Pole Upgrading and Hardening
Thousands of poles in service today, although adequate at the time of installation, can no longer safely carry the loads they are required to support. The addition of new distribution lines, telecom equipment, and broadband infrastructure have increased loads beyond the capabilities originally intended, compromising the structural reliability, resilience, and safety of poles across America.
System Hardening Program
Ensuring the health and structural resilience of the wood pole plant is a key component of every utility's grid modernization investment.
A successful, programmatic approach to wood pole asset life extension can be implemented at a fraction of the cost of the utility's overall smart grid investment. These life extension programs include thorough inspection, preservative treatment application, and where applicable, the installation of strength improvement trussing systems.
These programs aim to preserve and restore pole strength to extend the useful life and improve the resilience of these critical assets. The results of such programs deliver well-documented financial, operating, and system resiliency returns.
Osmose's family of wood pole improvement products are used to enhance the structural resilience of the grid. Specifically, Osmose C and C2 trussing systems act as a structural hardening solution by improving an overhead circuit's resistance to extreme weather events. Without the restored strength the truss provides to the weakened pole, the overall circuit is at greater risk of a prolonged outage during a significant weather event.
Upgrade Capacity with the ET-Truss™
A utility’s grid resiliency is positively affected with a robust pole inspection and restoration program. Weakened poles discovered during inspection and rehabilitated with an Osmose C or C2-Truss will help minimize the number of wood poles needing attention, as utility crews work to restore power to the grid after a significant weather event.
The Osmo-ET-Truss™ works in conjunction with sound wood poles to create a combined bending capacity greater than the original pole.
- Upgrade pole bending capacity by an equivalent 1, 2, 3, or more classes
- Save money – the cost of upgrading is often 1/3 or less than the cost of replacement
- Avoid the extra effort and delays associated with coordinating change-outs
- Upgrade an entire line without service interruption
Extensive testing has verified the theoretical expectations of the ET-Truss design and Mother Nature has been putting it to the test since the early 2000's.
Whether a pole owner is looking to correct overloaded poles or simply add bending capacity to improve structural resilience to extreme weather, the ET-Truss is a proven lower cost alternative to pole replacement.
