Features of Low Voltage Split Dry Type Transformers with Enclosure
Split-Winding Structure: It's dual independent windings allow for dual voltage outputs or redundant power paths, improving fault tolerance and load management.
Reliable Operation: During a fault in one split winding, the other maintains partial voltage, limiting short-circuit current to 1/4~1/3 of the rated current.
Robust Enclosure Design: IP54/55-rated protection against dust, moisture, and environmental contaminants.
Dry-Type Insulation: Cast resin insulation ensures fire safety (non-flammable, self-extinguishing) and eliminates oil leaks.
Low maintenance: The dry design does not require oil-based cooling, which reduces maintenance costs and improves safety.
Compact and space-saving: The transformer 's Compact design with integrated enclosure reduces installation footprint.
Advatages of Low Voltage Split Dry Type Transformers with Enclosure
Enhanced Safety: The dual low voltage design of this transformer results in high impedance, while the high impedance design significantly reduces the impact of short-circuit current on the system.
High reliability of power supply: When one of its split windings is short circuited, the other winding can still maintain a lower voltage, so a single-sided fault does not affect the operation of the load on the other side.
