Sankosha has developed and manufactured the Ceramic Gas Tube Surge Arrester (Gas Discharge Tube or GDT). Sankosha gas tube arresters protect personnel, equipment and circuitry from abnormally high voltages caused by lightning or electrical transients. Sankosha’s surge protection devices have well defined surge-limiting characteristics enabling them to spark over (or breakdown) when the abnormal voltage on a line reaches a specific level. When sparkover occurs in the GDT, the surge is redirected to earth. Throughout the world, products from Sankosha factories provide protection for equipment and personnel.
