Transformer
Pedestal
Pad-mounted three-phase transformers, installed outdoors, mounted on concrete bases. Developed for applications where physical space is limited, such as shopping centers, malls, schools, plazas, tourist areas, hospitals, wind and solar parks, small and medium-sized industries, under the concept of compact substations, in accordance with ABNT NBR, IEC, ANSI / IEEE standards, and other specific standards of all utilities and/or clients. Some advantages: Safety, cost-effectiveness, compactness, protection, environmental friendliness, and reliability.
Power ratings from 45kVA to 10,000kVA.
-
AT: Class 7.2kV, 15kV, 25kV, and 36kV
-
BT: Class 1.2kV, 7.2kV, and 15kV
-
Installation: Cabins or Substations / Indoor/Outdoor environments, normal or aggressive.
