| titleOfInvention | Zinc oxide varistor, manufacture thereof, and crystallized glass composition for coating |
| abstract | A zinc oxide varistor as a characteristic element of an arrester for protecting transmission or distribution line and the peripheral equipment against lightning surge, being highly reliable, having excellent voltage nonlinearity, discharge withstand current rating characteristic, and charging life characteristic, and having a side high-resistance layer (3) made of a crystallized glass of high crystallinity containing PbO as a main component, and a predetermined amount of SiO2, MoO3, WO3, TiO2, NiO on sides of a sintered body (1). The side layer is intended to enhance the mechanical strength, dielectric strength, voltage nonlinearity, discharge withstand current rating characteristic and charging life characteristic. A crystallized glass composition for coating oxide ceramic such as a zinc oxide varistor, comprising PbO as a main component, ZnO, B2O3, SiO2, and additives including MoO3, WO3, TiO2, and NiO, and having high crystallinity and dielectric strength. |
