the background knowledge of power cable, including power cable-related concepts, classification, application, industry chain structure, industry overview, international market dynamics analysis, domestic market dynamics analysis, macroeconomic environment analysis, and economic situation of the power cable industry.

The impact of the power cable industry, national policies, planning analysis, technical parameters of power cable products, production process technology, product cost structure, etc.

Statistics on China's major enterprises' Power Cable capacity, production cost, price, profit, profit margin, etc.
And statistics of 32 enterprises' power cable products customer applications of production capacity market positioning enterprise contact information, etc., and then the relevant data of these enterprises for summary analysis, to obtain China's power cable production market share, production market share, supply and demand, imports and exports and other data statistics.
It also introduces the capacity production price, cost, profit value, profit margin, etc. of Power Cable in China from 2009 to 2013.

Finally, the new Power Cable project opportunities are analyzed through case models.

Risk analysis and investment feasibility analysis. In conclusion, this is an in-depth report dedicated to China's power cable industry.
