Companies operating and maintaining electrical distribution networks based on ageing wooden poles face the problem of replacing the poles and protecting them from fungal and insect attack. Copper Chrome Arsenic (CCA) treatment is the approved treatment, however, is it known that this also increases every pole’s susceptibility to complete failure in a bushfire, or even when just burning off stubble in a field. When a pole fails, it can cause extended power outages or spark additional fires. Poles fallen across roads can impede public evacuations and access for emergency vehicles. Utility companies face prosecution or private legal action if they do not maintain their networks and can be shown to be at fault following the loss of property or life.
Nukote FireStop FSP, which provides utility pole fire protection and been specifically developed, tested and approved as a fire-retardant coating for CCA treated softwood and hardwood power utility poles, has solved Western Power’s problem of how to protect power poles from bushfires. The coating cures within seconds, allowing for high production rates, and is tough so resists damage during transportation and installation.
This technology is now available to all utility companies in Australia and can also be applied to steel, concrete or fibreglass poles, which are also damaged by bushfires.
The latest ultraviolet light resistant polyurea hybrid chemistry incorporates a unique intumescent system that responds to high direct heat by expanding and insulating the underlying wood from extreme temperatures and flame contact. A typical coating of 3mm is usually sufficient to provide protection for multiple small grass or bushfires.
FireStop FSP is the only treatment to have been given an “Excellent” rating under the Electricity Networks Australia “Pole Fire Test Method”, which was specifically developed to reproduce the severe conditions present in a bushfire.
