Once the type of Lightning Conductor has been chosen, it is important to consider how to fix/secure this to the structure being protected. The Kingsmill range includes fixings for both roof and wall and are designed to suit most applications, as well as materials.
DC Clips, Saddles, Clips, Hold Fasts, Adhesive Clips, Bimetallic Connectors, special roofing fixings etc.
Materials used include: high copper content alloys, aluminium and UV resistant plastics.
When choosing a suitable connector for your lightning protection design it is important to ensure that:
Galvanic corrosion – happens when there is a potential difference between dissimilar metals:
BS:EN 62305-3 contains guidance on the quantity of fixings to be used through specifying minimum distances and usage.
Lightning down conductors should each have the provision of a test or disconnecting link to separate the above and below ground conductor networks during testing.
Conductor fixings should be placed taking into account the minimum spacings recommended within BS:EN 62305, as well as practical considerations associated with building geometry.
Most Kingsmill connection components have been tested to BS:EN 62561-1 – Lightning Protection Components – requirements for connection components. They have passed both environmental ageing and 100kA impulse current testing and rated H.
