In telecommunications construction, the distribution equipment room is indispensable. Of course, many people also wonder just how significant the radiation from such a room is and what the installation standards for these rooms actually entail. Today, we’ll take a close look at these issues together. 
Distribution System
Is there significant radiation in the distribution room?
Expert Clarification: No Significant Impact
Environmental experts state that, from a scientific standpoint, distribution rooms do generate some electromagnetic radiation when producing alternating current; however, the radiation levels are very low and well within national regulatory limits—likely only slightly higher than the radiation emitted by common household appliances such as refrigerators and computers. Moreover, the power-supply equipment in distribution rooms is enclosed by walls, and ordinary brick walls can effectively block most of this radiation. Therefore, the radiation from distribution rooms poses no significant health risk to humans, a conclusion that has never been supported by international epidemiological studies.
However, environmental experts point out that although distribution rooms do not emit radiation pollution, the humming noise they produce can be quite disturbing. “The noise from distribution rooms is low-frequency and highly penetrating, yet it typically does not exceed the limits set by environmental monitoring standards.”

What are the installation specifications for distribution equipment rooms?
(1) Hosts, storage devices, and server cabinets should be arranged in designated zones. For hosts, storage devices, server cabinets, as well as UPS units and air-conditioning equipment, maintenance clearance shall be provided in accordance with the manufacturers’ specifications; overlapping of maintenance clearances between adjacent equipment is permitted.
(2) Reasonably plan the phased entry of equipment into the computer room and the relative positioning of reserved expansion equipment, ensuring compliance with the computer system’s process flow while facilitating the future delivery, placement, and cabling of additional equipment.
(3) When installing high-heat-generating servers such as the IBM 690 and 670 in server cabinets, the clear distance between the fronts of adjacent cabinets shall not be less than 2.1 meters to prevent excessive thermal density that could impair equipment cooling.
(4) For server rooms with a large number of devices, it is recommended to adopt a row-end cabinet configuration, whereby structured cabling cables are aggregated at the row-end cabinets rather than the core cabinet, thereby reducing the consumption of twisted-pair and fiber-optic cables.
That concludes our discussion on whether distribution rooms generate significant radiation and on the relevant installation standards for such facilities. We hope this information proves helpful to you.
