Why is the electricity price of property transformer expensive?

The settlement between residential areas and power grid enterprises is based on the nature of special transformers, that is, the electricity consumption of one or more transformers is only bought out at one time according to the total table, and it will be more expensive to collect the secondary distribution of property belonging to residents in residential areas.

Every household's electricity fee is paid to the property company first, and then to the power supply company by the property company. Because the property company needs to manage and maintain the "special transformer", the electricity charge will be slightly higher than the standard electricity charge.
