About
The process of transmitting current from the electrical appliances to the ground through a metallic strip of low resistanceis known as strip earthing. Hot-dipped galvanized strips are used for earth stripping and have a diameter of 6mm. These strips are laid horizontally in trenches with a depth of 0.5m.Superior Corrosion Resistance and LongevityUtilizing a hot dip galvanized finish, these GI earthing strips deliver exceptional protection against corrosion for more than 20 years under standard conditions. This enhances reliability in both indoor and outdoor installations, even in humid or aggressive environments.
Versatile Installation MethodsOur earthing strips are designed for flexible mounting optionseither fixed in trenches or directly onto surfaces, using clamps or bolts. The strips accommodate a minimum bending radius suitable to their thickness, ensuring proper installation in a variety of layouts and grounding systems.
Customizable and High ConductivityOffered in several standard and custom dimensions, these strips adapt to project-specific requirements. The metallic, bare finish ensures optimal electrical conductivity, supporting total current ratings up to 1000A, making them ideal for demanding electrical installations.
FAQs of Earthing strip installation:
Q: How are GI earthing strips typically installed?
A: GI earthing strips are installed either by surface mounting or by laying in trenches. The strips are secured in place using suitable clamps or bolts, ensuring they maintain solid contact and structural integrity for effective grounding.
Q: What factors determine the appropriate thickness or size for my application?
A: The required thickness and width depend on factors such as maximum current load, installation environment, and specific electrical codes. Common sizes include 25mm x 3mm or 30mm x 5mm, but custom dimensions are available on request.
Q: When should I inspect or maintain the earthing strips?
A: It is recommended to conduct periodic visual inspections to check for mechanical damage, corrosion, or loose connections. Under nominal conditions, maintenance is minimal due to the galvanization but should be included in your facilitys regular safety checks.
Q: Where can these earthing strips be used?
A: These GI earthing strips are suitable for both indoor and outdoor environments, including substations, industrial sites, commercial buildings, and other settings requiring electrical grounding and protection up to IP65 with proper installation.
Q: What benefits do hot dip galvanized strips provide over painted strips?
A: Hot dip galvanized strips offer much greater corrosion resistance compared to painted alternatives, significantly extending their operational lifespan (over 20 years) and maintaining electrical performance in adverse weather and high-humidity conditions.
Q: How does the strips current carrying capacity relate to its size?
A: The maximum current carrying capacity primarily depends on the strips cross-sectional arealarger and thicker strips can carry higher currents, up to approximately 1000A for the biggest standard profiles.
Q: What makes these strips suitable for high-humidity or outdoor use?
A: The galvanization process protects the strips against rust and environmental degradation, allowing them to function efficiently in humid, wet, or otherwise challenging outdoor settings without performance loss.
