What we do

Medium Voltage

Design, construction and maintenance of 20 kV Medium Voltage installations: substations, lines, transformers and switchgear for industry, solar and public projects.

Medium Voltage (MV) installations demand specialist knowledge, certified personnel and strict compliance with safety regulations. We take projects from design and permitting through construction, testing and connection to the HEDNO network, for customer substations, private MV networks and generation plants.

What Medium Voltage projects include

An MV project usually comprises the substation or kiosk with its transformer, MV switchgear, earthing, Low Voltage panels and the connection line to the distribution network. Each element is designed to cover the load, short-circuit levels and protection needs of the customer.

Connecting to HEDNO

We coordinate with HEDNO on the final connection offer, connection-point specifications, inspections and final energisation, reducing the risk of delays and redesign.

Safety and maintenance

Work on Medium Voltage is carried out only by trained personnel following safety procedures. We also offer preventive maintenance programmes for substations to limit faults and unplanned outages.

Frequently Asked Questions

When is a Medium Voltage substation needed?

Usually when the requested capacity exceeds the limits of a Low Voltage supply, such as in industry, large buildings and generation plants.

Do you handle permitting?

Yes, we support the process and coordinate with HEDNO and the relevant authorities.

Do you offer substation maintenance?

Yes, through preventive maintenance and protection-testing programmes.
