Powering India's Rail Network Through Precision Fabrication and Turnkey Execution

We support India’s railway electrification mission with end-to-end Overhead Electrification (OHE) and allied civil + structural execution, delivered with fabrication precision, electrical integration capability, and on-ground project discipline across terrains and timelines.

What is Overhead Electrification (OHE)?

Overhead Electrification refers to the system of overhead wires-comprising conductors, insulators, fittings, and suspension structures that deliver 25 KV AC electric traction to railway locomotives.

It is the backbone of electric railway operations, offering:

  • Operational efficiency with lower maintenance costs
  • Environmental benefits by replacing diesel traction
  • Higher throughput for freight and passenger traffic
  • Strategic value in energy conservation and cost optimization

Key Components of OHE Systems

Zetwerk provides design, fabrication, and installation of complete OHE assemblies, including:

Catenary and Contact Wires for current transmission

Brackets, Tubes, and Register Arms for structural support

Droppers and Steady Tubes for mechanical balance and positioning

Jumpers and Insulators for safety and continuity

Traction Power Infrastructure

Zetwerk also engineers and constructs supporting traction infrastructure.

Traction Substations (TSS)

  • Convert incoming high-voltage supply (220/132/110/66 KV) to 25 KV AC for railway traction
  • Installed every 30–40 km based on traffic load

Switching Posts

Sectioning & Paralleling Posts (SP) and Sub-Sectioning & Paralleling Posts (SSP) are used to balance the load across different phases of the grid and to isolate faults, ensuring seamless train movement

Signaling & Telecommunication (S&T)

To ensure safety and communication, Zetwerk integrates advanced S&T systems as part of our railway projects:

Signaling Systems

Enable safe train movements via electronic interlocking and centralized traffic control

Telecommunication Systems

Connect train crews, control centers, and field staff for real-time operations
