The reason is the general buildings of the electrical design specialized equipment lightning proof system considering more thoughtful, but to the electrical systems do not get much attention, and lightning current general systems by another contractor to be completed.Lightning protection building can contracting much by the sub-contract completing, multiple construction unit crossover operation is compared commonly difficult to coordinate well,there would be a building electrical systems.So strengthening weak lightning become the weak apot,therefore strengthen electrical equipment lightning protection should get much more attention.
