Z2/XBJ2 24kV(20kV) Intelligent/Compact Box-type Substation

With the development of china’s economy, the rapid increase in electricity consumption in cities and towns, especially in urban areas, the load density increases faster, some towns and cities for power grid construction and renovation planning, will be unqualified for the original distribution voltage level and maintenance difficulties in the power grid for the upgrading and renovation. China's urban network transformation should learn from some of the beneficial experience of foreign countries, foreign technical and economic comparisons uniformly proved that the 24kV program is superior to the 24kV program. This is not only because 24kV and 12kV compared to its power supply radius and capacity almost doubled than the latter, while reducing, losses and unit capacity of construction investment and maintenance costs, to avoid large-scale demolition and replacement, saving investment, Some of china's high load density of cities, continue along the 12kV extension will be difficult to continue. City network transformation 12kV upgraded to 24kV is the future development trend, there are some provinces and cities have begun to pilot. XBZ2 intelligent /XBJ2 compact 24kV(20kV box-type substation is the Tianjin Electric Traditional Design institute, China Electrical Apparatus Industry Association electric control and distribution equipment branch organization of the country's more than seventy enterprises, in order to meet the needs of the national economy is increasingly developing for the characteristics of China's national conditions. In order to meet the needs of the growing national economy and the characteristics of China's national conditions, and to meet the needs of the national power grid, and develop a new generation of 24kV box-type substation through the type test.
