Set tup lightning grounding system in Hai Phong

Set up lightning protection systems in Haiphong

A good lightning protection system must be able to receive power from the system lightning lightning collecting needles and release this energy into the ground as quickly as possible, to minimize the possibility of lightning in the energy transmission system damaged devices. The scope of an air terminal and conduct lightning collection system is not fixed but can be seen as a function of the level of power dissipation of the lightning. Therefore the scope of lightning is a statistical quantity.

On the other hand, the scope of lightning is less affected by a system composed collect and conduct lightning, so the arrangement of horizontal and vertical is similar. Therefore do not necessarily have to use sharp or pointed tip-top box, except that it is necessary in terms of practicality.

Earthing systems are integral parts of any public lightning protection systems. It ensures that the resulting surge currents from the protection device to hold earthing ground work and dissipate this energy pulses. Next, play an important role in the lightning, if the lightning protection equipment is not good grounding (earth resistance too high), the lightning into electricity network completely dire consequences can occur. Depending on requirements, and resistive earthing of the building land, we can build a safe earthing system by piling, pile or drill wells drop spindles completely quantities can be calculated.

Set up the grounding system in Hai Phong

A grounding system generally consists of piles of iron or iron poles copper (copper might just be enough) to be buried in the ground. The pile can be used for angle steel or rebar fabrication, conventional length from 1.2 to 1.5 m. The spindles are linked together to form a grounding grid resistor matching requirements of lightning protection works. In many cases, the resistance of grounding grid is too high despite increase the number piles into the ground. In order to achieve the desired ground resistance, in the lightning techniques using chemicals to reduce ground impedance (GEM). To reduce resistance to the earthing system and ensure the stable work of the system, today the link between lightning conductors with ground rods are linked together by means of heat welding (Cad-Weld ) instead of a clamp or brazing as before ...

Earth Resistance chemical reduction (GEM): This is a two-component chemicals being mixed together in water when poured over the area to bury the electrodes would create a glue layer (GEM) uniform. Therefore it is not washed away like ash and salt survive in soil for many years. This compound is particularly appropriate in the midland areas, hills of Vietnam.

JSC commercial construction HKD is the construction and installation of lightning protection systems prestige in the North today. HKD equipped facility, modern equipment and comprehensive, best service for the design, construction, HKD staff there, the professional staff, experienced, enthusiastic and discipline.
