The reel core fully sealed distribution transformer is a new generation of low noise and low loss transformer developed in recent years. Its iron core has no joint, greatly reduces the no-load loss and no-load current, reduces the no-load current by 60%~80%, the high and low coils are continuously coiled on the core column, the winding is tight, the concentricity is good, and the product is enhanced more. Anti-theft performance. The noise decreased by more than 10 decibels. The temperature rise is low 16-20K. Because of the continuous winding of iron core (cross section is pure circle), the orientation loss of silicon steel sheet is fully utilized, and the no-load loss is reduced by 20%~30%.
The low voltage winding with capacity in the 630~2500kVA enclosure is made of cylinder or spiral structure with high mechanical strength and balanced ampere distribution. The product has good short circuit resistance.
The positioning structure is added to the body so that it does not produce displacement during the transportation process, and all fasteners are equipped with fastener nuts to ensure that the fasteners are not loose during the long run of the product and meet the requirements of the non core lifting.
