    Detailed Description

    2000kVA Oil Immersed Transformer Feature

    1.Adopts full oxygen-free copper windings, featuring ultra-low resistance to cut load loss and save long-term electricity costs.

    2.Strong short-circuit resistance structure, effectively resisting impact current and avoiding winding deformation during grid faults.

    3.Equipped with high-grade CRGO silicon steel core, greatly reducing no-load loss and operating noise below 56dB.

    4.ONAN natural oil-air cooling system delivers stable heat dissipation without extra cooling fans, lowering operation noise and power consumption.

    5.Hermetically sealed tank filled with PCB-free mineral oil, blocking moisture and dust to extend service life over 30 years with minimal maintenance.

    6.Dyn11 vector group, ±5% off-load tap changer ensures steady secondary voltage under fluctuating grid loads.
