Product Overview
S20 Series three-phase oil-Immersed transformers as the next-generation energy-efficient power equipment, it achieves a breakthrough in energy efficiency with 30% lower no-load losses and 25% reduced load losses compared to the S13 series. Featuring a core constructed from high-permeability grain-oriented silicon steel laminations with stepped-lap joints, the design minimizes hysteresis and eddy current losses, resulting in a 40% reduction in no-load current.
The fully sealed corrugated tank design automatically compensates for oil volume fluctuations caused by temperature changes through elastic deformation of the corrugated sheets. This hermetic structure eliminates the need for an oil conservator, enabling maintenance-free operation and extending service life to over 35 yearsModel Definition
Features
● Voltage level: 10～35/0.4kV.
● Capacity: 30～3150kVA.
● High-Efficiency Energy Optimization: Leveraging next-generation energy-saving technologies, this design significantly reduces no-load and load losses compared to traditional models, meeting industry-leading efficiency standards. It substantially cuts long-term operational energy costs, making it ideal for high-load power applications with strict energy consumption control requirements.
● Low-Magnetic Loss Core Technology: Utilizes high-permeability grain-oriented silicon steel laminations with stepped-lap joint technology to minimize hysteresis loss and no-load current, reducing core heating and excitation energy loss.
● Fully Sealed Maintenance-Free Design: The corrugated tank automatically compensates for oil volume fluctuations through elastic deformation, isolating oil from air contact. This eliminates the need for an oil conservator or regular oil changes.
● Low-Noise Eco-Friendly Operation: Incorporates noise-dampening lamination technology and low-noise fans, ensuring minimal no-load and load noise levels that comply with requirements for noise-sensitive areas like urban residential zones and hospitals.
● Compact Space-Saving Structure: Features a minimized cabinet volume and footprint, suitable for space-constrained environments such as high-rise building switchrooms and subway traction substations.
● Full-Process Sealing Assurance: The tank undergoes leak testing to ensure zero leakage risk throughout the product’s lifecycle.
Range of application
Widely applicable to high-rise buildings, commercial centers, subways, airports, railway stations, industrial and mining enterprises, drilling platforms, and oil production platforms. Specifically suitable for locations with strict fire-prevention requirements (such as flammable/explosive zones) and harsh environments. Also ideal for power supply and lighting in residential areas, commercial streets, industrial sites, and rural communities.
