China is in urgent need of electrical power. Huge power plants are built all over the country and the enormous flow of electrical power to the large megacities has to
cross several thousand kilometers from the source to the end user.
At those dimensions, losses of the power lines can be significant. The State Grid Corporation of China (SGCC) is thus aiming for 1,100 kV as the voltage level for AC transmission to keep losses as low as possible, a step into a new area of electrical grids.
ABB, together with its partners and suppliers, has developed the heart of such a system – a gas-insulated switchgear design – that could pass all the tests with this groundbreaking technology.

ABB’s current breaker portfolio includes breakers with rated nominal currents ranging from 6300 A to over 50,000 A. HECS breakers are designed for nominal currents up to 18,000 A. However, a side effect of these large currents is heat dissipation in the device, which must be limited if other system components are to remain within their rated temperature tolerances. Natural cooling limits the rated
nominal current and therefore many of today’s GCBs employ forced cooling methods to increase nominal current levels. However, these “forced” coolers also limit nominal current capability.
To increase GCB nominal currents, an innovative cooling method was required to meet the ever-increasing demand for lighter, cheaper and more powerful devices. Using socalled heat pipes to achieve efficient heat transfer, not only have they developed two products that are lighter and more robust than previous versions, but GCB performance has increased by over 25 percent!

Generator circuit-breakers are the ‘big boys’ of the breaker world; they have to be. A fault of up to 200 kA
somewhere in the field is bad enough, but close to a generator it can lead to an event of literally seismic
proportions – the fault current can be of such a magnitude that the induced magnetic forces cause solid steel shafts to bend and crash.
ABB HEC 7/8 SF6 breakers are designed for this demanding task. They can handle anything even the world’s biggest power stations can throw at them. But just how do you break such a huge current so close to the generator? And how can the breaker effectively deal with the arc that is produced?
