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