YB Prefabricated Substation
- Product Description
-
Product Overview
The YB series prefabricated substations are used for 6KV and 10KV ring network power supply, dual power supply, or terminal power supply systems, serving as high-voltage distribution metering, compensation control, and protection devices. Besides the transformer installed inside the prefabricated substation, the high-voltage side is equipped with four-position load switches, two-position load switches, backup protection fuses, and plug-in fuses; the low-voltage side is equipped with control electrical appliances and distribution electrical appliances according to user requirements, compensation devices, and electric energy meters. The ZGS series prefabricated substations can be used indoors or outdoors and are widely applied in industrial parks, residential communities, commercial centers, and high-rise buildings.
