Summary
With the increase of power load, the disadvantages of original 10kV power distribution system will appear such as small capacity, large loss, short power supply radius, and occupation of many channels and much land, and the contradiction between the construction of power distribution network and the use of land resources is increasingly highlighted. 10KV power distribution system has been unable to meet the requirements, and increasing the voltage from 10KV to 20KV may result in a 75% reduction of line energy loss and a 60% increase of power supply radius, as well as save the transformer substation number and land and reduce the line and corridor lamp resources. transformers products. Product load current, load loss decreased significantly smaller operating noise, more compact, energy-efficient three-dimensional wound core transformer new

1. Brief Description
With the increase of power load, the disadvantages of original 10kV power distribution system will appear such as small capacity, large loss, short power supply radius, and occupation of many channels and much land, and the contradiction between the construction of power distribution network and the use of land resources is increasingly highlighted. 10KV power distribution system has been unable to meet the requirements, and increasing the voltage from 10KV to 20KV may result in a 75% reduction of line energy loss and a 60% increase of power supply radius, as well as save the transformer substation number and land and reduce the line and corridor lamp resources. In the process of transforming from 10KV system to 20KV system, there is such situation that the 10KV power supply system needs to be transformed to 20KV system after it is used for a short period of time. This product may convert between 10KV and 20KV voltages, and the user doesn't need to make second input, thus saving the investment. 

2. Application Scope
The product applies to the areas where the load density is high and the power demand grows rapidly, the emerging areas or the areas where the infrastructure of present power grid is weak.
