Main Functions and Features
Daelim brand 220kV, 110kV and 66kV low-loss series transformer is our independently developed new generation of transformers on the basis of absorption of domestic and foreign advanced technology, which features low local discharge, low loss, low noise, high reliability, strong protection against abrupt short circuit. Its excellent performance has been recognized by wide users and highly appraised by experts. The full-sealed suspending-cover free products sell well nationwide. Amount of local discharge: The apparent discharge amount under 1.5 times of rated voltage is less than 80pC; Noise: Products of 63MVA and below is lower than 58dB(AN); Power loss: No-load loss is 30% lower than that of IEC standart; Reliability: All in-service products have no damages or oil leakage occurred; Short circuit withstanding: Model SFZ11-50000/132 smoothly passed the short-curcuit withstanding test of the national transformer quality supervision and inspection center and also passed Holland "KEMA" quality control system.

-Amount of local discharge: the apparent discharge amount under 1.5 times of rated voltage is less than 80pC;
-Noise: products of 63MVA and below is lower than 58dB(AN);
-Power loss: no-load loss is 30% lower than that of IEC standard;
-Reliability: All in-service products have no damages or oil leakage occurred;
-Short circuit withstanding: Model SFZ11-50000/132 smoothly passed the short-circuit withstanding test of the national transformer quality supervision and inspection center and also passed Holland ‘KEMA’ quality Control System.
The high-voltage(HV) coil adopts an interleaved - continuous structure to improve the voltage characteristics under impact voltage and make voltage evenly distributed. All stays and pads are chamfered to keep highly reliable insulation.
In the transformer winding there is a zigzag oil guide structure so as to fully coll all areas inside the winding, lower the temperature rise of the winding and the hot points of the winding and prolong the service life of insulation. The HV and MV regulation system are independently provided with voltage-regulating winding to balance the ampere turn of each winding, effectively lower the axial electrodynamic force generated at short-circuit of transformer and improve abrupt short-circuit withstanding capacity.
The winding adopts radial ‘0’ margin design, between the core and the paper sleeve of LV winding, and between the LV, HV, voltage -regulating windings, as well as before insertion of stays and shroud plate they are fully dried and tightly matched to ensure extremely good compactness and concentricity of the entire winding.
The core is made of high-permeable grain-orientated top quality cold-rolled silicon sheet and the material is cut with advanced Germany Geoge GmbH automatic shear line with the cuts burrs controlled within 0.02mm.
The silicon sheet fabrication adopts ‘no-upper yoke-lapped’ technology and all lapped joints of the silicon sheet are 45°full-miters. The laminated core sheets are integrally pressed and adhered with epoxy resin to make the three-leg two-yoke core a strong and flat integral one with good verticality precision, this effectively improves no-load performance and reduce noise.
Bracing plates are used as support between coil leg and inner coil. The iron yoke is tied with epoxy resin-impregnated glass fiber band, and the lower iron yoke and the lower section of oil tank is tightened with counter-pressure bolts. The upper iron yoke and the upper section of oil tank are fixed at 3 locations. Hence the body inside the oil tank can withstand the vibration during transportation without any shift.
Oil tank and accessories
The tank wall adopts wide steel sheet, which will be folded into corrugated structure without splicing, in this way welds are decreased and mechanical strength is enhanced; meanwhile, the corrugated wall has diverging effect, and thus plays a role in decrease of noise. The routing troughs and control cabinets of the secondary circuit are all made of stainless steel, so the entire transformer has a simple and good looking.
All sealing surface use quality material and are precision-machined.
On the edge of the tank there are double sealing grooves, and the outer sealing material is used to shade the atmosphere and ultra-ray to protect the inner sealing being damaged, thus at utmost prolonging service life and enhancing reliability of the seal.
