Product Description

For many years, high-quality materials and advanced technology have been utilized to produce 1kva-2000kva SG series of three-phase isolation transformers. These products comply with VDE0550, IEC 439, JB5555, and GB5226 international and national standards. SG series three-phase isolation transformers are widely used in AC 50/60HZ environments with input and output voltages not exceeding 1000V. The design covers various requirements including voltage levels, connection groups, tap positions, and winding capacity distribution. Key advantages include fire-proofing, moisture-proofing, safety, reliability, energy-saving, and convenient maintenance.
Three-Phase Isolation Transformer

Key Features

  • Interference Elimination: Setting up a new center line-earthing eliminates common-mode interference and other noise from the power network.
  • Wiring Versatility: Converts three-wire △ wiring into a four-wire Yo system.
  • Harmonic Reduction: Utilizing △/Yo isolating transformers can effectively remove the third harmonic and reduce interference signals.
  • Grid Purification: Prevents current distortion of nonlinear loads from affecting the power supply and returning to the grid.
  • Independent Neutral Line: Produces a new neutral line so equipment remains independent of the grid's neutral line issues.
