    China 50hz Frequency Oil Immersed Distribution Transformer No Load Voltage Regulation

    110kV Three-Phase Triplex Windings, No-Load Voltage Regulation, Power Transformer


    Product Introduction

    330kV power transformers produced by Daelim comply with standard IEC 60076 and requirements

    of three phase immersed power transformer”. The core is made of superior grain-oriented cold- rolled

    silicon steel sheets and all inclined lapped joints without drilled holes while the coils are made of coppe

    r free of Oxygen with beautiful appearance and safe running. They are widely applied to power

    transmission & distribution of urban & rual network. These transformers are widely applied to eletrolysis

    , transmission, traction, DC transmission and electrostatic precipitation fields. These transformers are

    certified by KEMA, CESI, V-check, CTQC, ISO9001 & 14001 and CE,. Daelim is a worldwide partner for

    all power applications and industrial companies-Accordingly, the examples of our work are Global:

    Whether in South America, Asia or Europe, Whether in the desert or in specially demanding Applications.

    Thousands of plants run efficiently and reliably with our technology.

    Main functions and features


    1.General

    330kV 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 85dB(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 systom.

    2.Coil

    The high-voltage 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 cool all areas inside the winding, lower the

    temperature rise of the winding and the hot point 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.

    3.Core

    The core is made of high-permeable grain-orientated top quality cold-rolled silicon

    sheet and the material is cut with advanced Germany GmbH automatic shear line with

    the cut 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
