FURSE® EARTHING LIGHTNING PROTECTION QUALIT SOLUTIONS FOR SAFEGUARDING PEOPLE, STRUCTURES AND SERVICES — Introduction lightning protection Product selection guide – Conductors The first choice faced the designer a structural lightning protection system is the type conductor system used: • Choose the material required, i. Earth inspection pits Select earth inspection pit protect the earth electrode connections. Type Type foundation electrode. Conductor jointing clamps Select component for the interconnection of multiple conductors for changes direction. — 06 Conductor jointing clamps. — 07 Test clamps. — 11 Bonds metalwork. Interconnection components Crossover clamps have been specially designed for use where conductors cross part a roof network. – Air termination network The air termination network the point of connection for lightning strike. 3. Conductor network The conductor network the means of intercepting/carrying the current lightning strike safely the earth termination network. brick, stone, plastic and metal. Use strike pads connect and thus expose concealed conductors.g. 9.e. All metallic services, e. 7. High strength pits are available plastic and concrete. – Down conductor network 6. 4. Fixings Select the correct system fixings for each part of the conductor system. — 09 Earth rod clamps. — 13 Main aspects and individual components of external lightning protection system. — 01 Conductor network. 10. — 02 Fixings. The mesh size is determined Lightning Protection Level LPL. This will ensure that the vertical air rods are both solidly fixed the fabric the structure and have low resistance connection the conductor network.e. 2. flat tape, solid circular stranded 1. Earth rod clamps Select high copper content alloy earth rod clamp for the connection the earthing conductor the earth rod. Use the guidelines IEC/BS 62305-1 -3 for the correct placement conductors. 8.e. Jointing clamps will ensure low resistance, corrosion resistant connection between air termination and down conductors. — 03 Air terminals. Test clamps In order allow periodic disconnection and testing the earth termination network, select test clamp placed within the run each down conductor. Air rod bases Choose the correct air rod base. cable armouring, gas, water or steam piping, entering the building should also be bonded directly possible the earth termination network. copper or aluminium • Choose the type conductor required, i. — 10 Earth inspection pits. — 12 Equipotential bonding SPDs. Fixings are available for a wide range modern construction materials, e.g. typically consists meshed conductor arrangement covering the roof the structure. this below ground application, the clamp must ensure good electrical contact and resist corrosion throughout the lifetime the installation. Earth electrodes Choose earth electrode suit the system design i. — 08 Earth electrodes. . Electrodes can constructed individually from earth rods, earth plates, flat tape, stranded cable or any combination these. 5. — 05 Interconnection components. – Earth termination network The means dissipating the current the general mass earth. – Equipotential bonding Bonding the most commonly employed method avoiding the damaging effects of side flashing. All continuous metalwork should be considered for bonding. Air terminals Use air terminals the form vertical air rods for the protection prominent roof top features or equipment. — 04 Air rod bases
