It creatively reformed laminated magnetic structure of power transformers and three-phase layout, more optimized product performance, such as three-phase magnetic circuit is completely symmetrical, energy-saving effect is remarkable, greatly reduced noise, stronger overload, compact structure and small volume, etc.  3D Wound Core Structure  3D wound core - Continuously wound 1-piece core ring assembled using automatic winding machine (negligible number of joints and air gaps present results in low stray magnetic loss). 3 identical core rings are combined to make a 3 phase core.3D wound core – Each core ring limb resembles a semi-circle allowing 2 core ring limbs of equal cross section to combine to make a core limb. Cross section of core limbs takes closer shape of a circle, with a higher filling factor of approx. 98% resulting in magnetic flux being almost fully utilized.3D wound core - The different magnetic path directions of both core ring limbs that make a core limb combine to achieve zero vector sum for the magnetic flux, resulting in magnetic flux being balanced in each phase. Magnetic path of 3 phases are of equal distance, resulting in 3 phases having better balanced magnetic circuits and reduced exciting currentsCharacteristics of the 3D wound core transformerBalanced magnetic circuits and exciting current in all 3 phasesLower no-load lossesReduced vibrationsReduced in-rush currentsBetter short circuit withstanding capabilityReduced exciting (a.k.a. reactive or no-load) currentsCompact structure, low operating sound levelsMachines for 3D wound core transformersCRGO polyline slitting machineMax. dia. of core limb: 230mm (plane), 350mm (3D)Limb sectional area: polygonSlitting strip number: 2Working speed: 30m/min Max. raw coil width: 450mmSlitting width precision ±0.2mmStrip burr: ≤0.03mmCore winding machineMax. dia. of core limb: 230mm (plane), 350mm (3D)Limb sectional area: polygonWinding diameter: R650mm, R800mmWorking speed: 0~36r/minMotor power: 5.5KW/7.5KWCoil winding machinetransformer capacity range: 50～1600KVA main power: 3KWrotating power: 1.1KW
