Why Flexible Busbars in Data Centres?

UPS systems and data centre power distribution run under continuous load, 24 hours a day, 365 days a year. Every watt of power loss at a connection point becomes waste heat that the cooling system has to remove. In an industry that measures energy efficiency in PUE (Power Usage Effectiveness) and counts every improvement after the decimal point, the losses across dozens of high-current connection points add up to a measurable amount.

Press-welded flexible busbars provide consistently low-resistance connections that remain stable over years of uninterrupted operation. The homogeneous copper joint without solder or flux means a negligible millivolt drop across the transition. Compared with cables, the flat design offers more surface area for heat dissipation and helps prevent hotspots at the contact points.

The flexible design absorbs thermal expansion in densely packed cabinets and busbar trunking without transferring forces to adjacent components. During expansions or retrofits, it simplifies installation, as rigid bars no longer need to be precisely preformed and aligned.
