3000 kva oil immersed power distribution transformer Installation Standard
According to the provisions of the national standard GB50053-94 “Code for Design of 10kV and Below Substations”, outdoor oil-immersed transformers should be at least 5 meters away from any building. In accordance with the national standard “Code for Fire Protection in Building Design” GB50016 – 2006, outdoor oil-immersed transformers should be at least 6 meters away from civil buildings. Therefore, the safe distance between an open-air transformer and residential houses is at least 6 meters. The national standard also stated in 2008 that it is more appropriate to keep a distance of more than 10 meters between outdoor oil-immersed transformers and residences. Among them, it is required that high-voltage electrical facilities such as oil-immersed transformers should not be “erected” in residential communities with dense populations. This is necessary to ensure the safety of people’s lives and property!
