Mobile Transformer Substation

Mobile Transformer Substation 
Prefabricated Electric Mobile Centers (PEMC) are tailor made, factory assembled and tested electric centers designed and manufactured to satisfy every specific customer needs. The design is a modular one, which provides a high level of flexibility in order to cover a wide range of applications. That includes outdoor switching stations (up to 132kV), single transformer stations (up to 132kV, 20 MVA), multi-transformer stations or generating electric centers. In addition, a special arrangement for pressurized PEMCs can be provided for special applications in hazardous areas. The primary voltage can vary up to 132kV. However, the secondary voltage (for transformer station PEMCs) can be a medium voltage or a low voltage as per the customer requirements. Prefabricated electric center is built on a hot-dipped galvanized base frame in such a way that the whole center can be liftted and carried as a single unit. Since these centers are tailor made, their contents vary depending on the specific needs of a customer. For example, a PEMC might contain some or all of the following: generator, transformer, metalclad switchgears, outdoor load bread switches or breakers, batteries and battery chargers, auxiliary transformers, AC/DC distribution panels, fire detection systems, air-conditioning systems, and many other equipments.
