Ideal for new installations or retrofits, our Friction Springs provide electrical substations with base isolation. Compact and maintenance-free, these devices consist of fire-resistant spring steel and outer and inner mating rings with conical contact surfaces. They also don't require cranes or lif…
Electrical substations are some of the most important facilities to protect during an earthquake. The equipment within these stations and transmission yards are essential to providing power to millions of homes, as well as to important public institutions like the police, fire department, hospitals and other first responders.
In our last blog post, we explored the ways friction springs provide vital protection from devastating earthquakes. These damping components rely on tapered mating rings, which overlap under load and dissipate up to two-thirds of introduced energy. Recognizing the critical role of these friction springs, one Pacific Northwest utility has taken a proactive approach to protecting its facilities from the predicted “Big One.”
In 2013, a 6.5-magnitude earthquake gripped Wellington, New Zealand—causing widespread damage across the city. While many of the buildings were destroyed, a student dormitory managed to make it through the ordeal unscathed. How?
Friction springs are carving out a growing niche in the seismic protection applications. Working as part of a sliding joint assembly, friction springs can protect buildings, power generation equipment and other infrastructure from eathquake damage.
