Víctor Sierra Madrigal

Víctor Sierra Madrigal is a Mexican engineer whose five-decade career has made a unique contribution to the development of electrical power systems in Mexico and Latin America. Born on September 12, 1951, he graduated as a mechanical electrical engineer from the Universidad Iberoamericana (UIA) in 1975 and completed studies in Senior Business Management at IPADE, combining technical rigor with strategic vision.

Among its most durable contributions to electrical engineering, stands out the introduction and design in Mexico of medium voltage substation output systems in HEPR 105°C cables with a high gradient, capable of operating in the presence of water at higher thermal ranges than conventional ones, ideal for critical circuits in airports, hospitals and shopping centers; compact air distribution systems with covered cables, which optimized physical space and reduced the maintenance of traditional power lines; and underground transmission of up to 400 kV with dry insulated XLP cables and longitudinally welded aluminum covers, specially adapted to the hydrogeological conditions of Mexico City.

Sierra Madrigal is founder and director of ECSA Energía Cables y Sistemas S.A. de C.V., a company specialized in the design, supply, installation and commissioning of medium and high voltage aerial, underground and submarine electrical systems. He has represented top-tier global manufacturers in Mexico and has led high-impact projects for the Federal Electricity Commission (CFE) and for PEMEX. He also chairs the Board of Directors of Sintered Alloys de México S.A. de C.V.

Its most emblematic projects include the submarine interconnection of Isla Mujeres, in the Yucatan Peninsula, and the submarine cable of Chira Island, in Costa Rica, as well as asset management systems for 230 kV high pressure oil (HPOF) cables that serve the Mexico City Metro. He has been a forerunner in Mexico of the international best practices of CIGRE —Technical Brochure 669 on mechanical forces in large conductors— and has published research at the international Jicable conferences and before the CIGRE worldwide.

Author of the Technical Manual for Medium Voltage Power Cables —published by McGraw-Hill in three editions and a reference work in Spanish-American electrical engineering—, Sierra Madrigal is also the recipient of the IEEE Centennial Medal in Mexico. He is an active member of the CIME, the IEEE and the CIGRE. His incorporation into the Pan-American Academy of Engineering as a Full Member crowns a trajectory that has positioned Mexico as a continental reference in the innovation of underground and submarine electrical transmission systems.
