A
unique service in the design of structural and transient overvoltage
lightning protection and earthing systems.
As an acknowledged world leader, Furse can save you time and
money in the specification, design, planning and procurement
of structural and transient overvoltage lightning protection
and earthing systems.
Given the complexity of National and International earthing
and lightning standards, confusion and misinterpretation can
easily lead to budget overruns and costly extra time on site.
So to avoid unnecessary material costs and prevent lengthy
project delays, speak to Furse.
After all, with over one hundred years technical knowledge
combined with our work as active contributors to National
and International standards, we at Furse are uniquely placed
to provide sound practical advice on any aspect of lightning
protection or earthing.
Computer Aided Design
Through the use of modern computer aided design and draughting
software, Furse can quickly produce detailed or budgetary
earth electrode and lightning protection system designs, in
compliance with any given standard.
Structural lightning and transient overvoltage protection
In order for Furse to design a structural and/or transient
overvoltage LPS, we need the following information:
|
 |
Design
standard, eg BS 6651, NFPA 780, VDE 0185, etc |
 |
A
dimensioned roof plan |
 |
External
elevations |
 |
Construction
details, eg steelwork, reinforced concrete, roofing materials,
etc |
 |
A
single line diagram indicating voltage and current for
each electrical system, eg power, data, telephones, fire
alarms, CCTV, etc |
 |
Details
of essential equipment, eg network servers, PLC controllers,
etc |
|
Power
earthing systems |
 |
Design
standard, eg BS 7430, BS 7354, Ansi Ieee Std 80, etc |
 |
A
