Ever attentive to your requirements, Socomec offers you services, products and customised solutions, whatever your constraints.
Our expertise in electrical power allows us to offer solutions for key applications in any electrical railway facility
For signal boxes, track beacons, lights, signalling substations and safety systems.
The LV power supply and quality of energy are assured by UPS equipment (with or without transformer), associated distribution cabinets, DC rectifiers and energy converters.
Our switching, protection and source transfer solutions are available in enclosures or can be integrated in power supply cabinets on main lines (such as ARAL, ARMATAN and ALIZET on the French network), or in switching enclosures. Our solutions have also been approved for use in the London Underground.
The automatic source transfer switch with integrated bypass is used for track signalling (e.g. normal / emergency / rescue).
Depending on the type of installation, insulation monitoring devices (IMD) will also be necessary.
To monitor LV equipment in real time and to send alerts, energy measurement and monitoring systems are installed, together with communication gateways, data loggers and embedded web server.

Protection, switching and source transfer
For power supply networks for catenary systems and overhead contact lines (OCL), including substations.
For securing the power supply to control and monitoring systems and ensuring high availability of the LV energy, we offer Uninterruptible Power Supplies (UPS or inverters) and DC rectifiers.
Our switchgear and protection solutions integrated in AC or DC protective enclosures are approved by the French rail network. For main lines, for example, they ensure protection of the batteries or auxiliary power supplies. For urban transport systems, we offer cable terminal disconnect switches (CTD), line isolation disconnect switches (LID), cleaning channel isolation disconnect switches (CCID), and emergency storage siding switches (ESS). Our energy measurement systems monitor the LV network parameters in real time, with communication gateways, data loggers and embedded web server.
These solutions can meet special requirements such as applications for outdoor use in severe weather conditions or with special fire-resistance features specifically for underground rail networks. Do not hesitate to contact us for more information.

Protection, switching and source transfer
For specific systems in main line and urban stations: telecommunications and passenger information, safety, tickets. For all service and critical buildings: IT rooms, datacentres, emergency lighting, PV production.
Critical applications are protected by UPS equipment, DC / AC converters, Static Transfer Systems (STS) and rectifiers. LV installations are protected by switching, isolation and automatic transfer equipment, as well as fuse-based protection, insulation control and electronic protection devices. For optimising energy performance in buildings, we offer a complete range of products, from measurement devices through to energy management software packages.
We also offer specific products designed for PV installations, comprising inverters, DC and AC protective devices as well as energy storage solutions.

Protection, switching and source transfer
Our specific on-board switching and protection offering fully complies with rolling stock standards, especially in terms of resistance to fire, shock and vibrations.
Adapted source transfer switches are used in order to ensure the high availability of on-board power. LV installations are protected by our switching and protection solutions. Measurement devices enable the monitoring of the main electrical parameters.
High voltage pulse transformers with high voltage withstand are used, for example, to control the thyristors used in supplying power to electric motors. High frequency transformers are used for controlling the IGBTs.
