4. Product Advantages
Core: The 45° full-slant step joint process is adopted to effectively reduce no-load loss, no-load current and core noise.
The clamp and pull plate structure are used to make the core as a whole stable and firm, thereby improving the ability to resist short circuits and impacts.
Coil: The high voltage adopts a cylindrical type, and the low voltage adopts a cylindrical type or foil type, which improves the ability to resist short circuits.
An oil guide structure is provided inside the winding to improve the oil flow path, thereby reducing temperature rise and improving load capacity.
Oil tank: It is a fully sealed bell-shaped structure, and the oil tank reinforcement iron adopts a corrugated folding plate structure, with fewer welds and high mechanical strength.
The cooling device adopts a plate radiator, which has a faster circulation speed, high heat dissipation efficiency, and improved overload capacity.
Body: All insulating parts and the welding parts of the winding head and lead wire are rounded.
The upper and lower parts of the body are positioned with rigidity to ensure that the body does not shift under various transportation conditions.
