With the uprising movement of Chinese railways and progress of electric railroad, the small tonnage full hydraulic railway crane becomes more urgently needed for development with characteristics of fast speed self-propelled running and high speed in train formation, hence, the high level requirement is resulted in terms of train formation and self-propelled running speed of railway crane. For 20t universal railway crane, features such as running with the load and weight lifting due to high hauling capacity are required besides hook lifting, bucket grabbing and magnetic panel lifting.

随着我国铁路事业的不断壮大，电气化铁路的发展，开发小吨位的自力走行速度快、回送速度高，能满足电气化线路的立杆作业的全液压铁路起重机迫在眉睫，对铁路起重机的回送和自力走行速度有了更高的要求。20t多功能铁路起重机，即具有吊钩、抓斗、磁盘吊3种功能外，还具有一定带载走行以及因牵引能力大也可作为吊车机使用。

With building and operating of several high voltage DC electric transmission lines in China, it is very important for providing domestic high voltage DC metal oxide arresters applied in HVDC system.

随着中国多条高压直流输电线路的建成和运营，直流输电系统用高压直流金属氧化物避雷器的国产化具有重要的意义。

To complete the 220 kV line design and below the total length of over 3,000 km (including re-ice line about 300 km), 220 kV substation and the total capacity of 1.2 million kVA which Wushan Chengguan 110 (35) kV substation project, Yue Fu Chi-Beach - Chengguan 110 kV lines and other projects designed by the application of the technology industry in Sichuan Hydropower 1998 Good Design Award. 1995 commitment to "small rural electrification in Sichuan Province typical design of the substation" assessment by experts. 2000 commitment to the "small rural power grids of the typical design of unmanned substation", the expert assessment by the province and issued.

In 1992, a three phase double circuit line between Goudey and Oakdale station was reconstructed to six-phase line and was operated commercially by New York state electric and gas. It is a milestone from theoretical research to practical application in the development of six-phase transmission.With the decrease of cultivated land and the environmental problem in china, it is an important factor to improve power transmission density in the construction of electric network, and the predominance of six-phase transmission is obvious in this aspect.

六相输电是多相输电的一种，在国外六相输电技术作为提高输电线路功率传输密度，节约线路走廊空间的重要手段得到了充分的重视，对六相输电技术的研究也取得了很大的进展。1992年，美国纽约电力和天然气公司将Goudey到Oakdale之间的一条双回线路改造成了六相输电线，并且已经投入了商业运行，这标志着多相输电技术已经从理论研究向实际应用迈出了重要的一步。
