Premium 3-phase transformers optimized for grid integration, smart load regulation, and maximum efficiency.
A technical overview of the local distribution framework governed by the Administration Nacional de Electricidad (ANDE).
Paraguay presents a unique electrical landscape. As a global leader in clean energy generation—driven entirely by gargantuan hydroelectric power generation facilities like Itaipu and Yacyretá—the country boasts a massive surplus of green electrical capacity. However, translating this high-voltage generation into reliable local power requires a highly resilient, modern distribution network. The national utility company, ANDE (Administración Nacional de Electricidad), oversees the installation of electrical hardware. Medium-voltage (MV) distribution in Paraguay operates predominantly at 23 kV with a utility frequency of 50 Hz, transitioning down to secondary low-voltage levels of 380V (three-phase) and 220V (single-phase).
For industrial operators, commercial complexes, and developers looking to establish operations in Paraguay, acquiring three-phase distribution transformers that match ANDE's exact operational envelope is critical. Henan Pirooz Power Co., Ltd. custom-designs and manufactures three-phase oil-immersed and dry-type transformers specifically tailored to withstand the high ambient temperatures, high humidity, and cyclic loads typical of Paraguay’s subtropical zones (particularly in industrial sectors like Alto Paraná, Central Department, and the Chaco region).

When engineering for the Paraguay market, typical commercial transformers fail due to premature thermal aging. Our specialized insulation solutions, including Class A and Class H oil-impregnated or cast-resin systems, are rated to operate safely even at ambient temperatures exceeding 40°C. Lowering no-load losses (Po) and load losses (Pk) is vital not only to reduce operating expenses but to comply with the modern energy efficiency mandates pushed by the national regulator.

Ensuring timely delivery and operational security from the factory floor to regional inland ports.
As a landlocked nation, importing heavy capital electrical equipment into Paraguay requires dedicated logistical coordination. Henan Pirooz Power Co., Ltd. has established robust supply-chain networks. Transshipment is typically managed via deepwater ocean vessels to regional hub ports in Montevideo (Uruguay) or Buenos Aires (Argentina), where the equipment is safely transferred onto inland container barges. These barges navigate the Paraná-Paraguay waterway directly to major inland ports like Puerto Villeta, Puerto Caacupemí, or Asunción.
Our global shipping team manages all aspects of ocean freight documentation, marine transport insurance, and transit tracking. To simplify import clearance under local customs guidelines (DNA - Dirección Nacional de Aduanas), we provide comprehensive test reports, certified origin verification, and dimensional blueprints matching the specifications requested by engineering contractors.
Upon arrival, our localized engineering support ensures smooth installation. We provide commissioning oversight, transformer oil purification guidelines, field testing advice, and rapid supply of critical spare parts (such as high-voltage bushings, gaskets, tap changers, and silica gel breathers) to prevent long periods of down-time.
Direct technical answers addressing specific transformer installation and integration challenges in Paraguay.
ANDE (Administración Nacional de Electricidad) uses a primary medium-voltage distribution network operating at 23 kV (50 Hz). Standard step-down transformers must reduce this primary voltage to either 380V (three-phase phase-to-phase) or 220V (single-phase phase-to-neutral) to feed industrial machinery and commercial building distribution panels.
We apply high-grade mineral oils or synthetic esters with superior thermal stability. Core cooling ducts are dimensioned using advanced thermal modeling to ensure natural oil circulation (ONAN). Furthermore, the core-coil assembly uses Class H and Class A insulation materials to prevent degradation during prolonged summer peaks exceeding 40°C.
Yes. Our SCB13 and SCB14 series cast-resin dry-type transformers undergo vacuum-pressure encapsulation. The epoxy resin completely seals the windings, preventing moisture absorption. They are certified for environmental class E2 (severe condensation and humidity protection), making them highly suitable for the tropical river valleys of eastern Paraguay.
The S20 series features advanced grain-oriented silicon steel laminations with multi-step mitred joints, resulting in lower no-load loss by approximately 20-30% and load losses by 10-15% compared to the older S11 models. This translates to lower continuous energy dissipation and lower total cost of ownership (TCO) for grid operators.
Yes. For border zones or multinational factories in Free Trade Zones, we design dual-frequency cores. Operating a 60Hz transformer on a 50Hz grid requires custom coil configurations to prevent core saturation and excessive heat build-up. We guarantee precise electrical performance across both profiles.
We load the cargo into standard or open-top shipping containers. Ships navigate to the Montevideo or Buenos Aires ocean port terminals, where cargo is transferred to river container barges that ascend the Paraguay River to the inland ports of Asunción or Villeta, completing transit safely and securely.
