Durable and Advanced Box-Type Substation Supplier
The Box-Type Substation features a compact, integrated design that combines medium-voltage switchgear, distribution transformers, and low-voltage switchgear into a single unit, offering a stand-alone power distribution solution from Ceho. It efficiently converts power from 11kV or 33kV medium-voltage sources to 400V/230V low-voltage outputs. Its prefabricated design also minimizes on-site installation time, making it a quick and convenient option.
Installation Precautions
Box-Type Substation installation is quick and easy, but it can't be placed anywhere.Make sure that the site you choose has a simple, horizontal concrete base or foundation that can withstand the total weight of the substation. Please confirm in advance whether the drainage measures for clear position are in place. If the oil-immersed transformer is used, the lower oil seal shall be set.
The formal installation is actually very convenient. The unit has been assembled, wired and tested in Ceho's factory. The site only needs to be placed on the foundation, connected to the incoming line, functional test and inspection. If you are not satisfied with the current setup in the future, it is possible to expand and renovate it. The easiest way is to add feeder panels at the low-voltage switchgear level. However, if it is a capacity upgrade or a medium-voltage switchgear renovation, it is recommended to contact us and Get a more targeted renovation plan.
