Detailed description
The 1000 kVA oil immersed transformer is a high-capacity three-phase power distribution solution for industrial facilities, urban distribution networks, and high-load applications. It provides reliable power for heavy machinery, multiple production lines, and high-rise buildings, supporting continuous operation and simultaneous startup of multiple loads.
The oil immersed transformer features a step-lap laminated core made of high-permeability CRGO silicon steel and high- and low-voltage windings wound with oxygen-free copper conductors. The core and windings are fully sealed in a corrugated oil tank filled with high-quality transformer oil, ensuring effective insulation, heat dissipation, and low operating noise. The multilayer winding structure enhances short-circuit withstand capability and long-term reliability.
Standard configuration includes Dyn11 vector group, HV ratings of 10 kV / 35 kV (optional 6 kV / 20 kV), and a 400 V LV output in a three-phase four-wire system. ONAN cooling is standard, with optional ONAF cooling increasing capacity by approximately 20%–30%. The transformer is rated IP30 for indoor use, with an optional IP54 enclosure for outdoor installations.
Complying with National Level 1 Energy Efficiency standards, the 1000 kva oil filled transformer delivers low losses and stable voltage output. With a short-circuit impedance of 6%–8%, high-quality insulating oil, and a sealed tank design, oil immersed transformer offers strong short-circuit resistance, low maintenance requirements, and a service life exceeding 20 years.
