What is the safe distance between a substation and residential buildings

The safe distance between Substations and residential buildings is clearly stipulated by national regulations, with the core basis being the voltage level. The specific standards are as follows:

10KV-35kv Substation:
The distance from the front (facing the residential side) must be ≥ 12 meters.
The distance from the side (non front) must be ≥ 8 meters. ‌‌

Substations above 35KV:
The front distance should be ≥ 15 meters.
The lateral distance should be ≥ 12 meters. ‌‌

Box type substation (prefabricated small substation):
The distance should be ≥ 5 meters, suitable for low voltage scenarios. ‌‌

Please note that as the equipment at each substation may vary, the specific distance needs to be determined based on the actual situation of the transformer. When purchasing a house or installing a transformer, safety distance should be fully considered to avoid potential safety hazards. At the same time, if any violation of safety distance regulations is found, it should be reported to relevant departments in a timely manner to ensure the safety of oneself and others.
Overall, maintaining a safe distance between transformers and buildings is crucial. This not only reduces the potential impact of noise, electrical radiation, and explosions caused by transformers on residents' lives, but also complies with national laws and regulations.
