Large-scale infrastructure projects demand electrical systems capable of operating reliably in extreme environments. The Woodsmith Mine development in North Yorkshire represents one of the UK’s most ambitious mining projects.

Electro-Wind supplied specialist transformer solutions supporting underground operations across the site.

Project Overview

The Woodsmith Mine includes an extensive underground tunnel network designed to transport millions of tonnes of mineral resources annually.

Electrical infrastructure required transformers capable of operating within:

• High-humidity environments

• Restricted tunnel installations

• Continuous heavy-load conditions

Engineering Requirements

Supplied transformer systems included:

• Single-phase and three-phase units

• Voltages up to 3.3kV

• High-capacity distribution transformers

• Systems supporting lighting and heavy mining equipment

Each unit was customised for installation constraints unique to underground mining infrastructure.

Overcoming Installation Challenges

Engineering teams addressed:

• Limited access routes

• Ventilation restrictions

• Environmental protection requirements

• Compliance with mining safety regulations

Robust enclosure and cooling strategies ensured operational reliability after installation.

Supporting Critical Infrastructure

Once deployed, the transformer systems became integral to powering ongoing mine construction and operational systems.

Reliable electrical supply enables safe excavation, transport operations, and long-term production capability.
