Protecting structures & people
Introduction
Structural lightning protection
A structural lightning protection system is designed
to protect the fabric of a structure and the lives of
people inside by channelling lightning strike energy
in a safe and controlled manner to the earth
termination network.
Furse structural lightning protection employs air
termination components and down conductors - air
rods, bases, conductors and clips - to create an
effective barrier against lightning.
This approach follows the Faraday Cage principle of
lightning protection, as advocated by the majority of
national and international standards.
Earth termination
The earth termination network connects to the down
conductor network at the base of the building, and
provides the means through which lightning current is
dissipated to the general mass of earth.
Earthing components must offer both a low resistance
to earth and have excellent corrosion resistance, as
they will be buried in the ground for many years.
The range of Furse earthing products, including earth
rods, plates, clamps and inspection pits, are all
designed and manufactured in line with BS EN 50164
and BS 7430, to ensure they meet the demands
required of earth termination systems.
Additionally, we also manufacture the FurseWELD
exothermic welding system; a fast, easy and portable
way of creating high quality, fault tolerant joints
without any external power or heat source.
Lightning equipotential bonding
Equipotential bonding is designed to ensure the risk of
dangerous sparking or flashover occurring within a
structure is avoided.
Equipotential bonding is essentially the electrical
interconnection of all metallic parts to ensure no
metallic part would be at a different potential to
others in the event of lightning currents flowing in
the system.
Direct bonding can be achieved through earthing
components such as bonding clamps and flexible braids,
or for service lines with 'live cores', installation of Furse
ESP lightning current/equipotential bonding SPDs.
All Furse lightning protection products are
manufactured using the highest quality materials,
since it takes only a single substandard component to
compromise the protection of the structural lightning
protection - or earthing - system.
Fires from lightning strikes can cause major damage to structures
