Rumor Refutation：Learn theTruth and Bust the Rumors

There is no need to panic if there is a substation near your home. Firstly, the location of a substation is determined based on users’ electricity consumption and the planning and construction of the power sector. Substations have a certain coverage area, known as the power supply radius, and beyond this radius, effective power supply cannot be guaranteed.

Therefore, the construction of substations within cities cannot be arbitrarily far from users, and it is normal for them to be built near residential areas.

Secondly, although substations generate electromagnetic radiation and noise, the electric energy frequency of substations is 50 Hz, which is extremely low in the field of electromagnetic radiation and has a very small radiation range.

Therefore, even for staff who work on long-term shifts in substations, as long as they are beyond the safety distance stipulated by the national regulations, the electromagnetic radiation from the substation is less than that of mobile phones that people carry with them, so it does not affect health.

As for noise, national regulations stipulate that the noise level outside the safety distance of all substations in urban areas should not exceed 55 decibels during the daytime (equivalent to the sound of normal conversation) and 45 decibels at night (similar to the level of whispering), thus not affecting people’s daily lives.
