Ask an expert! What electrical appliances will be used in the new community?

If the residential area is large, it is necessary to set up an independent substation, which is generally 10kv. Provide high and low voltage distribution cabinets and corresponding equipment in the substation accordingly. Otherwise, it is directly imported from the transformer on the roadside post.

If the quality of power supply in the community is high, voltage regulators can be used. At the same time, if an emergency power supply is set, a standby transformer or diesel generator and an automatic power supply switching device are needed. Of course, you can also use the ring network cabinet to connect the electricity in the community into a ring network. The design and construction are complicated and the cost is high. But the ring network system is very reliable, so many high-end residential areas now adopt this structure.

What's left is some small equipment, such as street lamps, exhaust fans in the basement, water pumps in the landscape pool, various electrical appliances used in the building (roof lights, lighting, emergency lights, switches in the building, elevators), communication equipment, security systems, etc.

I don't know your position in this project. In fact, you can consult the electrical engineer in the project, and he will help you make a plan according to your requirements.
