Three phase step down transformer

Three phase step down transformer product description:

Three phase step down transformers are used to directly reduce the power supply of 20kV power grids into 400V power distribution power supply or 10kV power transmission power supply. Because of its significant advantages, it is used in more and more projects.

Three phase step down transformers main advantages are as follows:

1. It has obvious social benefit to reduce the construction of land area and multi-stage power transformation project.

2. Save project investment, improve economic benefits.

3. Reduce 10kV transmission and transformation link, so that the operation and maintenance costs are significantly reduced.

4. High voltage and small current are used to replace low voltage and large current to reduce line loss and line operating cost.

5. The 20kV power supply directly enters the user center, effectively improving the reliability of the power supply.

Three phase step down transformer iron core is made of quality cold-rolled silicon steel sheet, and in full-miter non-puncture structure. The coil is made of quality oxygen-free copper, featuring good outlook and safe running. The products are widely used in power transmission and distribution of industrial and agricultural power networks.

Load-ratio voltage regulation, high reliability, advanced level of performances, reasonable economical indicators. Three phase step down transformer core joints are of stepped shape with 3 steps, and the surface of the core is coated with cured paint to lower losses and noise.

Three phase step down transformer winding has novel structure and its oil passage is reasonable designed. Its newly designed insulation structure helps enchance its mechanical strength and the short circuit withstanding ability.The oil tank is in two types – fully enclosed type and the type fitted with an oil conservator.
