While the air terminal is the most visible component, every element plays a critical role in safely capturing and dissipating lightning energy. A weak or improperly installed component can reduce the overall effectiveness of the system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The major components include:<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">1. ESE Air Terminal<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The ESE air terminal is installed at the highest point of the structure. It is designed to initiate an upward streamer under suitable atmospheric conditions, helping intercept lightning within its intended protection zone.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">2. Down Conductors<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Down conductors create a dedicated path for lightning current to travel from the air terminal to the earthing system. These conductors are typically made of highly conductive materials such as copper or aluminium and should be routed with minimal bends to reduce electrical impedance.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">3. Earthing System<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The earthing system safely disperses lightning energy into the ground. Low earth resistance is essential for effective performance, making regular testing and maintenance an important part of any lightning protection programme.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">4. Connectors and Clamps<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">High-quality connectors and clamps ensure secure electrical continuity throughout the system. They should be corrosion-resistant and capable of withstanding harsh environmental conditions.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">5. Surge Protection Devices (SPDs)<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Although an external lightning protection system intercepts direct strikes, voltage surges can still enter through power or communication lines.
