Product Overview

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.

Model and Meaning

Normal working conditions and installation conditions

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.

Structure Feature

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.
