Sealed hermetic tank design preventing moisture ingress under coastal and desert saline humidity.
Ultra-low no-load loss and high thermal stability built for continuous heavy industrial mining cycles.
Equipped with automated on-load tap changers for seamless grid balancing amid intermittent solar feeds.
Self-extinguishing, maintenance-friendly design ideal for confined underground mine chambers and urban substations.
Chile stands as one of Latin America's most dynamic energy corridors, characterized by its unified Sistema Eléctrico Nacional (SEN) that spans over 3,100 kilometers from Arica in the northern desert down to Chiloé in the south. As the country accelerates its National Decarbonization Plan and expands its high-voltage transmission lines (including 110kV, 220kV, and 500kV trunk corridors), electrical utilities, engineering EPCs, and mining conglomerates demand next-generation instrumentation transformers.
Capacitive Potential Transformers (CPTs / CVTs) play an indispensable dual role in modern Chilean electrical networks: providing high-accuracy voltage step-down for metering and protective relaying, while simultaneously serving as coupling capacitors for high-frequency Power Line Carrier (PLC) telecommunications and digital substation protocols.
Due to the vast geographical distances between transmission hubs across Chile's desert and mountainous terrain, CVTs are heavily utilized for teleprotection and communication signals over transmission lines. Our easy-maintainable capacitive voltage transformers feature integrated low-loss carrier accessories (drain coils, grounding switches, and surge arresters) configured for immediate terminal integration.
Equipped with stainless steel expansion bellows that absorb thermal volume changes without exposing dielectric fluid to ambient air, moisture, or desert sand particulate. Visual indicators allow maintenance teams to verify oil health instantly from ground level.
High-efficiency passive damping circuits eliminate subharmonic and fundamental ferroresonance oscillations caused by circuit breaker switching or transient grid faults across long Chilean transmission corridors.
Configured for online tan δ (dielectric dissipation factor) sensing, capacitance drift monitoring, and direct interface with IEC 61850 process bus merging units for smart asset health analytics.
High-grade silicone composite or glazed porcelain insulators with extended creepage distances (up to 31mm/kV or higher) to resist intense ultraviolet radiation and high contamination levels common in northern Chile.
The lower base electromagnetic unit features standardized terminal junction boxes, test taps for easy power factor testing, and modular replacement components, drastically cutting Mean Time to Repair (MTTR).
Finite element analyzed (FEA) base structures and high-strength aluminum/cast steel flanges resist high-magnitude ground acceleration, meeting Chile's strict earthquake safety guidelines.
Mining extraction facilities like open pits, SX-EW plants, and underground crushing circuits operate around the clock with huge inductive loads. Easy-maintainable CPTs and robust distribution transformers supply exact voltage signals to differential protection relays, safeguarding heavy ball mills, SAG mills, and overland conveyors from costly voltage sags or phase faults.
The Atacama Desert boasts the world's highest solar irradiance. Utility-scale PV stations connected to 220kV/500kV booster substations utilize our capacitive potential transformers for tariff revenue metering (Accuracy Class 0.2 / 0.2S) and high-speed inverter grid synchronization under rapid cloud-induced ramp-rate changes.
Metropolitan feeders and manufacturing estates require uninterrupted power quality. Our oil-immersed and cast resin transformers, paired with precision measurement units, provide harmonic attenuation, low audible noise, and on-load tap regulation to stabilize urban distribution networks.
Subjected to high wind shear, low ambient temperatures, and maritime coastal moisture, our cold-resistant dry-type and sealed oil-immersed transformers ensure zero oil leakage and minimal maintenance overhead in remote southern wind generation clusters.
