What may seem the simplest of things, power cables, are evolving and changing. New angles, new cable types, and new connection types are designed to ensure maximum uptime.
Hi , Data centers are moving away from under floor cooling and cabling, and in many cases to overhead cables and more advanced cooling systems. At the same time, what may seem the simplest of things, power cables, are evolving and changing as well. The reasons are quite simple. New angles, new cable types, and even new connection types are designed to ensure maximum uptime, no
cable failures and the prevention of disastrous accidental disconnects or power loss.
So what do these cables look like, and how can proper power cable usage prevent poor data center performance? Here are seven things to consider.
Cable Length Matters
In the case of power cables, the shorter the cable the better. No matter how good the power cord is, what gauge it is, or how it is insulated, aggregate power loss occurs over the length of the cord. The longer the cord, the greater the loss. In a large data center this can add up to thousands of dollars of wasted power annually.
Not only does this harm the data center’s overall power usage efficiency (PUE) but it is also harmful to the environment, increasing carbon emissions or even just diminishing efficiency in centers that rely on renewable energy sources.
Use the shortest cable you can for the application, but one that is long enough to prevent any breaks or damage caused by odd connection angles or cable stress.
Choose Your Gauge
While shorter cables are better, larger gauge cables are better than their smaller counterparts, and for good reason. First, they carry power more efficiently. Even if smaller cables might meet your needs now, moves and changes or new equipment can increase the demand on power cables.
In that case, a larger gauge cable can future-proof your data center, eliminating the need to change cables later on. Larger gauge cables run cooler, so there is no additional burden on your HVAC systems or cooling plans.

Our power cable range focuses on computer power cords, monitor power cords and server power cords typically used in data centers or enterprise networking rooms.
We ensure all computer power cords, monitor power cords and server power cords are rigorously tested to meet our exacting high quality
standards.
One of the things we talk about in cable management is how to make your data center the most efficient - which includes an effective cable labeling system. Learn how
Here's the truth, cable management can impact airflow management, and airflow should definitely inform the method, type, and execution of cable management.
