What Regulations Should the Lightning Protection Tower Be Installed on the Roof?

As a Power accessory supplier, providing Electric Galvanize Bolt, We can see the lightning tower in many high-rise buildings, because it is difficult to install, so we should pay special attention to safety issues and operation skills during installation. First, there will be a layer of zinc on the surface of the lightning protection tower. Be careful not to damage the coating during installation. Secondly, the thickness of the tip of the lightning protection tower should be more than three millimeters. At the same time, the lightning protection tower should be kept vertical and the deviation should be controlled within three thousandths.

Flat steel is twice its width (and at least 3 edges are welded). Round steel is six times its diameter. When the round steel is connected with the flat steel, its length is six times the diameter of the round steel.

The lightning protection tower which are made by Electric Insulating Fitting and others is generally made of round steel or steel pipe, and its diameter should not be less than the following values: the independent lightning protection tower is generally made of 19mm galvanized round steel.

The lightning protection tower on the roof is made of 25mm diameter galvanized steel pipe. The top lightning tower of the water tower adopts galvanized steel pipe with diameter of 25mm or 40mm. The lightning protection tower on the top of the chimney adopts 25mm diameter galvanized round steel or 40mm diameter galvanized steel pipe. The lightning protection ring is made of 12mm diameter galvanized round steel or 100mm2 galvanized flat. Steel, its thickness should be 4mm.

The lightning protection tower should be made of round steel or welded steel pipe. The diameter should not be less than the following values: the needle length is less than 1m: round steel is 12mm, steel pipe is 20mm, needle length is 1-2m: round steel is 16mm, steel pipe is 25mm, chimney The needle on the top: 20mm for round steel and 40mm for steel pipe.
