Distance holder for lightning protection

Distance holders for lightning protection, also known as lightning protection spacers or air terminals, are critical components in external lightning protection systems (LPS). These devices are designed to maintain a specific separation distance between the lightning air termination system and the structure being protected, preventing dangerous flashovers. Typically constructed from corrosion-resistant materials like stainless steel or galvanized steel, these holders ensure mechanical stability and electrical continuity. They are available in various lengths and configurations to accommodate different roof types, parapets, and mounting surfaces, often featuring adjustable angles for optimal positioning of the air terminal.

These distance holders are primarily used in industrial, commercial, and residential buildings requiring a Class I, II, III, or IV lightning protection system as per IEC 62305 standards. Common installation environments include flat roofs, pitched roofs, chimneys, and water tanks. They are essential for protecting sensitive electronic equipment, structural integrity, and personnel safety in sectors such as telecommunications, oil and gas, data centers, and high-rise construction.

Key subcategories include adjustable distance holders, fixed-length spacers, and roof ridge holders. Common article codes often follow a pattern like LPDH-300, LPDH-600, or LPDH-1000, where the number indicates the separation distance in millimeters. For example, LPDH-300 denotes a 300mm holder for air terminals. Other variants include LPDH-500 and LPDH-800 for different clearance requirements.
