Designed in collaboration with Comision Federal de Electricidad (CFE), Mexico’s national utility company, for urban applications, the transformers would be deployed by CFE to help modernize electrical substations across Mexico City and its metropolitan area.
The new transformers make use of less-flammable synthetic ester liquid as a coolant, unlike traditional mineral oil, and dielectric insulator instead of traditional oil, in order to reduce the risk of potential transformer fire and contamination concerns.
CFE technical manager Federico Ibarra said: "Fires in transformers can be highly dangerous and devastating to areas in close proximity to the substation.
"Our decision to implement Prolec-GE’s new transformers was made with this in mind.
"Not only will the units reduce the risk of significant fires at our electrical substations, they also will reduce our potential environmental impact and help to modernize our electrical infrastructure."
Prolec-GE and CFE partners are currently implementing a project which covers installation of more than 50 power transformers, and will be rolled out in five stages.
As part of current phase of the project, Prolec-GE is providing four 36/48/60 MVA, 230/23/15 kV, high-voltage on-load tap-changer (OLTC) power transformers as well as four 18/24/30-MVA, 85/23 kV, low-voltage OLTC power transformers and three 18/24/30 MVA, 115/85/23 kV, low-voltage OLTC transformers.
CFE is currently installing the new Prolec-GE power transformers which are planned to be commissioned by the end of 2015.
