How to weed outside the state grid substation?

Understand whether there is live equipment in the work area and work scope.

Don't weed outside the scope of work. If the weeding area is charged, do not use long tools to avoid electric shock. If the weeding area is electrified, please keep a sufficient safe distance from the electrified equipment. The general principle is that the voltage of 220kV should be kept away from the voltages of 3m, 1 10kV, 1.5m, 35kV and 10kV, and the distance should be kept at least 70cm.

Substation is a place to change voltage. In order to transport the electric energy of power plant to a long distance, it is necessary to raise the voltage and turn it into high-voltage electricity, and then reduce the voltage as needed when it reaches the vicinity of users. This work of raising and lowering the voltage depends on the substation.
