Product description
The isolation transformer is divided into single-phase (DG) and three-phase (SG) series. The main function is to isolate the electrical equipment from the power grid for safety or anti-interference (multiple D/Y, D/Yn connection). In the occasion, there is no direct electrical connection between the electrical equipment and the power supply. It is widely used in the transmission and distribution of subways, high-rise buildings, airports, stations, terminals, industrial and mining enterprises and tunnels, and the use of imported and exported equipment.

Product nature
The isolation transformer is a safe power source, which is generally used for protection, lightning protection and filtering of machine maintenance. Usually, we use an AC power supply voltage connected to the ground and a 220V potential difference between the other line and the ground. Human contact can cause electric shock. The secondary of the isolation transformer is not connected to the earth, and there is no potential difference between any two lines and the earth. There is no electric shock when people touch any line. Secondly, the output of the isolation transformer is completely "opened" from the input, which effectively acts as a good filter for the input of the transformer, thus providing a pure power supply voltage to the consumer!

Product function
The main function of the isolating transformer is to completely insulate the primary side from the secondary side and also isolate the circuit. In addition, the high-frequency loss of the iron core is utilized, so that high-frequency clutter is transmitted to the control loop. The isolation transformer is used to suspend the secondary grounding, and it can only be used in the occasions where the power supply range is small and the line is short. At this point, the system's capacitance to ground capacitance is not small enough to cause personal injury. Another important role is to protect personal safety! Isolate dangerous voltages.

Features
1. Low loss and high efficiency: The inner core of the transformer is made of imported high quality new silicon steel sheet and high temperature resistant glass wire covered wire.
2, long service life: internal insulation type H-class insulation, insulation heat resistance coefficient is extremely high.
