Products Description
S11-S13 10-35kV transformer features:
1. Economical And Environmental Friendly With Good Performance
The transformer products in the S11-S13 series exhibit lower losses and currents compared to the S9 series. This is due to the continuously wound iron core, which has a circular cross-section, allowing full utilization of the silicon steel sheet’s orientation. The iron core structure remains naturally tightened, eliminating the need for clamps that could degrade performance. As a result, the no-load loss is reduced by 20-45%, and the no-load current decreases by 60%-80%.
2. Longer Life Of The Transformer
The fuel tank features a fully sealed design. It can be secured with bolts or welded at its edges, preventing any contact between the insulating oil and the air. This design slows the aging process of the insulating properties, thereby extending its service life.
3. Low Noise
The noise has been decreased by over 10 decibels. The transformer core is a seamless unit with a compact structure, resulting in an operational noise reduction of 7-10 dB. This makes it highly suitable for installation in buildings and residential areas.
4. Reliable Operation
The components within the fuel tank have been enhanced, increasing reliability and elevating the technological standard to ensure a secure seal.
5. The Transformer Is Small In Size
The S11 and S13 models utilize corrugated plate radiators. As the oil temperature fluctuates, the corrugated plates expand and contract, effectively taking on the function of an oil conservator.
