Public distribution refers to the abbreviation for the installation, maintenance, and management of all local power lines, transformers, and meters to each household. In residential districts that use public transformers, the electricity meters of each household are directly installed by the power supply bureau to install mechanical meters or IC card electricity meters. The electricity price of each unit of electricity is strictly in accordance with national regulations. The bureau is responsible for installation and maintenance and management by the power supply bureau for life. There is no need to worry about improper installation or capacity of the line or transformer. In case of transformer burnout or line failure, as long as the power line is dialed 110 or 95598, the 24-hour emergency repair team of the power supply department can rush to the incident site for repair in the shortest time. Dedicated distribution. The dedicated residential district power supply department only installs a master meter in the community, and the hundreds or thousands of submeters under the master meter are not under the control of the power department. Future lines, transformers, and IC card meters installed by consumers will be purchased and installed by real estate developers in this community. Such lines, transformers, and user's sub-meters are self-contained. Specially allocated electricity prices are generally higher than public transformers. This is because the so-called losses from the electricity meter to the total meter are not borne by the power supply bureau, but are borne by the user. In the past, the use of special allocation was common. Now, with the gradual management of the power supply bureau in place, the use of special allocation should be rare.
