Rectifier substations

Catenary (new lines)

Catenary Upgrade

Auxiliary installations

We construct substations, both open air and GIS, for high speed lines with 1x25 kV and 2x25 kV feeding systems.

We install transformer centers and energy distribution systems to feed installations around a railway facility.

For DC electrified railways, we build rectifier substations.

We provide EPC turnkey projects for the installation of catenary system in new lines or existing lines to be electrified.

We build and install autotranformer centers for high speed lines with 2x25 kV feeding system.

When existing catenary systems may require, we renew and upgrade existing installation without service interruption.

Efficiency Savings Delivered…

By means of:

- Detailed engineering

- Investment in plant & machinery

- Planning & Programing

- Quality control

INABENSA Foundations construction: From digging to drilling

  Excavator works for a long time

  Big surface affecting other systems

  Difficulties on mast adjustment

  High costs on concrete, labuor & shuttering

Gravity foundations…

  Faster drilling works

  Smaller surface

  Easy reference for mast location & adjustment

  Investment in plant and machinery

  Quality control

Cylindrical foundations…

INABENSA Pole Erection

  Detailed engineering

  Material procurement

Pole erection is optimised work if all fittings have been pre-assembled

Assembly of all fittings prior to pole erection

  Safer work

  Cost optimisation

  Execution period improvement

INABENSA Cantilever assembly and transportation to site

Key factors for a successful cantilever assembly

Cantilever design

 Actual position from mast to track

 Design and design quality control

Cantilever assembly

 Manufacturing jig design

 Assembly and assembly quality control

INABENSA Cantilever assembly and transportation to site

Cantilever installation: marking and transportation

Ordered transportation to site

 Unique labeling of each cantilever identifying mast number and location.

 Cantilevers must be stacked in correct order to avoid time wasting looking for the right one and transported in “goal post” cradles to prevent damage.

INABENSA Catenary wiring: the quality factor

 Performance

  1st step: Laying messenger wire on pulleys

  2nd step: Tensioning MW

  3rd step: Midpoint anchor installation

  4th step: Laying contact wire

  5th step: Tensioning CW

  6th step: Pulleys removal

 Quality

  Variable wiring speed: Micro undulations might

appear

 Risks

  Copper wires on pulleys are easily stolen
