DELTA POWERS SEAMLESS CONNECTIVITY FOR THE WESTERSCHELDETUNNEL IN THE NETHERLANDS

The Westerscheldetunnel, a vital infrastructure asset managed by N. V. Westerscheldetunnel on behalf of the Province of Zeeland, is the longest tunnel in the Netherlands at 6.6 kilometers underwater.
power solution that directly addressed the tunnel’ s requirements.
As a key transportation route, the tunnel ensures smooth connectivity between regions, making its
uninterrupted operation critical. A power outage in such an environment could jeopardize the safety of
travelers by disrupting critical systems, such as lighting, ventilation, and signaling. Ensuring these systems
remain operational, even during power disruptions, is essential to safeguard the lives of those driving through the tunnel.
Delta addressed this vital need by installing state-of-the-art IPT-50kVA Industrial Power Transformer-based UPS systems, showcasing its expertise in delivering comprehensive turnkey solutions for industrial environments.
Innovative Tailored Power Solutions
The UPS system previously used in the Westerscheldetunnel had reached the end of its lifespan and needed to be replaced. The complex logistics of installing a new system within the tunnel presented significant challenges. To address these issues, a solution was needed that could ensure reliable power delivery while optimizing space and operational efficiency.
To meet these requirements, Delta supplied its newly launched IPT-50kVA UPS units, each with a compact footprint( 600 x 830 x 1420 mm), making them ideal for installations where space is limited. These systems feature advanced technologies, including IGBT rectifiers for low total harmonic distortion( iTHD < 3 %) and inverter-integrated isolation transformers, enhancing short-circuit capability and load separation. These
innovations provided a reliable and manageable
Efficient Implementation in a Record Time Frame
In December 2023, Croonwolter & dros, acting on behalf of N. V. Westerscheldetunnel, partnered with e-Power to implement Delta’ s IPT-50kVA systems during the second phase of the project. Delta’ s product management and engineering teams collaborated closely with e-Power to deliver the UPS systems on a tight schedule, meeting the demanding deadline.
The new systems have significantly enhanced the tunnel’ s operational efficiency. Features such as a userfriendly 10-inch waterproof touch panel and advanced event analysis capabilities have reduced maintenance time and costs. Additionally, the compact design also streamlined installation, optimizing project and labor management.
Ensuring Safety Through Reliable Power
The reliability of the IPT-50kVA UPS systems plays a critical role in ensuring safety within the
Westerscheldetunnel. These systems provide seamless backup power, ensuring that essential functions like signaling, ventilation, and lighting remain operational even during power outages. Such redundancy is vital to
