Tailored to withstand seismic zones, high altitudes exceeding 4,000 meters in the Andes, and heavy non-linear harmonic loads in mining electrowinning facilities.
Chile stands as the world's leading copper producer and a vanguard in Latin America's clean energy transition. Spanning over 4,300 kilometers along the Pacific Rim, the country's unique geographical and climatic topography presents distinct electrical challenges. From the arid hyper-radiance of the Atacama Desert to the high-altitude Andean plateaus and the windy plains of Magallanes, electrical equipment must deliver unwavering reliability under extreme operational stress.
As Chile continues executing its ambitious Plan de Descarbonización (Decarbonization Plan to eliminate coal by 2030 and achieve carbon neutrality by 2050), the expansion of the Sistema Eléctrico Nacional (SEN) demands high-capacity, low-loss oil-immersed transformers capable of handling bi-directional energy flows, intermittent renewable feeds, and severe harmonic distortions from massive mining rectifiers.
Standard commercial transformers frequently fall short when deployed across Chilean industrial sites. Oil-immersed transformers supplied to this market must incorporate stringent design considerations:
Heavy-duty ZSG/ZHS rectifier transformers designed for high-current copper and lithium solvent extraction-electrowinning (SX-EW) circuits, engineered with specialized phase-shifting to suppress 12-pulse and 24-pulse harmonic heating.
33kV / 35kV to 110kV/220kV generator step-up transformers optimized for utility-scale Atacama PV farms and coastal wind parks, providing robust electrostatic shielding against inverter high-frequency switching transients.
Continuous duty, ester-filled or mineral oil transformers feeding massive reverse-osmosis coastal desalination plants and emerging megawatt-scale PEM electrolyzer pilot facilities in Antofagasta and Punta Arenas.
Combining high-permeability cold-rolled grain-oriented (CRGO) silicon steel cores, intelligent IoT condition monitoring, and biodegradable dielectric fluids to maximize asset life and energy efficiency.
With strict environmental regulations enacted by the Chilean Ministry of the Environment (MMA) and the Superintendencia de Electricidad y Combustibles (SEC), heavy industries are increasingly adopting natural and synthetic ester fluids. These fluids offer high fire points (>300°C), eliminating explosion hazards in underground mining shafts while offering 100% biodegradability in sensitive Andean ecological zones.
Our oil-immersed transformers can be customized with high-grade synthetic or natural ester oils, ensuring extended insulation life, superior moisture absorption capacity, and compliance with strict environmental impact assessments (EIA).
Given that substations in Northern Chile are often located hundreds of kilometers away from urban centers, remote intelligence is mandatory. Our transformers integrate optical fiber temperature sensors directly embedded in high-voltage windings, online Dissolved Gas Analysis (DGA) monitors, moisture-in-oil transmitters, and automated OLTC health diagnostic units linked directly to central SCADA systems.

Comprehensive transformer solutions for distribution networks, transmission substations, industrial power conversion, and earthing protection.
Essential considerations when purchasing oil-immersed transformers for installation in Chilean substations, mining facilities, and renewable energy plants.
Chile is subject to frequent high-magnitude seismic events. All immersed transformers must come with comprehensive finite element analysis (FEA) reports verifying that the transformer tank base anchors, radiator supports, and conservator mountings withstand dynamic horizontal and vertical accelerations compliant with IEEE 693 High Performance Level.
For mining facilities in the Antofagasta, Calama, and Atacama regions operating between 2,500m and 4,500m above sea level, air density decreases significantly. This reduces natural convective cooling and air dielectric breakdown strength. Our engineering team calculates exact derating coefficients, increasing radiator cooling surface areas and enlarging phase-to-phase and phase-to-ground bushing clearances.
Large cycloconverters, variable frequency drives (VFDs) for mining crushers, and SCR rectifiers for copper electrorefining inject heavy 5th, 7th, 11th, and 13th order harmonics. Our oil-immersed units employ transposed conductors, electrostatic ground shields between primary and secondary windings, and specialized core geometries that prevent localized hotspot overheating under elevated K-factor loads.
All units are engineered to meet the regulatory requirements established by the Coordinador Eléctrico Nacional (CEN) and the Superintendencia de Electricidad y Combustibles (SEC), facilitating rapid grid connection approvals and seamless commissioning on the Chilean interconnected transmission network.
