You are working on the design of a new facility. The electrical riser of the building with high current power is located close to the area where…

To reduce Electromagnetic Fields (EMF) emanating from the electrical riser near sensitive IT

equipment, three-phase power cabling in a combined cable (such as XLPE) is effective. Combined

cabling helps reduce EMF by keeping the conductors tightly packed, which minimizes magnetic fields

generated by current flow. Cables like XLPE (cross-linked polyethylene) also offer better insulation,

which helps mitigate EMF interference with nearby IT equipment.

Detailed Explanation:

Using a combined three-phase cable reduces EMF because the magnetic fields generated by each

phase tend to cancel each other out when in close proximity. This arrangement helps reduce the

overall magnetic field strength. In addition, XLPE and similar materials provide good insulation,

making them a preferred choice for reducing EMF emissions around sensitive equipment.

EPI Data Center Specialist Reference:

EPI data center best practices recommend mitigating EMF interference through combined cabling

arrangements, especially near areas where sensitive IT equipment is located. Reducing EMF is crucial

to maintaining equipment reliability and ensuring compliance with safety standards.
