PROBLEM TO BE SOLVED: To enable excellent insulating resistance characteristics and heat radiation properties, higher safety in burning, and size and weight saving by joining one end of a zinc oxide element to a high voltage electrode, and the other end of the zinc oxide element to a ground electrode by a bonding agent, and linearly connecting them. SOLUTION: A high voltage electrode 2 is physically and chemically joined to one end of a non-linear resistance element 1 by a bonding agent 4, similarly a ground electrode 3 is joined to the other end of the non-linear resistance element 1 by the bonding agent 4, and the non-linear resistance element 1, the high voltage electrode 2 and the ground electrode 3 are linearly connected. For connection of the high voltage electrode 2 and a high voltage lead wire 5, a detachable connector of a male connector and a female connector is used which can work with spring-action. The non-linear resistance element 1 bas 250 to 600 V/mm action initiating voltage per unit length. |
