Engineered with precision core cutting, low-loss CRGO silicon steel, continuous foil winding, and robust enclosure protection (IP54/IP65) for extreme LATAM environmental duty.
As Argentina accelerates its grid expansion—driven by non-conventional oil and gas developments in Vaca Muerta (Neuquén Basin), massive lithium extraction projects in the high-altitude Puna region (Jujuy, Salta, and Catamarca), and utility grid upgrades under CAMMESA—the demand for factory-assembled, resilient Compact Secondary Substations (CSS) has reached an all-time high.
Engineered in accordance with IEC 62271-202 and tailored for regional integration (matching standard Argentine medium voltages of 13.2 kV, 33 kV stepping down to 380V/220V 50Hz), our CSS solutions provide complete operational safety, internal arc classification (IAC), and robust thermal management.
Equipped with SF6 Gas-Insulated Ring Main Units (RMU) or Vacuum Circuit Breakers (VCB) up to 36 kV. Features motorized operation options, SCADA readiness, and anti-reflex earthing switches.
Supports hermetically sealed oil-immersed transformers (ONAN) or Cast Resin Dry Type (F1, E2, C2 class) from 100 kVA to 3150 kVA. Designed with advanced thermal modeling to prevent hot-spots under high ambient stress.
Houses air circuit breakers (ACB), molded case circuit breakers (MCCB), automatic bus transfer, and smart power quality metering (THD monitoring) compliant with Argentine industrial codes.
Deploying electrical infrastructure in Argentina requires deep engineering adaptation to contrastive geographic terrains, extreme ambient fluctuations, and demanding industrial load profiles.
Lithium brine processing plants situated at altitudes exceeding 3,500 to 4,500 meters above sea level encounter reduced air density, which impairs dielectric insulation strength and natural cooling capabilities.
Our Customized Engineering: We apply elevation derating factors in accordance with IEC standards. CSS units built for the Argentine Puna feature extended creepage distances on MV bushings, reinforced insulation margins, and forced air cooling (AF) modifications to guarantee rated kVA output without premature thermal aging.
Shale gas fracturing sites and pump-jack installations demand rugged, rapidly deployable power units capable of enduring abrasive wind-borne sand, violent temperature swings (-10°C in winter to +45°C in summer), and heavy vibration duty.
Our Customized Engineering: Constructed with heavy-gauge corrugated steel or polyurethane sandwich panels rated to IP55, coated with ISO 12944 C5-M high-durability marine-grade paint. Substation frames undergo anti-seismic and vibration withstand reinforcement.
With Argentina's Law 27.191 mandating increased renewable contributions to the national grid, utility-scale solar projects in San Juan and wind parks in Chubut/Santa Cruz require specialized step-up substations.
Our Customized Engineering: Multi-winding solar inverter duty transformers integrated into compact kiosks handle severe harmonic distortion (K-factor rated) and repetitive cyclic loading without insulation degradation.
Metropolitan distribution utilities (such as Edenor and Edesur) require minimal-footprint secondary substations for space-constrained urban centers, commercial complexes, and data hubs.
Our Customized Engineering: Ultra-compact prefabricated concrete or metal kiosks with low noise emissions (<55 dB), internal arc protection (IAC AB 20kA 1s), and aesthetic exterior finishes tailored for municipal zoning acceptance.
Procurement engineers and EPC managers in Argentina are shifting from traditional field-erected civil substations to factory-tested, modular Compact Substations from leading Chinese manufacturers. Key market drivers include:
Integrated sourcing from China delivers savings of 30-40% compared to European equivalents, while eliminating expensive site assembly civil work and minimizing field testing risks.
Strict enforcement of grid interconnect codes demands proven short-circuit withstand capabilities, partial discharge compliance (<10 pC), and verifiable type test certification from ILAC-accredited laboratories.
Adoption of low-loss CRGO step-lap cores and dry-type cast resin units reduces no-load losses by up to 25%, directly lowering operational expenditures for private industrial operators under high energy tariffs.
Backing every compact substation shipped to South America is a state-of-the-art 103,500+ sq. ft. manufacturing center operating since 2004, staffed by over 70 qualified power engineers and high-voltage specialists.
Unlike traditional wire winding, our continuous copper and aluminum foil winding machinery eliminates mechanical transposition joints. This design distributes axial short-circuit forces uniformly across the winding, vastly enhancing mechanical strength during through-fault conditions on fragile rural distribution lines.
Utilizing top-grade cold-rolled grain-oriented (CRGO) silicon steel sourced from audited global mills, our step-lap core stacking minimizes flux leakage, reduces magnetic noise, and yields industry-leading low-loss performance matching IS 1180 Level 1/2 and IEC energy guidelines.
100% of our produced substations undergo rigorous routine testing prior to dispatch: winding resistance, voltage ratio, vector group verification, impulse withstand voltage testing, and partial discharge measurement. Factory Acceptance Testing (FAT) via live video or third-party inspection (SGS, TÜV, Bureau Veritas) is routinely facilitated for international clients.
We manage specialized heavy-lift export packaging, moisture-barrier vacuum sealing, and nitrogen-cushioned transport options to ensure equipment arrives at port facilities in Buenos Aires or Zárate in pristine operational condition.
