Dry-type transformers using high-quality materials andadvanced technology produced,can be installed directly on the load of different nature.Dry-type transformers and autotransformers into SG SGG isolation transformer two kinds.Self-coupling transformer is a single-ring type transformer,suitable for mains voltage transformer required,no safety isolation requirements places.Isolation transformer is a double-winding transformer,the transformer in the grid not only function,but also can be input and output windings safe electrically isolated to avoid simultaneous access to live(or due to insulation damage and may live metal parts) and bring dangerous places,you can isolate the third harmonic power equipment,the protection of heat generated by the machine and prevent a decrease in life expectancy ofinsulating materials,and a variety of disturbancesplay a certain extent.
for AC 50HZ or 60HZ,input/output voltage and low voltage distribution sites within 1000V,commonly used in various types of imported equipment and the need for specialvoltage electricalequipment.
It is widely used as a power supply for various machine tools,bending machines,laser cutting machines,CNC punch presses, automated CNC machine tools,spindle motors,and export equipment.
