| Zusammenfassung: | A polymer surge arrester has: internal elements including a plurality of disc-shaped nonlinear resistors disposed in a stacked manner, electrodes disposed at both ends of the nonlinear resistors, and a plurality of insulating rods coupling the electrodes; an insulating outer skin formed outside the internal elements by casting an insulating resin; and disc-shaped porous metal plates interposed between at least parts of the nonlinear resistors. |
