2.Qinghai electric power netting first hung netting to testrunning composite insulator since 1992.From 1994 beginning, it hung netting step by step to testrunning in all Province Ⅲ,Ⅳ grade heavy pollution flashover area (35kV-330kV).
3.The testrunning results show that networks could operate safely except that a few hardware fittings could not meet the demand when conductor allowable temperature is increased from 70 degree Celsius to 80 degree Celsius.
5.13 metro line in Beijing. The localized vehicle and its electric drive system has passed the field type test and running inspection and is under trial operation in No. 13 metro line, in good condition.
