Abstract (en)
An arrestor provides a bushing (2) installed in an opened section (1a) of an equipment case (1) hermetically, and a molded arrestor elements stack (6) of this invention is installed in the bushing (2) removably. The bushing (2) provides a rigid, insulated bushing body (3) and a high-voltage shielding electrode (4) embedded in the tip of the bushing body (3) concentrically with the bushing body (3). The bushing body (3) provides an intermediate cylindrical section (53) having a tapered insertion hole (53a) and the high-voltage shielding electrode (4) provides a shielding body (41). The molded arrestor elements stack (6) provides an arrestor elements stack (61) comprising a layer stack of a plurality of arrestor elements (61a) containing zinc oxide as the main component, and a molded rubber (67) comprising silicone rubber and so on is provided at the circumference of the arrestor elements stack (61).
