The Earthing material that is electrically conductive and a fault current will flow to 'earth' through the live conductor, provided. This is to prevent a potentially live conductor from rising above the safe level. All exposed metal parts of an electrical installation or electrical appliance must be earthed.
There are comprehensive ranges of high quality electrical Earthing material that are widely used in earthing systems and play a vital role in all electrical systems. The accurately designed Earthing materials are available at competitive prices and safeguard both lives & equipments. The qualities of a good Earthing system include low electrical resistance, good corrosion resistance, and ability to dissipate high fault current repeatedly.
The main objectives of the Earthing are to:
Provide an alternative path for the fault current to flow so that it will not endanger the user
Ensure that all exposed conductive parts do not reach a dangerous potential
Maintain the voltage at any part of an electrical system at a known value so as to prevent over current or excessive voltage on the appliances or equipment.
Quality earth materials are commonly made from either solid copper, stainless steel or copper bonded steel. It is ideal due to its combination of strength, corrosion resistance, and comparatively low cost. Earthing materials and earthing accessories are correctly designed and installed to safeguard both lives and equipment. They have the ability to transfer current to earth with ease. Some of the main features that are needed for the earthing materials are electrical resistance to earth, good corrosion resistance, and ability to carry the required current repeatedly.
Quality earth materials are commonly made from either solid copper, stainless steel or copper bonded steel. It is ideal due to its combination of strength, corrosion resistance, and comparatively low cost. Some of the earthing materials like Earthing Strips, Earth Electrodes, Lightning Arrestors, G.I. Strips, Earthing pipes and G.I. Pipe Electrode. While purchasing earthing materials some of the points kept in mind is to buy earthing materials that are dimensionally accurate, robust construction and durable performance. Another point to be kept in mind is to check whether the earthing materials are made in compliance with security standards or not.
