Prefabricated Electric Mobile Centers (PEMC) are tailor-made, factory assembled, and tested electric centers designed and manufactured to satisfy specific customer needs. The design is modular, providing a high level of flexibility to cover a wide range of applications, including:
Outdoor switching stations (up to 132kV)
Single transformer stations (up to 132kV, 20 MVA)
Multi-transformer stations
Generating electric centers
In addition, pressurized PEMCs can be provided for special applications in hazardous areas.
The primary voltage can vary up to 132kV. The secondary voltage (for transformer station PEMCs) can be either medium voltage or low voltage as per customer requirements.
The PEMC is built on a hot-dipped galvanized base frame, allowing the entire center to be lifted and carried as a single unit. Since these centers are tailor-made, their contents vary depending on specific customer needs.
A PEMC may contain some or all of the following:
Generator
Power transformer (up to 20 MVA, 132kV)
Metal-clad switchgear
Outdoor load break switches or circuit breakers
Batteries and battery chargers
Auxiliary transformers
AC/DC distribution panels
Fire detection system
Air-conditioning system
And other auxiliary equipment
