INDUSTRIAS ECTRICOL S.A.S. participated in the electrical supply of an energy transformation center for the cargo terminal of the Jose Maria Córdoba International Airport in the city of Rionegro, Antioquia. A provisional mobile work unit was temporarily installed to supply energy to cold rooms with a total power of 630 kVA, which houses the substation elements such as the dry transformer, medium-voltage protections, low-voltage switchboard and interconnections. The purpose of the energy substation service is to avoid electrical risk since its metal enclosure protects the equipment and the lives of people who may be around it, is easy to move and is used outdoors for large projects or activities, as in this case. Our goal is to always provide security to our customers and reliably provide energisation of projects.
