The electromagnetic radiation of the strong electric well is mainly the power frequency magnetic field radiation, if the current exceeds 100a amperes above, will produce strong magnetic field radiation, a large number of high-rise area magnetic field test case analysis that: a power distribution room, Wells of the place, in the peak period will produce up to ten micro-Tesla strong magnetic field radiation, because people do not know much about the magnetic field radiation, but the harm is the most serious electromagnetic radiation, far more than the base station The harm of the human body.
Is that right?
Second, the cable wells or tunnels formed by concrete become the second gate for shielding electromagnetic radiation. I am doing industrial electricity, tell you that my main control room office in 110KV substation near the main transformer less than 50 meters away, 110kV GIS high voltage distribution device is also nearby, with the counter test workplace electromagnetic radiation value only Less than 10% less than other office buildings away from substations. Not to mention your district civil buildings up to 380 of the highest AC! So that the strength of electromagnetic wells in the electromagnetic radiation serious harm to people this is simply nonsense.
If simply from the data and the impact is concerned, of course, your home wires near the electrical equipment between the electromagnetic radiation to be larger. For example, a 6KV high voltage cable from my house about 1 meter from the distance through the balcony after the electromagnetic field strength and crosstalk value of my refrigerator near the refrigerator near the strong electromagnetic field. It should be noted that this level of electromagnetic field on the basic health of the basic no effect, not to mention people are active, as your home opposite the electric door, but do not need to consider.
If you want to ask the wells on the damage to the building staff, tell you - almost negligible. First, the power cable and signal cable is laid in the metal bridge inside, the bridge itself has a strong electromagnetic shielding effect.
