Product features:  
Reduce the power loss of the power grid: 10kV is increased to 20kV. Under the condition of transmitting the same power, the line current can be reduced by 50% and the line power loss can be reduced by 75%.

Increase power supply capacity: the transmission distance can be doubled under the condition of ensuring voltage quality by transmitting the same power and using wires with the same section; Under the same power supply radius, the transmission power can be doubled by using wires with the same section.

Saving one-time investment cost: for distribution lines alone, it can save more than 1 / 3 of non-ferrous metal consumption and about 40% of line infrastructure investment. With the gradual increase of load density, the difference between the construction cost of the distribution network with 10KV voltage level and that with 20kV voltage level increases gradually. When the load density increases to 50MW / km ²， The difference of total construction cost is up to 20%. At the same time, adopting 20mkv voltage level can greatly reduce the distribution density of the substation, thus reducing the construction investment.

Simple operation and maintenance: reduce 10kV power transmission and transformation links to significantly reduce the operation and maintenance cost.

The product performance parameters refer to GB / t25289-2010 technical parameters and requirements for 20kV three-phase oil immersed distribution transformers. The no-load loss and load loss implement the standard parameters, and the no-load current is reduced by 80% on average.
