With the development of economic society and power grid, the application of 24KV voltage grade power supply in medium voltage distribution network has the following advantages.

· Increase the capacity of main transformer and improve the power supply capacity of substation.

· Improve the power transmission capacity of distribution lines and reduce the number of distribution lines.

· Increase the power supply radius of medium voltage line.

· Improve the power supply quality of medium voltage power grid.

· Reduce the power loss of medium voltage grid.

· Save nonferrous metals and land resources.

This voltage class was piloted in a small area earlier, and the 20KV voltage class was promoted on a pilot basis at the request of the State Grid Corporation. Now it is also planned to be promoted in other places and countries. It is predicted that 24KV devices will eventually dominate the market. Widely used in apply to 6 KV / 6.3 KV / 7.2 KV, 10 KV / 12 KV /

22 KV / 24 KV, 33 KV / 35 KV / 40.5 KV box type transformer high-voltage power distribution cabinet city network reconstruction, residential area, high-rise buildings, industrial and mining, hotels, shopping malls, airports, docks, highway, railway, oilfield and temporary electricity set inside and outside the workplace.
