This product is developed by combining the latest advanced technology from abroad with the actual domestic situation. The entire product is characterized by its small volume, easy installation and maintenance, low noise, low loss, anti-theft, strong overload capacity, and full protection. It is suitable for places such as newly-built residential areas, green belts, parks, stations, hotels, construction sites, and airports.

The ZGS11-12 series American-style pre-installed box-type substation is suitable for 10kV ring network power supply, dual power supply or terminal power supply system, as a transformer, metering, compensation control, and protection device. This product complies with the following standards: GB/T17467-1998 "Pre-installed Substations for High and Low Voltages" DL/T537-93 "Technical Conditions for Ordering 6-35KV Box-type Substations"

◆Fully insulated, fully sealed, low maintenance, and reliable to ensure personal safety;

◆Compact structure, only 1/3 to 1/5 of the height of a traditional transformer with the same capacity;

◆Can be designed with a split-box structure to avoid oil pollution inside the transformer tank;

◆The high-voltage side adopts dual-fuse full-range protection, greatly reducing costs;

◆Can be used for both ring networks and terminal systems, and the cable head can be quickly plugged and unplugged at a load current of 200A;

◆The box body adopts a honeycomb double-layer composite board, with thermal insulation and heat dissipation functions;

◆The low-voltage side is equipped with an electronic phase-loss protector. When abnormal voltage occurs in the system, the main incoming switch can be quickly disconnected;

◆The high-voltage side can be equipped with oil-immersed load switches or SF6 load switches, which can be electrically upgraded to lay a foundation for achieving distribution network automation.

◆Adopts oil-immersed S9 or more advanced S11 series transformers.
