The equipment protection device markets offer countless varistor compositions. But, all the compositions are based in high cost materials

The compositions based in oxide calcium mixed (CCTO) provides the development of safety devices against power surge with inferior costs in relation to the competitors currently in the market, such as the zinc oxide (ZnO), based in silicon carbide (SiC) or based in titanites. Present a alternative and efficient economic for equipment protection in the high tension nets, like those used in the generation and distribution sector of electric energy.
