Lightning protection

Introduction

When designing a structural lightning protection system using the Faraday Cage principle, it is possible

to use one or more of a variety of available conductor systems; namely flat tape, solid circular or cable

& wire (stranded).

The decision about which type to use is often based more on country-specific historical preferences or aesthetic

considerations than the superiority of one type over another. High quality Furse conductors, plus appropriate

fittings, are available for all three systems.

Flat tape conductor system

Flat tape conductors are easy to install, with no need to straighten

for a neat finish. Available in copper or aluminium, flat tape can be

installed bare or with a choice of PVC coverings, to enable the tape

to blend with modern building fabrics.

Tinned copper tape is also available for applications that require

additional protection measures, and copper braid is available for

use where flexibility is necessary, e.g. on moving installations like

gates or doors.

Furse copper tape is approved to BS EN 13601, whilst Furse

aluminium tape is approved to BS EN 755-5.

The Furse range of conductors is complemented by a complete range of fittings, including clips, clamps, holdfasts

and bimetallic connectors.

Fittings are designed to conform to the BS EN 50164 series of product standards governing performance of

lightning protection components which form part of an external lightning protection system (see also

pages 284-285).

Solid circular conductor system

Solid circular conductors can be used in applications where

aesthetic considerations are important.

The 8 mm diameter solid circular range is less conspicuous than the

flat tape system, and lends itself much better to being concealed.

Available in copper or aluminium, solid circular conductors can also

have PVC coverings.

A coil of circular conductor can be quickly installed, being easy to

bend in any plane, and only needing a straightening tool to give a

very neat finish.

Furse copper solid circular conductor is approved to BS EN 13601,

whilst Furse aluminium solid circular conductor is approved to

BS EN 755-5.

Stranded conductor system

The Furse range of soft drawn stranded conductors is available in

copper, either bare or PVC insulated, and complies with the US

standard NFPA 780.

Furse soft drawn stranded conductor is approved to BS EN 60228,

whilst our PVC insulated stranded conductor is approved to

BS 6004.
