High Voltage 220KV Transformer Substation Structures
Function of Substation:
-----------------------------------
Electric substation refers to the place where voltage and current are transformed, electric energy is received and distributed in the power system.
The main function of substation is to connect the power grids with different voltage levels, and complete the task of power transmission and distribution through transmission lines.
Generally speaking,The power generated by the power plant is boosted to the power grid through the step-up substation. After the power grid sends the power to the destination, it is depressurized and distributed to users through the step-down station.

Quick details:
Transformer substation steel structure is the important component for power transmission. The galvanized steel is the most common type raw material.
Usually a substation structure consits of three parts: dead-end structures(H frame and A frame), static poles and bus supports/equipment stands.
