TIME:April 21, 2016        SCAN:

 Converter Valve is the most important equipment of HVDCproject.In the late 70s of the last century,Xi'an XD Power System Co., Ltd. started research and development of thyristor. converter valve and related devices.Which made itself the first company capable of manufacturing and testing of HVDC converter valve in China. Until now, the company has contributed most of the converter valves to all of the domestic HVDC Project.Xi'an XD Power System Co.,Ltd. is nowcaplble of manufacturing and industrialization of both Electric Trig Thyristor (ETT)and Lighting Trig Thyristor(LTT)valves up to±1100kV voltage classes.

       The maximum capacity of HvDc converter valve we have made:

       Rated DC Voftage±1l00kV

       Rated DC Current:5000A
