FEATURES

\ FEATURES \ LOSS LOSS \ LOW NOISE \ STABLE & RELIABLE \

1. 7-stage temperature control technology system, which combined with the temperature field dinite element analysis, to ensure full play to the performance advantages of various insulation materials.
2. The insulation system is based on DuPont Nomex ® Insulation paper technology.
3. Low noise: Unique noise reduction measures are adopted in different parts to ensure that the noise control is better than the national standards.
4. Low loss: The core is made of high-quality cold-rolled silicon steel sheet with high magnetic conductivity, using the Swiss core automatic laminating machine or longitudinal and transverse shearing, multi-stage full-slant seam automatic laminating, core tying using overall pressure and PET tape tying process, effectively reducing the no-load loss and no-load current of the transformer.
5. No leakage: The oil tank and oil storage cabinet have been tested for positive and negative pressure to ensure that there will be no oil leakage during normal operation. The components are installed with a flange groove structure, and all seals are made of high-quality once-formed acrylate rubber parts to prevent il-leakage.
6. Strong short circuit resistance: The transformer coils are calculated with reasonable ampere-turn balance and semi-rigid copper wire is used. The core claiming parts are calculated for strength and stiffness to meet the safety requirements of maximum short-circuit mechanical force. The winding pads are all densified and made of high-density rigid cardboard and adopted integra set & integral pressing to ensure the accuracy of assembly and the short-circuit resistance.
