Substations can be divided into: hub substations, terminal substations; step-up substations, step-down substations; power system substations, industrial and mining substations, railway substations (27.5KV, 50HZ); 1000KV, 750KV, 500KV, 330KV, 220KV, 110KV, 66KV , 35KV, 10KV, 6.3KV and other voltage grade substations; 10KV substations; box-type substations.

Use angle steel or tube steel as the tower column material, the wind load coefficient is small, the wind resistance is strong, the tower column is connected by the outer flange, the bolt is tensioned, it is not easy to be damaged, and the maintenance cost is reduced. Small size, small area, saving land resources, convenient site selection, light weight of the tower body, convenient transportation and installation, and short construction period. Comply with steel structure design code and tower mast design code, structure. Effective use period: more than 50 years.

Performance characteristics:
1. Tower verticality: 1%‰

2. Design wind speed: 25m/s-35m/s

3, grounding resistance: ≤4Ω

4, the tower is allowed to wrap ice: 5-6MM

5. Anti-loss ability: Wind 10

6. Anti-corrosion treatment: hot zinc anti-corrosion treatment/cold zinc anti-corrosion/painting
