Modern U.S. railway systems operate in demanding electrical environments where reliability and safety are non-negotiable. From high-speed passenger rail to freight corridors stretching across diverse climates, electrical surges caused by lightning strikes, switching operations, and power fluctuations pose serious risks. This is where Metal Oxide Surge Arrestors play a critical role.
At Swartz Engineering, we understand that railway infrastructure depends on uninterrupted power and protected signaling systems. Metal oxide surge arrestors are designed to safeguard critical railway assets such as traction power systems, substations, signaling equipment, and communication networks. Unlike older silicon carbide technologies, metal oxide arrestors respond faster, provide superior energy absorption, and maintain stable performance over time.
Railway operators across the U.S. rely on these arrestors to reduce equipment damage, minimize service disruptions, and improve overall system resilience. When a surge occurs, metal oxide surge arrestors quickly divert excess voltage away from sensitive components, helping prevent costly failures and unplanned downtime. This protection is especially important in rail environments where even a brief electrical fault can impact safety, schedules, and public confidence.
Swartz Engineering works closely with railway engineers and project managers to ensure the correct selection, specification, and integration of Metal Oxide Surge Arrestors for each application. Whether supporting new rail expansions or upgrading legacy systems, our solutions are engineered to meet industry standards and withstand harsh operating conditions.
As U.S. rail networks continue to modernize and electrification expands, dependable surge protection becomes more essential than ever. By investing in proven metal oxide surge arrestor technology, railway operators can protect infrastructure, enhance operational reliability, and support long-term system performance.
Swartz Engineering remains committed to delivering practical, high-quality surge protection solutions that keep America’s railways moving safely and efficiently.
