SG 3 phase Isolation Transformer(100 kva Isolation Transformer), is natural cooling indoor, it is applicable to the circuit of AC 50Hz~60Hz, 1000V and below. It(50 kva Isolation Transformer) can be used in control power, local lighting and indicating power supply of machine tool mechanical equipment and other general electric appliance, also be used as small type power.

(45 kva Isolation Transformer)Meets the standard: Q/ZT 525.

Altitude: not exceed 2000m.
Ambient temperature: -5°C~+40°C (limit value -25°C).
Relative humidity is not more than 50% at +40°C. Relative humidity can be higher at the lower temperature. The monthly average max relative humidity of wetest month is 90%, and the average monthly min temperature of the month is +25°C.
In the ambient, there should not has the gas and dust that corroding metal, destroying insulation. The transformer should not be corroded by water, rain or snow.
There is no serious vibration and bumps at the installation site.
The power(10 kva Isolation Transformer) supply voltage waveform is an actual sine wave, and the three-phase power supply is approximately symmetrical.

The transformers(25 kva Isolation Transformer) have two body types: exposed and fence. It has the advantage of low consumption, small noise, better performance against fire and free of pollution etc. The shell of the protective type is made of steel plate, the transformer is in the shell. There are several holes outside the shell to installation the power lines. In addition, this type can add the monitor meter of the voltage and current according to the customer request, And if the capacity is above 80KVA, it can also add the axial flow fan or wheels for moving.

Note:
1. The dimensions of the above only for reference, when the input current is more than 300A, the customer need to order specially, and the size will change correspondingly.
2. You can choose the rated input/output voltage in the sheet arbitrarily according to the demand.
3. The voltage and size out of the sheet, should confer with consumer on their demand.
4. SG-100kVA Isolation Transformer and above fence type transformer body have wheels and fan cooling system, with ammeter and voltmeter, as fig.5.
5. SG-4kVA~50kVA Isolation Transformer fence type transformer only have body, with one indicator light of power, as fig.3, fig.4.
6. SG-0.3kVA~3kVA 10kVA Isolation Transformer fence type transformer's wiring terminals are outside, with an indicator light of power, as fig.2.
