  • Polymer surge arrester
    Patent number: 8982526
    Abstract: A plurality of insulating rods are placed at peripheries of the nonlinear resistor and the metal plates, and each having an upper end portion and a lower end portion inserted into holes formed in the electrodes. A spacer is placed between an inner peripheral surface of the hole and an outer peripheral surface of the insulating rod inside the hole of the electrode, and a fixing screw is attached to the hole of the electrode. A double-ended bolt couples the metal plate and the electrode together. The double-ended bolt has a first screw part and a second screw part opposite in a fastening direction to the first screw part which are provided on a same axis. The first screw part is attached to the metal plate, and the second screw part is attached to the electrode.

  • Polymer surge arrester
    Patent number: 8243413
    Abstract: 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.
