<p><P>PROBLEM TO BE SOLVED: To provide a lightning arrester free from loosening of a fixed part between a terminal electrode and an insulation rod. <P>SOLUTION: The lightning arrester includes a laminated voltage nonlinear resistor block, a pair of terminal electrodes 3a, 3b sandwiching the block in the laminated direction, a plurality of insulation rods 4 disposed around a serial element 1b extending in the laminated direction to connect together the pair of terminal electrodes 3a, 3b, a plurality of fasteners coupling together the pair of terminal electrodes 3a, 3b to the insulation rods 4, and silicone rubber 6 functioning as an insulation envelope directly covering the periphery of an inner element 1c including the serial element 1b and the insulation rods 4 to integrate them together. A plurality of insulation rod attaching holes 32 for inserting ends of the insulation rods 4 and fastener attaching holes 33 orthogonal to the insulation rod attaching holes 32 are formed through the pair of terminal electrodes 3a, 3b. Fastener penetrating holes 41 are formed through both ends of the insulation rods 4 to lock the insulation rods 4 by passing the fasteners inserted through the fastener attaching holes 33 through the fastener penetrating holes 41. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
