Advantages of the Three-Phase Oil-Immersed Transformer Sh15-400KVA
The silicon steel core is constructed from 0.18 ~ 0.3 mm oriented silicon steel sheets, precisely punched and stacked, ensuring excellent stability.
The coil is made of high-purity copper, with acetal enamelled wire for high voltage and oxygen-free copper conductors or copper foil for low voltage, enhancing resistance to short-circuits.
The Dyn11 connection symbol is adopted to minimize the impact of higher harmonics, providing strong resistance to unbalanced loads and improving power supply quality.
Vacuum oiling technology is applied to eliminate bubbles in the core, thereby ensuring reliable and consistent insulation performance.
