Single-phase transformer product features: 1. Less material used The single-phase transformer with the same capacity uses 20% less iron and 10% less copper than the three-phase transformer. Especially when the wound core structure is adopted, the no-load loss of the transformer can be reduced by more than 15%, which will make the single-phase transformer manufacturing Both cost and cost of use are reduced, resulting in better life cycle cost. 2. Low line investment Using a single-phase power supply system in the power grid can save 33% to 63% of wires. Calculated according to economic current density, it can save 42% of wire weight. Calculated according to mechanical strength, it can reduce wire consumption by 66%. Therefore, it can reduce the cost of the entire transmission line. Construction Investment. This is very meaningful in terms of street lighting and residential electricity consumption in vast rural areas and towns. 3. Conducive to modern production Due to its simple structure, single-phase transformers are suitable for large-scale modern production, which is conducive to improving product quality and efficiency.
