High-grade metal doors and windows ground
It is a very important measure to reduce the occurrence of fire, explosion, life hazard and equipotential in the space where lightning protection is needed. The equipotential is connected by means of a connecting wire or an overvoltage protector to the lightning protection device in the space requiring lightning protection, the metal frame of the building, the metal device, the outer conductor, the electrical and the telecommunication device. High-rise buildings must be reinforced concrete structure, steel structure of the building, should make full use of its metal parts to do lightning protection device, the metal as much as possible as a whole. Reinforced concrete components and steel structures in the steel should be connected to each other, the components must be connected between the electrical path, so that the entire building in the pressure. So the metal curtain wall, aluminum alloy doors and windows design should be fully aware of the building's lightning protection devices and curtain walls, doors and windows

Therefore, metal curtain wall, aluminum alloy doors and windows design should be fully aware of the building's lightning protection devices and curtain walls, doors and windows of the lightning protection device outlet, and then determine a reasonable, economical, safe curtain wall, windows and doors mine design.
Metal curtain wall, aluminum alloy doors and windows frame and other large metal objects, if the distance from the ground is equal to the ball radius and above, it should be connected with the lightning protection device, which is the first anti-side strike should take preventive measures. (The so-called ball radius is a sphere with a radius of Hr to scroll along the need to prevent lightning parts, when the ball only touched the flash device, or only touch the flash device and the ground without touching the need to protect the site, then the location To get the protection of the flash device).
