480V Dry Type Three Phase Isolation Transformer Grain Oriented Silicon Steel
Features
▶ The primary side and the secondary side of the electrical are completely insulated from the loop isolation. Further, the use of the characteristics of the core of the high-frequency loss is large to suppress the high frequency noise incoming control loop. Isolation transformer's secondary suspended and can only be used in the smaller range of power supply lines shorter occasions. At this point, the system-to- ground capacitance current was insufficient to harm the persons.
