There are wires outside the walls of every household. Is it unsafe?

According to your description, I can answer you in two ways:

(1) If the property right of the telephone pole belongs to the power supply company, under normal circumstances, the power supply company has made detailed planning and design for the lines passing through the residential wall, which meets the national and industrial safety requirements in terms of insulation level and safety height, and there will be no hidden dangers. Please rest assured.

If you have any questions about the installation location of the power supply line, please call the 24-hour power supply service hotline 95598 to reflect, and the power supply enterprise will arrange the account manager to verify the relevant situation for you.

(2) If the telephone pole at your door is not taken over by the power supply enterprise, in this case, you need to negotiate with the owner of the telephone pole.

I hope our answer is helpful to you.
