What is the quota for the flat steel used in the lightning belt -40*4?
Set the lightning protection net, the main material is -40*4 galvanized flat steel, if you are using 12 yuan quota steel, also set the lightning protection network quota, but the material is converted into flats on the line,But now the lightning belt is usually 12 yuan steel,
Fixed the lightning belt installation "is based on the 8 mm galvanized steel park system, you can make the material conversion and adjustment.
I have also checked the quota, but there is no flat steel laying in the lightning protection and grounding device of the electrical installation of the second book. I usually refer to the grounding bus.
