High-voltage load break switches, insert-type fuses, and high-voltage current-limiting fuses are installed inside the transformer oil tank, insulated and cooled with mineral oil. It has advantages such as reasonable and compact structure, small volume, flexible installation, convenient operation, and small footprint. The combined transformer is particularly suitable for load centers in urban power grids, reducing losses and improving power supply quality.

In urban power grids of developed countries abroad, combined transformers are widely used. China is also undergoing urban and rural power grid renovations, and the ZGS13 series combined transformer is designed in accordance with the national standard GB/T10217 "Combined Transformer," undoubtedly the best distribution equipment for urban power grid renovations.
