g. . — 06 Conductor jointing clamps. 7. cable armouring, gas, water or steam piping, entering the building should also be bonded directly possible the earth termination network. — 07 Test clamps. – Earth termination network The means dissipating the current the general mass earth. Earth inspection pits Select earth inspection pit protect the earth electrode connections. this below ground application, the clamp must ensure good electrical contact and resist corrosion throughout the lifetime the installation. Earth rod clamps Select high copper content alloy earth rod clamp for the connection the earthing conductor the earth rod. — 01 Conductor network. Jointing clamps will ensure low resistance, corrosion resistant connection between air termination and down conductors. This will ensure that the vertical air rods are both solidly fixed the fabric the structure and have low resistance connection the conductor network. Interconnection components Crossover clamps have been specially designed for use where conductors cross part a roof network. — 09 Earth rod clamps. Use the guidelines IEC/BS 62305-1 -3 for the correct placement conductors. — 04 Air rod bases. brick, stone, plastic and metal. – Equipotential bonding Bonding the most commonly employed method avoiding the damaging effects of side flashing. All metallic services, e.g. Fixings are available for a wide range modern construction materials, e. All continuous metalwork should be considered for bonding. The mesh size is determined Lightning Protection Level LPL.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. Conductor network The conductor network the means of intercepting/carrying the current lightning strike safely the earth termination network. 4. 5. — 11 Bonds metalwork. 9. Air terminals Use air terminals the form vertical air rods for the protection prominent roof top features or equipment. Fixings Select the correct system fixings for each part of the conductor system. — 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. flat tape, solid circular stranded 1.
