Specification for installation of lightning arresters for chimneys
This should be installed and tested by a qualified unit. I can't help myself
This is only a rough, specific, you can refer to the relevant specifications, I am also engaged in lightning protection.
First of all, know the height of your chimney. The height of the lightning rod is 1.8 meters and is mounted along the chimney mouth. 40 meters below the chimney can set a lead down line, more than 40 meters, should be set 2 lead line, the spacing can not be more than 30 meters, if it is concrete structure, also can use the main rib as the lead off line. The number of lightning rods is related to the diameter of the chimney, and there are 1-3 branches. More than 100 meters high to set the equalizing ring, from the ground 30 meters, every 12 meters, and is connected with the lead line.
