Three phase autotransformer

SG, SGG series self coupling, isolationtransformerOur company has been producing using high-quality materials and manufacturing techniques for many years. It can penetrate deep into the load center. Mainly used for various power supply locations with an AC frequency of 50-60Hz and a voltage not exceeding 500V. The allocation of various input and output voltages, connection groups, and tap line group capacities of the product can be carefully designed and manufactured according to user requirements. It has the advantages of fire prevention, moisture resistance, safety and reliability, energy conservation, and easy maintenance. Product performance: Efficiency: ≥ 98% Waveform distortion: No additional waveform distortion Function: With indication protection for input voltage, output voltage, current, etc. Insulation resistance: ≥ 50M Ω Electrical strength: Power frequency sine voltage 2000V for 1 minute without breakdown or flashover Overload capacity: twice the rated current, maintained for 1 minute Environmental temperature: -15 ℃ -40 ℃ Altitude: ＜ 1000M Relative humidity: ＜ 90% Attention: The installation site has no gas vapor, chemical deposition, dust, dirt, or other explosive and corrosive media that seriously affect the insulation of the transformer.
