When powering one of the world’s most advanced supercomputers, reliability and performance are non-negotiable. That’s why the Leonardo Data Centre, hosted in the Bologna Technology Park and managed by Cineca, chose Graziadio’s GDA Busbar Trunking System.

What is GDA?

GDA is a busbar trunking system designed for electrical current distribution, ranging from 63 to 2500 A. It’s engineered to outperform traditional cabling solutions, especially in environments that demand scalability, flexibility, and robust protection.

Why GDA Was Chosen for Leonardo

✅ Flexible Assembly

GDA can be installed horizontally or vertically, making it ideal for complex infrastructure layouts. Its monoblock joints allow for quick assembly, saving time and reducing installation costs.

️ High Protection Rating

With a protection level of up to IP55, GDA is suitable for humid environments and offers resistance against dust and solid particles, ensuring long-term reliability even in challenging conditions.

Easy Expansion

Need to scale up? GDA makes it simple. Tap-off boxes (ranging from 32 to 1250 A) can be added to either side of the trunking system. They’re lightweight yet durable, enabling low-cost expansion without disrupting existing infrastructure.

Built to Resist

Thanks to its aluminium casing, GDA resists corrosion and short circuits. It also provides high heat dissipation, making it suitable for environments with limited air circulation.
