Lightning Conductors

The selection of the type or colour of a lightning conductor has the potential to have an aesthetic impact on the building it is installed to protect. To reduce this effect lightning conductors sometimes referred to as downtapes or roof networks are available in a selection of PVC covered colours and variations of types including flat drawn, solid circular and cable/wire. The most common type and size of conductor is the flat drawn 25x3mm with copper usually employed for earthing systems with aluminium being the material of choice above ground level. The recent upsurge in the theft of metal has resulted in a need to look at ways at protecting lightning protection installations from vandals and theft, at design stage attempting to blend the down conductors in to the building is an option which can further be complemented by installing anti vandal & theft guards to the base 3.0m of the conductor. Churchills offer a full range of lightning conductors with all variations being offered in their respective coil lengths which is detailed within the product selection section.

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 and image of a bright green 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 Churchills offer a range of UV stabilised PVC covered tapes and solid circular conductors in colours chosen to match common building materials.


Copper Conductor Ratings

For below ground earthing applications Churchills provide a large range of bare copper, tape and stranded conductors thus offering the designer of the system the correctly rated copper conductor without the need to oversize.

The following conductor ratings are based upon the recommendations of BS 7430 with an initial conductor temperature of 30°C and a maximum temperature of 250°C.
