The document mainly introduces nVent ERICO's rail electrical protection solutions, including: rail infrastructure and equipment lightning protection, rail power surge protection, data and telecom equipment surge protection, rail equipment I/O port surge protection, etc.
This guide introduces nVent ERICO's surge protection solutions designed for railway infrastructure and assets. It addresses the risks of lightning strikes and transient events that can damage critical equipment in classification yards, buildings, and along the network. The document highlights the company's specialization in railway applications, offering SPDs with conventional technologies like MOVs, SADs, and GDTs, as well as novel Transient Discriminating (TD) Technology for enhanced protection and service life.
The guide details specific protection strategies for three main areas: rail power supply (primary and secondary), data and telecom equipment, and equipment inputs and outputs (I/O). It presents a 'Six Point Plan of Protection' and provides technical specifications for various product series, including the EPD, TDP, DT1, EDT2, and SGT series, covering ratings, mounting types, and compliance standards.
| Surge Rating (EPD Series Primary Power) | 40kA 8/20 μs per mode |
|---|---|
| Surge Rating (EPD Series with Flying Lead) | 206 kA 8/20 μs Aggregate |
| Surge Rating (TDP Rail Trolley Protector) | 100 kA 8/20 μs per mode |
| Surge Rating (DT1 Series) | 100 kA 8/20 μs per mode |
| Surge Rating (EDT2 Series) | 50kA to 100kA μs per mode |
| Surge Rating (TSF Series) | 20kA μs per mode, 40kA/Ph |
| Surge Rating (SGT Series) | up to 150 kA 8/20 μs per mode |
It is a hybrid surge protection design that differentiates between temporary over-voltage (TOV) conditions and very fast transient events to provide continued protection.
The company offers SPDs with conventional technologies such as metal oxide varistors (MOVs), silicon avalanche diodes (SADs), gas discharge tube (GDT), and spark gap technologies.
It is a specific protection strategy offered by nVent ERICO for railway equipment inputs and outputs (I/O) to ensure safety and reliability.
