Product Overview
The S11 series oil-immersed transformers, purpose-built to fulfill the demands of energy efficiency, silent operation, and robust reliability. Tailored for versatile applications, these transformers thrive in urban-rural power networks, industrial parks, and a spectrum of complex power environments where consistent performance is non-negotiable.
Incorporating cutting-edge technologies and premium-grade materials, the S11 offers outstanding electrical performance. Each unit is meticulously engineered to comply with the rigorous standards of modern power grids, integrating strict energy-saving and eco-friendly protocols. From their optimized core designs to advanced insulation systems, these transformers minimize energy dissipation while ensuring stable operation, making them a cornerstone for critical infrastructure projects that prioritize both performance and sustainability.Model Definition
Features
● Voltage level: 10～35/0.4kV.
● Capacity: 30～3150kVA.
● Low Losses: The core is constructed from high-quality cold-rolled silicon steel laminations, significantly reducing no-load losses and magnetizing current.
● Quiet Operation: The transformer core is tightly bound to ensure structural integrity, minimizing operational noise.
● Fully Sealed Design: A hermetic enclosure extends service life and eliminates maintenance needs. The corrugated tank design accommodates oil expansion through elastic deformation, isolating the oil from ambient air.
● High Short-Circuit Withstand: Advanced manufacturing processes ensure the transformer can endure short-circuit currents without thermal or mechanical damage.
● Environmental & Safety Compliance: The tank and oil reservoir undergo pressure testing to prevent leaks under normal operation.
● Efficient Cooling: The transformer oil’s superior thermal conductivity absorbs and transfers heat via natural convection or forced circulation, maintaining optimal operating temperatures.
Range of application
Suitable for urban and rural power grid construction and renovation projects, as well as other distribution engineering projects, such as high-rise buildings, densely populated residential areas, important government agencies, airports, subways, stations, ports, petrochemicals, metallurgical mining, power plants, and places that require fire and explosion prevention.
