WHY GI STRIP IS REQUIRED FOR EARTHING
WHY GI STRIP IS REQUIRED FOR EARTHING
Many use GI (Galvanized Iron) strips for earthing purposes due to several important reasons.
Electrical Conductivity:
GI strips have good electrical conductivity properties, which allows them to effectively carry electrical current from the grounding system to the earth. The low resistance of GI strips ensures efficient dissipation of fault currents, lightning strikes, or electrical surges into the ground.
Corrosion Resistance:
Galvanized iron strips are coated with a layer of zinc, which provides excellent corrosion resistance. This coating protects the GI strip from rust and deterioration caused by moisture, chemicals, and other environmental factors. Corrosion resistance ensures the longevity and durability of the earthing system.
Mechanical Strength:
GI strips have high mechanical strength, making them suitable for grounding applications. They can withstand mechanical stress, pressure, and physical impact without deforming or breaking. The robustness of GI strips ensures the integrity and reliability of the earthing system.
Availability and Affordability:
GI strips are widely available in the market and offer a more affordable alternative to other earthing materials, such as copper. This makes them a cost-effective option for grounding applications, especially in large-scale installations or projects with budget constraints.
Compatibility with Grounding Components:
GI strips are compatible with various grounding components, such as electrodes, clamps, connectors, and earth pits. They can be easily connected and secured to create a robust grounding system. The compatibility of GI strips with other grounding components simplifies installation and maintenance processes.
Widely Accepted Standard:
Many electrical standards and regulations widely accept and specify the use of GI strips for earthing. Compliance with these standards ensures the safety and reliability of the earthing system. It also facilitates consistency and interoperability between different grounding systems and equipment.
Conclusion
Although many use GI strips for earthing, they should consider specific project requirements, local regulations, and industry standards. In some cases, engineers prefer alternative materials like copper for its higher conductivity or suitability for specific environmental conditions. Consulting with a qualified electrical engineer or grounding specialist can help determine the most suitable material for your specific earthing needs.
