Their most widespread use today is in spark plugs to ignite the fuel in internal combustion engines, but they are also used in lightning arresters and other devices to protect electrical equipment from high-voltage transients.

Further, facilities have been put in place, such as strategically located shelters, lightning arresters and lifebuoys, as well as directional signage and clear markings of no-access areas to keep visitors away from the operation areas.

Among them, the products, like transformers of 750 kV, reactors, lightning arresters, capacitor voltage transformers and isolating switches of 800 kV, have been operated successfully in 750 kV model projects in the northwest; China s first 800 kV double cut-off pot-style breakers has been put into operation at Yinchuan East Substation.
