Introduction to lightning protection tower

The lightning protection (rod) tower products are produced according to the tower shape and technical standards in the "Installation of Lightning Protection Facilities for Buildings" published by the China Building Standards Design and Research Institute. The tower shape is selected from the national standard catalog 99D501-1 or D562.

The main products are:Steel reinforced tower (GJT series), four column angle steel tower (GFL series), ring

Products such as shaped steel tube lightning rods (CH series), reinforced concrete ring pole lightning rods (ZG series), and lightning protection towers (GFW series).advantage:

Using round steel or angle steel as the tower column material, the wind load coefficient is small and the wind resistance is strong. The tower column is connected by external flanges or angle steel wrapped with iron, and the bolts are under tension, which is not easy to damage and reduces maintenance costs. The tower column is arranged in a regular triangle or square shape, which saves steel, has a small follow-up area, occupies a small land area, saves land resources, is conveniently located, has a light weight, is easy to transport and install, has a short construction period, is designed with wind load curve changes, smooth lines, mature technology, and is not easy to collapse in rare wind conditions. The structure is safe and reliable.Design wind speed:

32 meters per second.Seismic cracking degree:

8 degrees.Lightning protection principle:

A lightning current arrester is a non inductive, low impedance metal inner conductor down conductor that delivers the lightning current after flashover to the ground and prevents the protected antenna tower or building from side impact and electrification. In most cases, the impact of static electric field cables is less than 1/10 of the impedance of the iron tower, avoiding the electrification of buildings or iron towers and eliminating lightning strikes; Limit the current intensity of landmines to reduce the harm of counterattacks and induced overvoltages to the protected equipment; The protection range is calculated according to the rolling ball method in accordance with the national standard GB50057.Height:

More than 10 meters.Design weight:

Determine according to the national standard map (the specific weight depends on the region, with slight differences between areas with few and strong mines, coastal wetlands, and western arid regions).Material:

Q235-Q345 round steel/angle steel.Anti corrosion treatment:

Hot dip galvanizing.Material origin:

Baosteel/Shougang/Handan Iron and Steel/Tangshan Iron and Steel, etc.Validity period:

More than 30 years.Applicable Unit
