Engineered to meet national ABNT standards and satisfy heavy-duty electrical demands in the power transmission grids of Brazil.
Brazil is currently executing one of the most comprehensive power grid expansions in South America. Driven by huge renewable energy complexes—such as massive solar fields in Minas Gerais and high-capacity wind farms in Rio Grande do Norte—the demand for ultra-high voltage (UHV) and extra-high voltage (EHV) step-up transformers is rising exponentially.
Heavy electrical equipment manufacturers like WEG, Alstom, and local transformer repair engineering firms face the pressure of upgrading local systems to guarantee grid stability. Paper Covered Flat Wires, also known as Kraft paper insulated rectangular wires, are the foundational materials inside these gigantic power transformers and distribution units. The rectangular profile ensures maximum copper or aluminum cross-sectional density within minimum space, significantly improving the slot fill factor and lowering winding losses.
In power grids operating under intense thermal fluctuations—common in tropical regions of Brazil—minimizing heat dissipation is a matter of equipment survival. Rectangular magnet wires, compared to round wires, provide a significantly higher surface area, allowing heat to escape efficiently through the oil ducts of transformer modules. This geometric superiority enables designers to build compact, efficient, and robust installations that conform to ABNT standard ratings.
We source premium, chemical-free insulation paper to produce our wrapped flat conductors. Depending on your operational requirements, the choice of wrapping includes:
With global raw material fluctuations, optimizing costs is critical. Paper covered flat aluminum wires serve as a highly economical, lightweight solution for rural electrification and distribution transformers in Rio de Janeiro or Bahia. Conversely, paper wrapped flat copper wire remains indispensable in high-current density power transformers, generators, and large motors where space limitations restrict structural adjustments.
As transmission voltages transition toward 500kV and higher across the Brazilian Interconnected Power Grid (SIN), minimizing eddy current losses becomes paramount. Our Continuously Transposed Conductor (CTC) lines solve this issue by transposing individual enameled flat wires, allowing Brazilian utility engineers to build high-efficiency power networks with minimized grid loss values.
Unmatched supply capacity, advanced processing machinery, and strict quality control matrices that secure your operations.
