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

Zetwerk's Infrastructure division plays a pivotal role in India's electrification drive, delivering end-to-end Overhead Electrification (OHE) and related civil and structural works for the Indian Railways.

Leveraging deep expertise in fabrication, civil execution, and electrical integration, we provide scalable and reliable infrastructure solutions across diverse terrains and timelines.

Our commitment to quality and execution at scale positions us as a trusted partner for India’s largest railway electrification projects, aligning closely with the country’s push towards 100% electrification, improved energy efficiency, and reduced reliance on diesel.

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

Zetwerk’s Scale of Operations

We deliver turnkey electrification projects across India with comprehensive in-house capabilities spanning fabrication, project management, and civil execution.
