Oil Immersed Hermetically Sealed Transformer Advantage:
• Yuanguang Intelec utilizes a focus factory concept which leads to a great experience in specific products giving a very high level of consistency in design, manufacture, and test.
• Yuanguang Intelec distribution transformers factories utilize the common design platform giving us best-in-class experience, consistency, and repeatability
• Yuanguang Intelec utilizes best-in-class manufacturing and quality processes to ensure that our transformers will meet the most stringent requirements
Three Phase Oil Immersed Transformer Transformer Applications:
• Yuanguang Intelec small distribution transformers up to 315 kVA are typically oil-immersed for pole, pad, or floor mounting.
• Yuanguang Intelec small distribution transformers up to 315 kVA are suitable for residential overhead distribution loads, as well as light commercial or industrial loads and diverse power applications.
3 Phase Distribution Transformer Features:
1.The low-voltage windings of oil-immersed transformers generally adopt a cylindrical structure with copper foil around the shaft, except for small-capacity copper wires; the high-voltage windings adopt a multi-layer cylindrical structure to balance the ampere-turn distribution of the winding and prevent magnetic flux leakage Small, high mechanical strength, strong short circuit resistance.
2.The iron core and the winding have adopted fastening measures respectively. The fastening parts such as the height of the active part and the low-voltage lead wire are all equipped with self-locking locknuts. The non-hanging core structure is adopted, which can withstand the vibration of transportation.
3.The coil and iron core are vacuum-dried, and the transformer oil is vacuum-filtered and oil-filled to minimize the moisture inside the transformer.
4.The oil tank adopts corrugated sheet, which has a breathing function to compensate the volume change of oil caused by temperature changes, so this product does not have an oil storage tank, which obviously reduces the height of the transformer.
5.Because the corrugated sheet replaces the oil conservator, the transformer oil is isolated from the outside world, which effectively prevents the entry of oxygen and water and leads to the decline of insulation performance.
6.According to the above five points of performance, it is guaranteed that the oil-immersed transformer does not need to change oil during normal operation, which greatly reduces the maintenance cost of the transformer and prolongs the service life of the transformer.
