Railway Electrical Protection

Lightning strikes can cause catastrophic damage to critical rail infrastructure and equipment. Unexpected transient events or momentary bursts of extremely high voltages can occur even during normal operations, which is why railway electrical protection is an important part of safe, reliable operations. nVent ERICO offers solutions that provide critical electrical protection for railway properties and assets including: classification yards, buildings and structures, bungalows, movable bridges and other areas throughout the network that contain sensitive equipment. This product range includes solutions for direct strike lightning protection, grounding and bonding, as well as surge protective devices (SPD) for railway communication/signaling equipment and systems.

nVent ERICO is a leading global supplier of SPD, serving a diverse range of industries throughout the world with surge protection solutions for equipment power, equipment inputs and outputs as well as data and telecom transmitting equipment. With our specialization in railway electrical protection, nVent ERICO offers many SPD that are specifically designed for rail applications. We offer SPD with conventional surge technologies such as: metal oxide varistors (MOVs), silicon avalanche diodes (SADs), gas discharge tube (GDT) and spark gap technologies. With a long-term commitment to R&D, and a world class electrical engineering lab, we have developed novel nVent ERICO surge suppression technologies that overcome the limitations of conventional methods to provide an enhanced level of protection.
