Earth Rods and Lightning Arresters

The earth rods a small device used to protect all other devices from lightning or similar static currents. It is placing into the ground by connecting to the main electricity source. It has to be placed at least 2 feet distance from the source or building. It can be used as a remover of excess current or current leakage.

Normally we are using lightning arresters to protect our whole devices and building from the sudden excess electricity. By placing the lightning arrester above the building or top of the building, It must be connected with the ground. T do the ground connection it has to be combined with an earthing rod.

In a lightning arrester system, a lightning rod is a single component of the system. To provide a protective function, the lightning rod needs to be connected with the earth. The common thing in all lightning rods is that they are all made of conductive materials that may be copper and aluminum.

Earthing rods can be extended by design. It can be used with copper couplers to inter-connect many rods to acquire the required driving depth – the rod couplers provide permanent electrical conductivity and the longer copper earth rods access lower resistivity soils at lower depths.

Vertically driven earth rods are the most effective electrode for use in typically small area substations or when low soil resistivity ground conditions, For high soil resistivity ground conditions, where the rod can penetrate lies beneath a layer.

Lighting arresters are commonly using for all types of buildings. If it is not properly connected to the ground there is no use with it. If the earth rods are not placed, the excess voltage will return back to the source. If it is excess to the device, there is a chance for the failure of it and sometimes exposure can happen.

Earthing Rods

Earthing rods and their fitting accessories are used to provide the interface to ground in all soil conditions in order to achieve satisfactory earthing systems in overhead and underground electricity distribution and transmission networks – providing high fault current capacity on low, medium, and high voltage substations, towers, and power distribution applications.

Convenient to install where the subsoil condition is free from rock and boulders the earthing rod or group of copper rods can be surrounded or backfilled using a low resistance material such as Bentonite. Depending on the corrosive condition and electrical conductivity of the ground condition the earth rod can be specified to achieve safe, reliable, and long term earthing protection.

The mechanical strength of the earthing rod must withstand the abrasion and stress endured while installing with an electric or pneumatic driving rod hammer; the head of the earth rod should not “mushroom” or spread when driven. To protect all our valuable equipment from lightning or from another static current, earthing rods are playing an important role.

Like all other electrical devices and components, earthing rods are available all over the world. It is a small common element used to protect our valuable equipment easily. Electrical suppliers are the best contacting point for earthing rods. As we can't approach manufactures directly for a small quantity of these tiny elements. For residential, schools, organizations, industries, everywhere earthing rods are essential.

However, there is a lot of manufactures for it because of the high demand for earthing rods in all the type of industries. Manufactures distributing it to the authorized electrical suppliers. They can supply it to all the local points even if it is a small quantity. Earthing rods are placing in the ground around 2 feet distance from the source or building for safety. The excess current will pass through it to the ground to protect equipment.

As a commercial place, all the things are available in the United Arab Emirates. There is a lot of electrical suppliers individually or as industries. We can approach them for all our needs based on the quality or brand, we can choose the item.
