■ 結構特點
Structural Features
▲ 鐵心：在高精度剪切線，利用陶瓷刀具剪切，采用高導磁優質硅鋼片，多組全斜接縫步進搭接，綁扎結
構，滿足變壓器低空載損耗和低噪聲水平的要求。
Core: In the high-precision shear line, use ceramic cutting tools to shear, and use high-quality
silicon steel with high permeability, multi- group of mitre stepping lap joint and banding structure
to satisfy the low load loss and low noise level requirements of transformer.
▲ 繞組：采用優質無氧銅制造，結構并聯導線之間的合理換位，有效降低了變壓器負載損耗。通過優化冷卻
回路設計，對繞組線匝進行可靠綁扎和夾緊，提高了變壓器安全運行水平。
Winding: it is made by high-quality oxygen-free copper. The rational transposition between
structure parallel wires has effectively reduced the transformer load losses. By optimizing the
cooling circuit design, the winding wire turn can be banded and clamped reliably which improves the
safe operation level of the transformer.
▲ 油箱：全密封產品采用波紋油箱或膨脹式散熱器油箱。二氧化碳保護焊工藝，優選密封材料并對密封表面
進行加工，結構嚴格的檢漏試驗程序，確保變壓器無滲漏。新型片式散熱器或波紋油箱的使用，大大提高了變壓器
外觀質量。
Tank: the omniseal products adopt corrugated tank or expansion-type radiator tank. Carbon dioxide
arc welding process selects sealing material and processes the seal surface, structure; leak test
procedures with rigorous structure ensures no leakage from the transformer. Using new plate radiator
or corrugated tank has greatly improved the appearance quality of the transformer.
▲ 表面處理與涂層：對油箱表面進行精細處理，并噴涂于特殊防腐油漆，保證涂層不脫落，鋼結構件無銹
蝕。
Surface treatment and coating: fine treatment of the tank surface and frame plating with the
special anti-corrosion paint can ensure that the coating does not fall off, and steel structure has
no rust.
