大同Energy Efficient Amorphous Core Distribution Transformers
产品描述
The core is a rolled core structure, three-phase five-column type, rectangular cross-section, high voltage is wound by acetal enameled wire, low voltage is wound by oxygen-free copper wire or copper foil, which increases the ability of the transformer to withstand short circuits.
The transformer connection group uses Dyn11 to avoid the influence of higher harmonics, and has a strong ability to withstand unbalanced loads, which significantly improves the power supply quality. The transformer uses vacuum oiling, which can completely eliminate air bubbles in the coil and ensure stable insulation performance.
