Structural lightning protection

From Furse air termination systems including air rods and strike plates to capture lightning strikes, through to our comprehensive range of down conductors and lightning protection components which channel lightning energy safely to a Furse earth termination network. Including:

  • Air termination systems
  • Lightning protection conductors
  • Conductor clips, clamps & holdfasts
  • Bimetallic connection components


The combination of Furse earth electrodes, clamps, conductors and equipotential bonding bars which provide lightning and transient overvoltage energy with an effective, low resistance route from lightning protection system to earth. Including:

  • Earth rods & conductor systems
  • Mechanical earth clamps & bonds
  • FurseWELD exothermic welding
  • Earth bars & equipotential bonding

Lightning protection & earthing design

In order for us to design a structural and/or transient overvoltage lightning protection system, we need the following information:

  • Design standard, e.g. SS555, IEC/BS EN 62305, NFPA 780, etc.
  • A dimensioned roof plan and external elevations.
  • Construction details, e.g. steelwork, reinforced concrete, roofing materials, etc.
  • A single line diagram indicating voltage and current for each electrical system, e.g. power, data, telephones, fire alarms, CCTV.
  • Details of essential equipment, e.g. network servers, PLC controllers.

To design a power earth electrode system, we need the following information:

  • Design standard, e.g. BS 7430, BS 7354, Ansi IEEE Std 80, ENA TS 41-24, etc.
  • A dimensioned site plan and overall electrical single line diagram
  • Soil resistivity survey results
  • Earth fault current magnitude (due consideration should be given to the proportion of current flowing through cable sheaths or the aerial earth wires of overhead transmission lines)
  • Earth fault current duration
