Audited Supplier
The YB27-12 American prefabricated box-type substation (also known as the American box substation and abbreviated as the American substation) is developed by absorbing advanced foreign technologies and combining with the actual domestic situation.It is applicable to 12KV ring network power supply, dual-power supply or terminal power supply systems, serving as a substation,power distribution, metering, compensation,control and protection device. This product has the characteristics of small size, simple installation and maintenance,low noise,low loss, anti-theft, strong overload capacity and comprehensive protection. It can be placed either indoors or outdoors and is suitable for new residential areas, green belts,parks,stations,wharves, hotels, construction sites, airports and other places. Inside the American substation, in addition to the transformer, on the high-voltage side, there are four-position load switches,two-position load switches, backup protection fuses and plug-in fuses.On the low-voltage side,control electrical appliances,power distribution electrical appliances,compensation devices and metering instruments can be installed according to users' requirements. Transformer oil is used as the insulating and arc-extinguishing medium.The box body of this product is fully assembled.
