Medium Voltage

At P.U.I. you can rely on us for the installation, replacement and capacity extension of medium voltage transformer stations and transformers. We guide the entire process, from study and design to installation and commissioning.

Installation of medium voltage transformer stations

For new-build projects or extensions, P.U.I. installs complete medium voltage stations, including switchgear, protection and the connection to the distribution network. We work closely with the grid operator to ensure a smooth connection.

• Prefab and custom cabins
• Switchgear and protection
• Coordination with the grid operator
• Compliant installation and inspection

Transformers

P.U.I. installs new MV transformers and replaces outdated units. Whether it concerns a standard distribution transformer or a special design: we select the right type and ensure a professional installation.

• Installation of new MV transformers
• Replacement of existing transformers
• Dry and oil-cooled versions
• Power adjustment and optimisation

Reinforcement and upgrade of installations

An increasing energy consumption due to heat pumps, charging infrastructure for electric vehicles and PV installations requires an adapted electrical infrastructure. P.U.I. reinforces and upgrades existing medium voltage installations so they are ready for the future.

Energy transition

The energy transition presents owners and operators of existing buildings with concrete challenges. We guide our clients in this process from A to Z: from a thorough analysis of the connection capacity to reinforcing boards, cables and cabins. The effective integration of new technologies is also fully managed by our team.

Where necessary, we provide active load management and monitoring, so that peaks in consumption are absorbed without expensive grid reinforcements.

Maintenance & continuity

Our collaboration does not end at delivery. Through annual maintenance and periodic inspections of boards, cabins and installations, we proactively ensure reliability and continuity.
