Brass Square Clamps for Copper Tapes
Brass square clamps are essential components in electrical grounding and bonding systems, specifically designed to secure flat copper tapes used in earthing and lightning protection applications. These clamps are manufactured from high-quality brass, an alloy of copper and zinc, which ensures excellent electrical conductivity and corrosion resistance—critical for long-term performance in harsh environments. The square design allows for a secure and uniform connection with copper tapes, minimizing contact resistance and ensuring efficient current dissipation. These clamps are widely used in power substations, telecommunication towers, industrial plants, and railway earthing systems due to their durability and reliability. They often feature mechanical fastening mechanisms such as bolts or screws to maintain a tight grip on the tape, preventing loosening due to thermal expansion or vibration. Brass square clamps are also preferred in applications where galvanic corrosion must be avoided, as brass is compatible with copper, reducing the risk of electrolytic degradation. Compliance with international standards such as UL 467, IEC 62305, and ASTM B124 ensures their suitability for critical electrical safety applications. We also offer Brass and bronze Tape clips and DC Clips for exports.
Bronze Tape Clamps for Copper Earthing Systems
Bronze tape clamps are heavy-duty connectors used in grounding and bonding systems to securely fasten copper earth tapes, providing a low-resistance path for fault currents and lightning strikes. Made from high-strength bronze alloys, often phosphor bronze or aluminum bronze, these clamps offer superior mechanical strength, corrosion resistance, and thermal stability compared to pure copper or brass alternatives. Bronze’s natural resistance to seawater and soil corrosion makes these clamps ideal for marine installations, coastal substations, and underground earthing grids. The clamps typically feature a robust clamping mechanism, such as U-bolts or pressure plates, to ensure a permanent and vibration-resistant connection. Their high conductivity ensures minimal energy loss, making them suitable for high-voltage applications, including power plants, wind turbines, and lightning protection networks. Additionally, bronze tape clamps are often used in exothermic welding-free systems where mechanical connections are preferred for ease of installation and maintenance. These clamps meet stringent industry standards, including IEC 62561 and IEEE 80, ensuring reliability in critical electrical safety systems. Their ability to withstand extreme weather conditions and mechanical stress makes them a preferred choice for long-term grounding solutions.
