How is the trunk-type power supply system powered by the industrial and mining enterprises?

The wiring configuration of the trunk power supply system for dual-end power supply in industrial and mining enterprises is illustrated in Figures 1-7. This method is cost-effective, requiring lower initial investment. However, it has limited adaptability to automation and can be relatively complex to implement. It is suitable for secondary load applications. If there is a tie line on the low-voltage side, it may even be used for primary load requirements. The design allows for flexibility in power distribution, making it an efficient solution for certain types of facilities. Additionally, this configuration can help improve system reliability by providing alternative power paths during outages or maintenance. It's important to carefully evaluate the specific needs of the facility before implementing this type of wiring setup.
