Q1: What is an SG Series low voltage dry isolation transformer with an IP20 cabinet?
It is a three phase low voltage dry transformer designed for electrical isolation and voltage conversion, with both primary and secondary windings rated below 1 kV. The transformer uses an open varnished winding structure and can be supplied with an optional IP20 metal protective cabinet.
Q2: What is the difference between an SG transformer and an SCB cast resin dry transformer?
The SG Series is a low-voltage open varnished dry transformer designed mainly for electrical isolation and voltage conversion, with both primary and secondary windings rated below 1 kV.
The SCB Series is a cast resin dry transformer generally used for medium-voltage power distribution, with a primary voltage of 10 kV or higher depending on the model.
The two product series are designed for different voltage levels and application requirements.
Q3: When should I choose the IP20 cabinet version?
The IP20 cabinet version is recommended for standalone indoor installation in workshops, equipment rooms and other areas where additional protection against accidental contact and solid objects is required.
The open type is more suitable when the transformer will be installed inside a closed machinery cabinet, control panel or equipment enclosure that already provides external protection.
Q4: What voltage ratios are commonly available?
Common voltage configurations include 400V to 400V, 400V to 208V, 400V to 230V, as well as other low-voltage combinations such as 440V and 660V.
Custom voltage ratios can be designed according to equipment and project requirements.
