Our state-of-the-art substations are engineered to efficiently manage the transformation, distribution, transmission, measurement, and compensation of electrical energy. Featuring advanced system control, protection, and communication functions, the substation typically comprises three expertly designed compartments: the high voltage compartment (equipped with high/medium voltage switchgear like the ring main unit and gas insulated switchgear, with a maximum rated voltage of 40.5kV), the low voltage compartment, and the transformer compartment (equipped with either a three-phase oil-immersed transformer or a cast resin dry type transformer).
This substation acts as a crucial power distribution supply unit within the electrical cable power network. It offers a comprehensive power supply solution, complete with high voltage controlling, protection, conversion, and distribution capabilities. Suitable for 3 phase AC 50Hz systems with a maximum 1600KVA rated current transformer, it is widely implemented in industrial and mining enterprises, residential areas, hospitals, malls, high-rise buildings, and various other distribution systems. The compact prefabricated substation is celebrated for its efficiency, convenience, and economic value, ensuring safety and simplicity in operation.
