By far the largest and most important component of any structural lightning protection or earthing
system is the actual conductor.
Selection of the correct conductor type for the installation is highly important, and is likely to be the initial
consideration of a lightning protection or earthing system designer.
A comprehensive range of Furse copper and aluminium conductors are available in each of the main world standard
formats, i.e. flat tape, solid circular and stranded. Additionally each format is available in a variety of conductor sizes,
to meet differing lightning protection and earthing requirements.
Specification will depend on whether the application is for an above ground structural lightning protection system, or
a below ground earthing installation.
Conductor colour chart
The choice of a lightning protection conductor is
usually governed by its aesthetic impact on the
structure to be protected. For many people the term
lightning conductor conjures up an image of a
discoloured copper strip running down the spire of a
church. This would clearly be unacceptable to the
owner/architect of a modern structure.
In order to reduce the impact of an external system
Furse offer a range of UV stabilized PVC covered tapes
and solid circular conductors in colours chosen to
match most common building materials.
Standard PVC colours are shown in the chart, right,
with special colours available to order.
Conductors for structural lightning
protection systems
Furse lightning protection conductors are available in
copper and aluminium, and are supplied bare or with
PVC coating (see below). For most installations, copper
is specified due to its high conductivity and anti-
corrosive properties.
The following sizes are suitable for the majority of
above ground lightning protection systems:
Flat tape conductor:
25 x 3 mm bare tape, or 25 x 3 mm PVC covered tape
Solid circular conductor
8 mm diameter bare or PVC covered solid circular
conductor
Stranded conductor
70 mm2 bare or PVC covered stranded conductor
