The reel core fully sealed power 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 corrugated oil tank is adopted in the transformer, and the oil conservator is cancelled, the box cover and the box edge are completely welded or fastened by bolts, thus prolonging the service life of transformer oil.
The product surface is painted, primed and topcoat after degreasing, rust removing and phosphating. It can meet the special requirements of metallurgy, petrochemical system and wet dirty area.
A fully sealed transformer oil tank is used. The pressure release valve, signal thermometer and gas relay are installed according to the standard, so as to ensure the safe operation of the transformer. This series of products has beautiful appearance, small size, and can reduce the installation area. It is an ideal free maintenance quality product.
