Low resistance grounding module HD-DJ

This product has the characteristics of low resistivity, no toxicity, no rot, no pollution, easy installation and long service life.it can be used to prevent direct lightning strikes, lightning protection induction mines, AC/DC work sites, and safety grounds. Applicable to a variety of soil resistivity areas, has a more significant effect on high soil resistivity areas. The main components of the grounding module are: the main conductor is composed of several kinds of conductive materials plus mixed strong electrolyte, and the metal pole core is connected with the drain device in the module to make the ground current discharge to the earth quickly.

The grounding modules can be buried vertically or horizontally with the depth not less than 0.8 meter, and can be appropriately buried deeply for the earth layer of high resistivity. The distance between the modules shall be not less than 2.5 meters when several modules are buried in parallel.

When the module is connected with the module pole piece or the ground wires, the bonding bars must be adopted for connection. If each connection point is needed to be buried, the connection point must be welded, the welding contact surface not less than 6D or a layer of anticorrosive paint is coated on each connection point to prevent the corrosion of the pole pieces after each connection point (welding point) is removed the surplus surface.

The grounding modules shall be tamped in layers in backfill; and the resistance value of the grounding resistor is measured after the grounding modules are buried for three to five days.
