Product Description
Combined transformer(commonly known as American style box type transformer) is a transformer that combines the transformer body, HV load switch, fuses and other related auxiliary equipment. Connection methods for high voltage mainly include ring connection and terminal connection, which can meet the requirements of various power supply systems. It has the advantages of compact design, small size and footprint, low investment and fast installation.
1. Fully insulated structure and interlock device to ensure personal safety.
2. Fully sealed structure can prevent or slow down the deterioration of the oil and prolong the service life of the transformer.
3. The high-voltage side adopts the dual fuse protection.
4. The iron cores include silicon steel sheet iron core, amorphous alloy iron core, rolled iron cores, etc.
5. The high-voltage incoming applies the line cable connector structure, fully insulated, safe, reliable, easy to operate.
6. Small size, only about 1/3 of the European-style box type transformer of the same capacity.
The above standards are subject to the latest released information; Equipment requirements should be based on the corresponding latest national professional standards.
