ENGINEERING / POWER SUPPLY

Overhead &
cable line design

From route to working drawings.

We design power lines for new construction and reconstruction, bringing the route, equipment and connection requirements together in one coordinated engineering solution.

01 / DESIGN SCOPE

Engineering every
part of your line

At a glance: the design defines the route, equipment and construction solutions. The documentation scope depends on connection requirements, the design stage and site conditions.

01

Route and crossings

Coordinate the route with land plots, roads, utilities and connection points. Develop solutions for crossings and constrained sites.

02

Overhead line

Select and position conductors and towers, carry out electrical and mechanical calculations, and design earthing and protection.

03

Cable line

Select the cable type, cross-section and installation method. Calculate loads and develop cable protection and crossing details.

04

Documentation package

Explanatory notes, plans, working drawings and equipment and material specifications. Cost estimates, construction planning and environmental sections as specified in the brief.

02 / GETTING STARTED

What we need
to assess your project

Some information missing? We can start with what you have and identify the gaps.

  1. 01

    Connection requirements, if already issued.

  2. 02

    Site location, connection points and approximate line length.

  3. 03

    Voltage, required capacity and intended use.

  4. 04

    Topographic survey and existing utility and network data, if available.

How the design progresses

  1. 01

    Confirm the brief

    Agree the scope, initial data, design stage and schedule.

  2. 02

    Develop the design

    Prepare calculations and drawings, and review key decisions with the client.

  3. 03

    Deliver the project

    Compile the documentation. Approval and follow-up responsibilities are defined in the contract.

Need help with the specifications?

Have the line voltage and length ready for an accurate estimate. For a substation or a non-standard project, request a tailored commercial proposal.

PROJECT QUESTIONS

Before
we start

What determines the design cost?

The line type and length, voltage, design stage, route conditions and documentation scope. Use the calculator for an initial estimate; the final price is agreed after reviewing your project data.

How long does design take?

We set the schedule after reviewing the route, available information and required disciplines. Design preparation and approvals involving other organisations are accounted for separately.

Can you design reconstruction of an existing line?

Yes. We need existing line data and the proposed changes, such as relocation, increased capacity, or replacement of towers or cables. We determine whether a survey is required from the available information.

Should we choose an overhead or cable line?

The choice depends on connection requirements, surrounding development, land restrictions, crossings and construction cost. If the choice is still open, we can compare alternatives during pre-design.

Are approvals and expert review included?

The approval scope and expert review support are agreed separately. We define which documents we prepare and which initial data or permits the client provides.
