Expansion Bonds absorb movement caused by the electromechanical effects of a direct lightning strike to the Lightning Protection Network. They can also absorb movement due to temperature and climate changes.
Material: Bare Copper, Tinned Copper, or Aluminium
Standard: BS:EN 13602
Other sizes, materials, hole sizes, etc available on request.
An important part of a Lightning Protection System (LPS) is that electrically continuous parts of a structure must be bonded into the Lightning Protection network. The purpose of this bonding is to ensure that, in the event of a lightning discharge, any sparking of flashover of the lightning current to conductive parts of the structure, for example, water pipes, cables, etc are avoided.
