<P>PROBLEM TO BE SOLVED: To prevent deformation of a device column and a damage on a device side face due to external vibration caused by transport of an arrester and an earthquake. <P>SOLUTION: An insulation support column 4 is provided in a position where the support column does not interfere with an outer periphery of an element 2 laminated in each lamination element column 1. In addition, a connection insulating plate 50 connects between each lamination element column 1 as well as between the lamination element column 1 and the insulation support column 4, improving mechanical strength. Furthermore, even when external vibration is applied, the insulation support column 4 and the element 2 do not directly contact each other, preventing a damage on the element 2, therefore stability of the arrester performance is improved. <P>COPYRIGHT: (C)2012,JPO&INPIT |
