Why is the roof only used as a lightning conductor? Not a lightning rod?
The lightning belt was formerly known as the lightning protection design code for buildings, which has been abandoned in the latest edition of the GB50057-2010 code for lightning protection design. If the lightning belt is suspended, it is called a lightning line; if the line is laid in mesh, it is called a flash network. In short, eventually, is a type of lightning arrester, calculation of the scope of protection of buildings, should be carried out according to the principle of the rolling ball method.
Lightning belts, like lightning arresters, belong to the type of lightning arrester. The difference is that the lightning rod is vertically upward, only at the root and the down lead is connected, is generally a Ming lightning belt; is generally horizontal or inclined laying (according to the inclination of the roof may be), there are at least two places (pendulous connected and shieldingdownconductors), is generally Ming set, but can also be deposited in the dark below roof tile or concrete.
Roof with lightning protection area of lightning is bigger, more effective, but also can effectively prevent thunder.
