Features:
1: The unique 3D wound iron core
The iron core are wound by wide running to narrow and then narrow running to wide Silicon steel sheet. The three semi-circle cores are wound separately firstly and then combined together. They form three pillar of wound core with cross section similar to round shape.
It does not need transverse cutting as well as no punching holes. It eliminates the transverse joint seam of traditional transformer and reduces magnetic resistance. The cross section of iron core is round and can reach the maximum filling in coefficient. The triangle 3D core structure ensures the magnetic loop of three phases is equal and shortest. It is the most ideal winding core structure for transformer recognized worldwide. The flat shape of core absolutely can mot match in this way. The 3D wound core is a significant breakthrough and upgrading for ironcore of transformer. So 3D triangular wound core transformer is universally recognized as energy saving, environmental friendly and super quiet power distribution transformer.

2: Less loss and noise
Compared with same capacity transformer, the no load loss reduce over 25% and no loss current reduce more than 70%, the noise level reduce 5dB-10dB.

3: Anti-theft
Due to technical reasons, stacked core transformer is easy to be stolen. Detaching the fastener of the body, knocking down the silicon steel sheet of transformer, then three winding can be separated with silicon steel sheet and they can be stolen very easily. Because the wound core is in a whole, it can not knocked off and winding can not be taken apart. It is quite difficult to move out the wound core and winding. Meanwhile, taking apart the silicon steel sheet and copper wire is not easy, so wound core transformer has good anti-theft performance.
