Box type transformer: equivalent to combined (box type) substation.(American type transformer)
The box type transformer is of frame structure, welded with section steel, and coated with aluminum alloy plate and special paint layer to make it have strong mechanical properties, weather resistance and corrosion resistance. When the combined (box type) substation is an integral structure, the box is divided into three relatively independent chambers with steel plates, namely, high-voltage chamber, transformer chamber and low-voltage chamber. The lighting of each room will be automatically shut down with the opening of the door.
The top of the combined (box type) substation is provided with a thermal insulation layer. In high temperature and cold regions, the temperature in the box is easy to accumulate and change and condense, so the thermal insulation layer around the box can be added. In order to stabilize the temperature in the box, the transformer room and low-voltage room are equipped with automatic temperature control devices.
Overview of the product
This product is absorbing the latest foreign advanced technology, combined with the actual situation of the domestic research and development, the whole product has a small size, easy installation and maintenance, low noise, low loss, anti-theft, overload capacity, full protection and so on.

ZGS13-H series American pre-installed box-type substation is suitable for 10kV ring network power supply, dual power supply or terminal power supply system, as a substation, metering, compensation control and protection devices.
This product complies with the following standards: GB/T17467-1998 'High-voltage and low-voltage pre-assembled substation', DL/T537-93 '6-35kV box-type substation ordering technical conditions'.
Model Meaning
Functions and features
1.Fully insulated, fully sealed, maintenance-free, and reliably guaranteeing personal safety;
2. Compact structure, the volume is only 1/3-1/5 of the same capacity of the European transformer, low height;
3. It can adopt split-box structure to avoid the pollution of oil in the transformer oil tank;
4. The high-voltage side adopts double-fuse full-range protection, which greatly reduces the cost:
5. It can be used for ring network as well as terminal, and the cable head can be plugged and unplugged urgently at 200A load current;
6.The box adopts honeycomb double sandwich composite board, which has the function of temperature insulation and heat dissipation;
7. The low-voltage side is equipped with an electronic phase-loss protector, which can quickly disconnect the main inlet switch when abnormal voltage occurs in the system;
8. Oil-immersed load switch or SF6 load switch on the high-voltage side can be upgraded electrically, laying the foundation for realising distribution network automation.
9.Adopting oil-immersed S9 or S11 series transformers with better performance.
