ABB has a won a $300m order to supply advanced converter transformers which will be used to transport renewable power to China via long-distance transmission cables from Inner Mongolia.

The Swiss company said today the transformers will feature on two ultra-high-voltage direct current (UHVDC) wires which can connect and deliver up to 10GW.


Hardware will be installed on the 1609km Ximeng-Taizhou and 1231km Shanghaimiao-Shandong 800 kV transmission wires.

ABB said the deal will help China in its goal to use more renewable power.

ABB’s Power Grids division president Claudio Facchin said: “This latest breakthrough of transmitting 10GW of power over a single 800 kV UVDC link underlines ABB’s next level strategy of delivering innovative solutions for the integration of renewables and efficient bulk power transmission to urban centres.” 

He added: “Our ultra-high-voltage technologies are enabling countries like China to transmit ever increasing amounts of power over greater distances, with minimal losses and uncompromising reliability.”
