<p>PROBLEM TO BE SOLVED: To ensure the soundness of a lightning suppression type lightning arrester for the lightning, by ensuring the mechanical strength and thermal shock strength, while ensuring insulation performance of a cylindrical insulator coupling the upper and lower electrode bodies.SOLUTION: A lightning arrester includes a lightning pole member 1 having an insulator 13 insulating an upper electrode body 11 and a lower electrode body 12, and a support member 3 provided below the lightning pole member. The insulator has a cylindrical insulator 14 arranged between the upper electrode body and lower electrode body, and a cover member 15 arranged around the cylindrical insulator, and the cylindrical insulator is formed of fine ceramic.</p> |
