S-10000-11-0.48
YAWEI
YAWEI’s S-10000-11/0.48 is a high-efficiency, heavy-duty 10 MVA 11kV step down power transformer, exclusively engineered and manufactured to align fully with Ecuador national power grid technical standards and IEC 60076 international benchmarks. This 11kV to 480V 60Hz distribution transformer features a full copper winding structure, ONAN natural air cooling, and a customizable NLTC tapping range of ±8×1.25%, purpose-built to deliver stable, long-lasting performance for Ecuador’s urban and rural power distribution networks, industrial parks, commercial complexes, and renewable energy integration projects. With a specialized climate-adaptive design tailored to Ecuador’s high humidity, variable altitude conditions, and fluctuating grid load demands, this transformer supports a 25-40 year design service life, minimizing operational downtime and long-term maintenance costs for your infrastructure projects.
This step down power transformer is built to address the unique operational requirements of Ecuador’s power system, with a modular, fully customizable design that adapts to the specific needs of grid operators, power system engineers, EPC contractors, and project developers. Every unit undergoes rigorous full-load testing and quality inspection prior to delivery, ensuring full compliance with grid access requirements and reliable performance in even the most demanding operating environments.
Core design highlights include:
Rated power capacity of 10 MVA, optimized for medium-voltage power distribution applications
Step down configuration from 11kV primary voltage to 480V secondary voltage, matched to Ecuador’s 60Hz grid frequency
Full copper winding for superior conductivity, lower energy loss, and enhanced short-circuit withstand capability
NLTC (No Load Tap Changer) for flexible voltage regulation, with customizable tapping ranges to suit site-specific grid conditions
ONAN cooling system for low-noise, maintenance-free operation, ideal for both indoor and outdoor installations
We work directly with Ecuador’s power system authorities to align every design detail with local grid access rules, including voltage regulation limits, loss requirements, and fault withstand standards. This pre-compliant design streamlines your project’s grid approval process, reducing administrative delays and accelerating project commissioning.
Every unit is manufactured and tested in strict accordance with the IEC 60076 global power transformer standard, covering design, material selection, performance testing, and safety requirements. This international certification ensures consistent, reliable performance that meets global power industry best practices, with full test reports provided with every delivery.
Additional customizable standard compliance is available for specialized projects, including IEEE C57.12.00 and GB 1094 specifications.
Built with high-grade grain-oriented silicon steel core material and precision-wound full copper windings, this transformer delivers industry-leading low no-load and load loss performance. This design drastically reduces long-term grid operation energy costs, aligns with Ecuador’s energy efficiency regulations, and supports lower carbon emissions for renewable energy and sustainable infrastructure projects.
We’ve optimized the transformer’s insulation, corrosion protection, and thermal performance to withstand Ecuador’s unique environmental conditions, including high coastal humidity, variable Andean altitude conditions, and frequent lightning activity. This specialized design minimizes insulation degradation, reduces fault risk from environmental stress, and extends the transformer’s service life in harsh outdoor operating conditions.
The transformer features a reinforced winding structure, high-performance insulation system, and multi-layer safety protection design, delivering exceptional short-circuit withstand capability and overload tolerance. Every unit passes strict partial discharge, temperature rise, and dielectric strength testing prior to delivery, ensuring stable, uninterrupted power supply for critical infrastructure, industrial operations, and grid distribution networks.
We offer full customization of voltage regulation ranges, connection groups, cooling configurations, and enclosure designs to match your project’s exact specifications. The modular, pre-tested design simplifies on-site reassembly and installation, reducing on-site labor costs and shortening your project’s construction and commissioning timeline.
Optimized for grid modernization projects, delivering stable voltage regulation and low loss performance to improve grid reliability and reduce line losses for residential and commercial distribution areas.
Built to withstand the fluctuating load demands of heavy industrial operations, with enhanced short-circuit protection to ensure uninterrupted power supply for production lines, processing facilities, and industrial infrastructure.
Ideal for shopping centers, office towers, hospitals, and public infrastructure projects, with low-noise operation and high safety standards to meet commercial building codes and ensure reliable power for critical public services.
Customizable design to adapt to the variable output of renewable energy generation systems, with enhanced voltage regulation capability to support stable grid integration of solar and wind power projects across Ecuador.
