Last-Minute Surge Protection for a Large US Data Center Project

A major contractor in the United States was building a new large-scale data center. Design, schedule and budget were all locked in – until, during construction, a critical gap was discovered:
surge protection for the high-voltage system had been completely overlooked.

With construction already underway and a potential site-wide delay looming, the contractor urgently needed a reliable producer of high-voltage surge arresters – and found TRIDELTA Meidensha almost by chance.

What happened? High-Investment Project, Critical Oversight

Large, high-investment US data center project already in construction phase
Surge protection for the high-voltage supply was missing from the original design
Risk of a costly construction stop and delay of the entire project
Contractor required:

technically suitable high-voltage surge arresters
full compliance with the project’s technical specifications
delivery from order to shipment in max. 8 days

Any delay in sourcing the right arrester solution would have jeopardized the schedule, budget, and trust in the contractor.

Engineering, Production and Logistics – All in Fast-Track Mode

The contractor shared the technical requirements and system data with Tridelta Meidensha
Our engineering team quickly:
- reviewed the electrical parameters
- defined suitable high-voltage surge arrester types
- prepared a technically sound quotation
After order placement, we switched to fast-track production:
- prioritised manufacturing slot for the required arrester quantity
- close coordination between engineering, production and logistics
We met the critical requirement:
- from order to shipment in 8 days, including express dispatch to the US job site

Despite the extreme time pressure, no compromises were made on product quality, testing or documentation.

Project Secured – and a New Partner Gained

The surge arrester solution arrived on time, avoiding a construction stop
The data center project continued according to schedule
High-voltage equipment is now protected by reliable surge arresters tailored to the project’s requirements
The contractor gained a trusted surge protection partner for future projects
