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