Internal Reference:
STS-3000K-H1
The Huawei STS-3000K-H1 Smart Transformer Station is a prefabricated, pre-tested solution in a compact 20' HC container with no internal cabling needed on site. Its high-efficiency transformer and low self-consumption raise yields, while real-time detection of the transformer, LV panel and RMU with remote control of ACB and MV breaker ensure smart, reliable operation.
