it can complete the transformation, distribution, transmission, measurement, compensation of electrical energy, system control and protection as well as communication functions. This substation normally comprises three compartments inside: High voltage compartment, (equiped with high/medium voltage switchgear, such as ring main unit, gas insulated switchgear, its rated volatge can reach to 40.5kv maximum)Low voltage compartment, Tranformer compartment (equipped with three phase oil immersed transformer or cast resin dry type transformer).
This substation is a very important power distribution supply unit in the electrical cable power net. it is a kind of completed set of power supply with H.V.controlling,protection and converting ,distribution. It is used in 3 phase AC 50Hz and rated current max 1600KVA transformer.It is widely used in industrial and mining enterprises, residential quarters, hospital, mall, high-rise buildings and other distribution systems. Compact prefabricated substation is one of the most effective, convenient and economical equipment and friendly solutions, safe and simple to operate a substation.
