电力大发展 为高压开关行业带来广阔市场

高压开关设备在电网中起控制和保护作用。电网的大发展．为高压开关行业提供了极好的发展空间。本文介绍了我国高压开关行业取得的业绩、龙头企业、热点产品等，以及在中压领域掀起的合资并购风和形成产品链的动向．电力在发展对高压开关的需要以及高压断路器在电网的运行经验和试品试验情况分析。

The rapid and stable growth of high-voltage switch industry is mainly because the great development of power has brought an extremely good development opportunity for high-voltage switches. Additionally, the power sector favors GIS, H-GIS and C-GIS, because these products are of high technology with unique advantages that can reduce the use of land, avoid any external impact and raise the reliability and safety of operation. Especially in such economically developed regions as Shanghai, Jiangsu and Zhejiang, these products have become the first option. For instance, in Jiangsu, from the second half of 2003 to the mid of 2004, the new 252 kV GIS had 50 intervals and 126 kV GIS had 317 intervals. In Shanghai, 110 kV and 220 kV substations will be mainly GIS in the future.
