SG three-phase isolation transformer features:

 1) Safe, fireproof and pollution-free, it can be directly operated in the load center.

 2) High mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life.

 3) Low loss, low noise, and obvious energy saving effect.

 4) Good heat dissipation performance, strong overload capacity, can increase capacity operation when forced air cooling.

 5) Good moisture-proof performance, suitable for operation in high humidity and other harsh environments.

 6) Small size, light weight, small footprint and low installation cost.

 7) With voltage conversion function (such as: △/Yo or Yo/△ connection)

 8) It has the function of filtering and anti-interference (for example: it can remove the third harmonic interference function. It can remove the odd harmonic interference.)

 9) Can effectively suppress the disturbance harmonics and lightning electromagnetic pulses induced from the power line to interfere with the system

 10) It can effectively suppress the disturbance harmonics emitted by the electronic equipment of this system from entering the power distribution network and causing interference to other equipment (devices and systems)

 11) Can fundamentally prevent system malfunction, data loss or error caused by ground potential disturbance

 12) It can effectively prevent the hardware equipment in the system from being destroyed by counterattack due to the sharp rise of the potential of the steel bar as the reference ground when the lightning protection device of the building is connected.

 13) The biggest reason why isolation transformers are widely used in construction is that isolation transformers are 1 to 1 transformers. The primary is 220v, and the secondary is also 220v. The alternating current we use is connected to the earth with one wire. There is a potential difference of 220V between the other wire and the ground. Human contact can cause electric shock. The secondary of the isolation transformer is not connected to the ground, and there is no potential difference between any two lines of it and the ground. People will not get an electric shock if they touch any line, so it is relatively safe. Isolation transformers are often used in electronic instruments with electronic tubes and high working voltages, such as tube amplifiers, oscilloscopes, etc., and can also be used for power supply maintenance.
