Grid Hardening with FireStrong Poles
A weak power grid with aging wooden utility poles can easily go down in fire and can be very difficult and costly to restore. Exposure to fire causes a standard wood utility pole to lose area from its design section. As a result, its engineering properties can change, losing strength and stiffness. Compromised poles must be replaced.
FireStrong utility poles help fire-affected communities get back on their feet faster. Made with a custom-engineered vinyl-ester resin, an additional fire-resistant FRP shield keeps these utility poles standing strong when subjected to fire. FireStrong poles have low thermal conductivity and high dielectric strength. Each pole is equipped with an irreversible temperature monitoring system that helps utility companies know when a pole has had critical fire damage and must be replaced.
FireStrong poles were designed for chaparral fires that typically last less than three minutes with a temperature threshold of 2,100°F. These utility poles have been tested in full section in wildfire simulation and post-tested to determine full section strength retention.
FireStrong poles are more sustainable than wood, steel or concrete alternatives:
- 5 times lighter than wood poles
- Better tensile strength than steel
- Use less carbon to transport
- Require fewer labor hours to install and maintain
- Double the typical service life of a wood pole – sometimes more
- Don’t leach chemicals into the surrounding area
