Electrification Categories
-
Cables & Wiring
Cables and wiring form the electrical backbone of railway infrastructure, connecting components across control, signalling, electrification and communication systems. Suppliers in this category offer power cables, data cables, control wiring and accessories designed for durability, electromagnetic compatibility and compliance with rail standards.
-
Catenary Equipment / OLE
Catenary equipment, also known as overhead line equipment (OLE), delivers electrical power to trains via wires suspended above the track. These systems include contact wires, droppers, insulators, tensioning devices and support structures. Suppliers in this category provide design, installation and maintenance services for AC and DC overhead electrification systems used on mainline and high-speed railways.
-
Complete AC & DC Electrification Systems
Complete electrification systems for both alternating current (AC) and direct current (DC) networks, including substations, transformers, rectifiers, switchgear, and protection equipment. Suppliers in this category offer end-to-end solutions for mainline, metro, and high-speed rail networks, covering system design, integration, installation, and maintenance.
-
Electrical Safety Systems
Electrical safety systems protect rail infrastructure, equipment and personnel from electrical faults and hazards. These solutions include surge protection devices, circuit breakers, grounding systems, insulation materials and electromagnetic shielding for components such as transformers, cables and switchgear. Suppliers in this category offer systems that ensure electrical reliability and safety compliance across rail networks.
-
Modular Components
Modular components are pre-engineered units used in railway electrification and infrastructure to enable faster, more flexible installation and maintenance. These include modular substations, switchgear assemblies, cable troughs and pre-fabricated enclosures. Suppliers in this category offer scalable, factory-tested solutions that reduce installation time, improve safety and support system upgrades.
-
Power Supply · Distribution
Power supply and distribution systems deliver and manage electrical power across railway networks, from substations to trackside equipment and on-board systems. These solutions include transformers, switchgear, cabling and load control systems. Suppliers in this category provide the infrastructure and technology needed to ensure consistent, efficient and safe power delivery for rail operations.
-
Rail Power Supplies
Rail power supplies provide electrical power to signalling equipment, control systems and other trackside infrastructure. These units ensure consistent voltage and backup support for critical operations, including interlockings, point machines and level crossing protection. Suppliers in this category offer AC and DC power supply systems, battery backups and uninterruptible power supply (UPS) units tailored for railway applications.
-
Railway Power Lines · Cables
Railway power lines and cables transmit electrical energy across the network, supplying power to trains, signalling systems and infrastructure. These may be installed overhead, trackside or underground depending on the application. Suppliers in this category provide high- and low-voltage power cables, connectors, support structures and related components designed for safe and reliable rail electrification.
-
Substations · Transformers · Rectifiers
Substations, transformers and rectifiers are critical components in railway electrification systems, used to convert and regulate electrical power for safe and efficient distribution. Substations manage voltage levels, transformers step power up or down, and rectifiers convert AC to DC for third rail and metro systems. Suppliers in this category provide complete power conversion and control solutions tailored to mainline, urban and depot environments.
