Can the iron chimney be grounded directly without installing the lightning rod?
First of all, regardless of whether the installation of lightning rod should be grounded.Your question is as long as the installation of lightning rod can "avoid" lightning arrester, too, also called the "lightning rod", the ground is not good, it is burned.If lightning is not installed in the iron chimney, because iron is because it itself is a lightning rod, the rod tightly you don't habit (only in this case), the premise is must be properly grounded.
Many people do not agree that the iron chimney is the concept of lightning rod, it is necessary to weld a sharp metal rod is the lightning rod. A pointed stick lightning because we used the principle of tip discharge, because of its discharge, so the discharge than other objects earlier, this is the industry often say "pilot", because of his first conductive effect, so as to play the role of protecting other buildings.
As a chimney of iron, there must be many sharp edges and corners as long as it is not made deliberately. Secondly, the most important thing is to highlight the ground ground, the excellent iron pipe itself is a good discharge terminal.Therefore, in theory, the iron chimney is not connected with the lightning rod directly to ground directly. But there is no special pardon. Just watch it
