China's power sector in the application of aluminum alloy on the transmission line hardware instead of the traditional hardware ferromagnetic materials, has obtained the remarkable energy-saving effect, and improve the working efficiency, reduces the maintenance outage time. Jingzhou, hubei province electricity use with the 12000 strain clamp and energy saving, power saving 1.43 million kilowatt-hours per year, saving electricity expenses 572000 yuan.

At present our country power lines with the use of electricity is basically can cast iron satin of ferromagnetic materials, in the hardware will produce magnetic hysteresis loss and eddy current loss. Survey statistics show that the distribution of loss produced by common hardware of transmission capacity of 0. 01% to 0. 03%. Made of aluminum alloy energy-saving hardware to eliminate hysteresis losses, eddy current loss is greatly reduced. In addition, with the energy saving in structure from the traditional type bolt structure to wedge structure, raise the working efficiency, reduce the construction cost.

The information provided according to the state economic and trade commission energy conservation information dissemination center, with the energy conservation has been developed for each of the transmission line voltage grade series products and put into use, its mechanical performance and life are higher than that of ordinary cast iron fittings, can be widely used in transport, distribution circuit construction and transformation, market potential is very great. Our distribution line length is about 20 million kilometers, according to the 10 group (30) per km line installation hardware calculation, its market potential of 600 million only. Such as 10% of the ferromagnetic materials hardware is replaced by energy-saving hardware, festival capacity of up to 6 billion KWH.
