What is a Pole Mounted Substation?
A pole mounted substation is an above-ground electrical installation mounted on utility poles, designed to step down medium voltage (typically 11kV or 33kV) to low voltage (400V/230V) for local distribution. These compact units from CONSO·CN provide a cost-effective solution for electricity distribution in both rural electrification projects and dense urban environments.
Key Advantages of Pole Mounted Substations
✔ Space-saving design - Eliminates need for ground-level installations
✔ Rapid deployment - Can be installed in hours versus days for ground stations
✔ Enhanced safety - Keeps critical equipment out of public reach
✔ Cost-effective - 40-60% lower installation costs than ground stations
✔ Vandal-resistant - Secure elevated positioning deters tampering
