By far the largest and most important component of any structural lightning protection or earthing system is the actual conductor.

The conductor network is the means of intercepting/carrying the current of a lightning strike safely to the earth termination network. Use the guidelines of BS EN 62305-1 & 3 for the correct placement of conductors.

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 is available in each of the main globally recognised 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.

Conductors for structural lightning protection systemsFurse lightning protection conductors are available in copper and aluminium, and are supplied bare or with PVC coating. For most installations, copper is specified due to its high conductivity and anticorrosive properties.

The following sizes are suitable for the majority of above ground lightning protection systems:

Flat tape conductor25 x 3 mm bare tape, or 25 x 3mm PVC covered tape

Solid circular conductor8 mm diameter bare or PVC covered solid circular conductor

Stranded conductor70 mm2 bare or PVC covered stranded conductor

Where permanent connections are not appropriate, mechanical clamps offer the ideal solution. These are typically used on smaller scale installations where periodic disconnection for testing is required.

All mechanical clamps are manufactured from high copper content alloy. They have high mechanical strength, excellent corrosion resistance and conductivity.

Our range of earthing clamps are designed for connection of conductors to earth rods, reinforcing bars, steam pipes, handrails etc Manufactured to offer corrosion resistance, conductivity and mechanical strength, these are essential considerations in an earthing design to ensure an earthing system remains operative for many years.

All earth rod clamps have high strength copper alloy bodies and screws e.g. aluminium bronze, phosphor bronze etc., commercial brass is not used.

The way cables are fixed into place is very important. Poor clamping can damage the cable or put undue strain on cable terminations or the cable conductors, sheathing or insulation. Fault currents in Trefoil cable systems can only be properly controlled with the use of tested, fault rated cable clamps. Secure and easy to use cable cleats ensure data and communications cables are installed rapidly, and free from damage. All cables from data and communications to LV, HV and EHV cables have special clamping requirements to ensure the safe, long term performance of the cable system. ASWATHY is a major manufacturer and supplier of cable clamps to projects around the world. Our expert staff have many years of experience in the design and manufacture of quality cable clamps. ASWATHY designs and manufactures a range of Trefoil cable clamps as well as supplying a range of other cable cleats. This ensures we have the cable clamps and cleats to suit all cable types and applications.
