Three vertical and two horizontal roads and 2500 mu of leveling were implemented in the upstream area of line 926, and the relocation of 6 km high-voltage tower was completed. Pengxi Sanfeng well is within its scope, so the high-voltage tower belongs to line 926.

Transmission tower is a towering structure, so it is also called high-voltage tower, which is the support point of overhead lines. Erecting 1 circuit on the transmission tower is a single-circuit transmission tower, and erecting 2 circuits on the transmission tower is a double-circuit transmission tower. A single loop refers to a loop with a load and a power supply. Double circuit refers to a circuit in which a load has two power supplies.
