Master Unit Substation

We have developed a more efficient 220 kV substation design. In traditional substations, the radiator is installed beside the main transformer, which occupies a large area of land.

In our design, the radiator is elevated and positioned above the side of the main transformer. The lowest point of the radiator is higher than the mid-height of the transformer. This is what we refer to as the master unit substation concept.

By optimizing the layout in this way, we free up the space beneath the radiator. The reactive power compensation device, which normally requires separate installation space, is now placed in this previously unused area.

You may be concerned about cooling performance, but there is no need to worry. Since hot air rises, positioning the radiator higher actually improves heat dissipation in this master unit substation design.
As a result, the operating environment of the equipment is improved, leading to higher stability and reliability. This design also reduces total land usage and significantly improves land utilization efficiency, delivering real value to your project.
We provide a 1-year warranty for every master unit substation. If any issue occurs, we will evaluate the problem and supply replacement parts promptly-no excuses.

We have a professional installation team through our partner company, Anhui Tianlian Power Installation Engineering Co., Ltd. The team consists of more than 50 workers, including over 20 technical staff, and is equipped with a wide range of installation machinery.
They are fully capable of handling the installation of your master unit substation without difficulty. You do not need to worry about on-site construction.
Our factory has 9 years of engineering experience behind this design. You are not only purchasing equipment-you are investing in a smarter layout that reduces land acquisition costs. That is our commitment to you.
