While everyone is debating how many megawatts of power AI data centers require, I find myself increasingly focused on a much smaller question:
How is all that power actually connected?
Data Center World Power 2026 is set to open in Dallas.
Industry discussions will center on AI, liquid cooling, energy storage, grid integration, megawatt-scale power systems, and next-generation infrastructure.
These are certainly important.
But once a data center is actually up and running, the electric current doesn’t just stay within the system architecture diagrams shown in PowerPoint presentations.
It must ultimately flow through busbars, cables, terminals, and a succession of connection interfaces.
And it is precisely in these inconspicuous spots that many long-term risks lie hidden.
The reliability of a connection point is never merely a matter of “metal touching metal.”
Take mechanical connectors, for example.
Surface tin plating isn’t just about making the product look shiny.
A complete, stable plating layer helps protect the base material and reduces the risk of the connection interface being compromised by oxidation or environmental factors.
Similarly, the jointing compound pre-applied to the connection area is far from an optional accessory.
It plays a crucial role in preventing air and moisture from reaching the contact interface and helps mitigate the impact of oxidation layers on long-term electrical contact performance. Industry guidelines for electrical connections have long regarded protective plating and the proper use of jointing compounds as vital elements of connection reliability.
Viewed in isolation, these design details seem very “small.”
They aren’t as advanced as chips.
They don’t grab attention like liquid cooling systems.
They might not even appear in data center promotional videos.
Yet, AI infrastructure has a very practical characteristic:
The higher the power density, the more demanding our requirements become regarding the long-term stability of every single connection point.
Truly mature electrical infrastructure isn’t just about getting the most expensive equipment right.
It is about considering materials, contact interfaces, and installation consistency—even for those connection points buried underground, tucked away in cable trays, or left unvisited for years after installation. This is also an aspect of the discussion around AI data centers that is easily overlooked:
The cloud may be digital.
But its reliability is still physical.
When we talk about next-generation data centers, perhaps we should ask one more question:
Within the entire power chain, which seemingly insignificant components actually have the least margin for failure?#DataCenter #AIInfrastructure #DataCenterPower #PowerInfrastructure #ElectricalInfrastructure #MechanicalConnector #ShearBoltConnector #CableAccessories #CableConnection #CableTermination #PowerDistribution #ElectricalEngineering #MediumVoltage #LowVoltage #GridInfrastructure #DataCenterEngineering #CriticalInfrastructure #SUNJ
