33kV prefabricated compact substation designed for 33kV secondary distribution system from high voltage to low voltage. The main function of the compact substation is transforming high voltage from 33kV to be low voltage(415V or 380V), it depends on the electrical transformer inside of the substations.

33kV compact substation structure designed as the compact size which including high voltage switchgear, low voltage switchgear, and the electrical transformer. This specification determined the capacity of the compact substation not too big size, the electrical transformer capacity could not exceed 1600kva.
