Disconnection clamps for lightning protection are specialized components designed to provide a safe and testable disconnection point within a lightning protection system. These devices, often referred to as isolating spark gaps or test clamps, are installed in the down conductor path to facilitate periodic inspection and measurement of the system's resistance and continuity. They are typically rated for high impulse currents (e.g., 50 kA or 100 kA, 10/350 µs waveform) and are constructed from corrosion-resistant materials like stainless steel or copper alloys. The clamps ensure that the lightning protection system remains electrically continuous during normal operation but can be safely opened for testing without compromising the integrity of the overall installation.
These disconnection clamps are primarily used in external lightning protection systems for buildings, industrial facilities, and infrastructure projects. They are installed at strategic points along the down conductors, often near ground level or at accessible locations within inspection pits. Common applications include protection for telecommunications towers, solar panel arrays, wind turbines, and chemical plants where explosive atmospheres may be present. They are also essential in systems requiring compliance with standards such as IEC 62305 or NF C 17-102, ensuring that the lightning protection system can be verified and maintained regularly.
Key subcategories include standard disconnection clamps for round conductors (e.g., 8 mm or 10 mm diameter) and flat conductors (e.g., 30 mm x 3.5 mm). Typical article codes follow patterns like "DC-50-10" for a 50 kA clamp for 10 mm round conductor, or "DC-100-F30" for a 100 kA clamp for flat conductor. Other variants include clamps with integrated test sockets or those designed for use with exothermic welding connections. The main articles in this category are identified by their current rating and conductor type, ensuring compatibility with the specific lightning protection system design.
