Product Overview
The S13 series three-phase oil-immersed transformers are high-efficiency energy-saving power transformers, designed and manufactured with a fully sealed corrugated tank structure. Temperature and volume changes of transformer oil caused by load fluctuations and ambient temperature variations are fully compensated by the corrugated tank, featuring a sleek appearance, compact footprint, and remarkable economic benefits. Compared with GB/T 6451 standards, S13-M transformers achieve an average 45% reduction in no-load losses, 35% reduction in load losses, and 30% decrease in operating costs, making it a sustainable choice for critical infrastructure projects requiring high efficiency and long-term durability.odel Definition
Features
● Voltage level: 10～35/0.4kV.
● Capacity: 30～3150kVA.
● Extended Lifespan & Maintenance-Free Operation:
Fully sealed design with bolted or welded tank cover-to-frame connections eliminates oil-air contact, preventing moisture ingress and significantly reducing insulation aging. This extends service life while enabling maintenance-free operation.
● Compact Design & Low Noise:
Utilizes advanced materials and manufacturing techniques to minimize operational noise. The oil conservator-free structure reduces overall height compared to conventional units. Lifetime oil retention eliminates the need for mid-life oil changes, enhancing in-service safety and reliability.
● Space-Efficient Corrugated Tank:
The S11 series features corrugated tank walls that provide natural cooling through thermal expansion and contraction. This design optimizes footprint while maintaining aesthetic appeal.
● Coreless Maintenance & Oil Purity:
Vacuum-filtered oil injection during assembly removes all moisture, ensuring long-term dielectric integrity. Hermetic sealing prevents oxygen ingress, eliminating oxidation risks and preserving insulation performance throughout the transformer’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.
