Data center hyperscale facilities require a lot of cabling, and there are two ways to power data center IT equipment and servers: cable ducts under the floor or in overhead ceiling spaces
.
For facilities with space in the ceiling, the tray cable conduit system can be configured as an overhead power distribution system consisting of trapezoidal trays installed in a dedicated level above the racks
.
At the same time, a liquid-tight flexible conduit system can be installed under the raised floor, fixed directly in a ladder rack on the sub-floor – a common wiring system in data centers
.
Typically, data center power is distributed to multiple power distribution units through cables
.
Several types of electrical conduit are used in data centers, including flexible steel, liquid-tight jacketed conduit for computer wiring
.
Electrical conduits can also be colored to differentiate their role in the data center
.
With the rise of data center hyperscale facilities, companies face new cabling challenges, including how to improve public safety and speed up the installation process to reduce costs and get facilities up and running faster
.
The rise of polyurethane pipes
The rise of polyurethane pipesIn terms of safety, electrical hazards have the potential to injure employees
.
For wiring and wire conduit inside data centers, choosing the wrong product can lead to the accidental release of toxic gases in the event of a fire
.
Choosing the right wire can reduce the risk of potentially toxic fumes and reduce the spread of fire
.
As a result, data centers around the world are turning to pipes with polyurethane jackets
.
Polyurethane pipes are inherently safer because they are resistant to hydrocarbons, moderate chemicals, and grease
.
These pipes are a low fire hazard solution because they emit small amounts of non-toxic fumes, have low flame spread, are self-extinguishing and do not emit halogens
.
Known as zero-halogen flexible electrical conduits, these replace PVC products and eliminate the release of toxic halogen gases such as hydrogen chloride, hydrogen fluoride and hydrogen bromide gases and other deadly combustion products
.
Due to the benefits of zero-halogen electrical conduit, many data centers in Europe are beginning to phase out other conduits in favor of polyurethane, and companies in the United States are also trending toward polyurethane
.
Data Center Prefabricated Piping
Data Center Prefabricated PipingThe electrical system prefabrication method has re-emerged in the design of electrical conduit spaces
.
While the prefab approach has been around for decades, contractors are again turning to prefab due to persistent labor shortages and difficulty finding dedicated resources to cut products to fit data center needs
.
The use of prefabricated conduit in the data center can reduce the time spent installing conduit on site, thereby increasing productivity
.
Additionally, prefabricated piping in the data center reduces material and labor costs, shortens project schedules and improves safety
.
A dedicated prefab department creates prefab electrical whips that allow contractors to take advantage of these advantages
.
The installation of prefabricated pipes also eliminates the need for data centers to do it themselves, or hire people to service them
.
On the installation side, the trend in data center cabling is moving towards the use of high-quality prefabricated electrical distribution assembly drawers in a variety of colors and jacket options; on the safety side, the use of jacketed zero-halogen polyurethane conduit also prevents potential A catastrophic event occurs
