Fibre optic networks for the power industry

Optical ground wire on overhead lines, routes across sites, links from substations to the control centre. We build the route and prove with measurements that it is sound.

What we do

Fibre in the power industry has its own rules — the route runs along live towers, into the cable ducts of a substation, or across a site that is still being built. We do it where we also build the line itself, so there are no two companies to coordinate.

Overhead high-voltage line

Optical ground wire on MV and HV lines

Optical fibre carried along the towers together with the conductors. We string the cable, fit and terminate the joint boxes and bring the route into the substation or transformer station.

  • Installing optical ground wire on overhead lines
  • Optical joint boxes on towers and poles
  • Fixings, vibration dampers and route protection
  • Bringing the route in and terminating it in the substation or station
  • Work on the line by our own certified technicians
Enquire about optical ground wire

Optical joint boxes and optical ground wire diagnostics are part of our maintenance standard — on the lines we look after, we inspect and measure them on a regular cycle.

Ducts and routes across sites and residential developments

When we build a local distribution system on a new site or development, we lay the fibre ducts in the same trench. That costs less than digging twice.

  • Ducts and routes in the same trench as the cables
  • Blowing the fibre cable in, splicing
  • Preparing the route for the connectivity provider
  • Termination in cabinets and plant rooms
  • Survey and as-built documentation

Linking substations and stations to the control centre

Fibre is how data from the station reaches the control room. We bring the route all the way to the cabinet, terminate it and connect it to the control system.

  • Optical distribution frames and route termination
  • Fusion splicing and measurement of the joints
  • Connection to the control system and remote control
  • Routes through the cable ducts and tunnels of the substation
  • Working alongside the control-system supplier
Enquire about a link

We do this as part of a substation or switchyard job, or on its own for equipment somebody else built.

Testing and diagnostics of fibre routes

A finished route has to be measured and the result documented. We measure continuity and attenuation, trace where the route is misbehaving and hand over the test report.

  • Measuring optical continuity and route attenuation
  • Locating faults and points of damage
  • Diagnostics of optical ground wire on the lines
  • Test reports for handover and for the documentation
  • Repeat measurements as part of regular maintenance

Why give it to us

01

We can also build the line the fibre hangs on

We build distribution networks up to 110 kV. So we are not climbing the tower for the fibre alone, and we know what may and may not be up there.

02

One trench, two jobs

If we are building your distribution system, we lay the fibre ducts at the same time. No second trench and no second company.

03

Work without an outage

We can maintain equipment up to 35 kV using live-line working, so nothing has to be switched off for work on the route.

04

24/7 emergency cover

We respond to faults around the clock — outside working hours, at weekends and on public holidays.

How a job runs

01

Send us the brief

Where the route runs from and to, how many fibres, and what will be connected to it.

02

Route survey

We walk the route and check the towers, the access and where it can actually go. This is where most money is saved.

03

Quotation with a date

You get a quotation with a clear scope and a delivery date.

04

Delivery

Route, splicing, termination — with the site live if that is what it takes.

05

Measurement and handover

We measure the route and hand over the test reports and as-built documentation.

Not sure where the route should go?

Give us a call and we will go through it together — from fibre count to the way it is laid.

Enquiry

Send us the brief and we will quote

Drawings, a route layout or a description of where the fibre should run is enough. If you have none of those, just call.
