1.Product Description
The European type substation, is a complete set of new power transformer equipment developed by our company on the basis of transformation of national urban network making the optimal combination for the oil-immersed sealed power transformer and high and low voltage electrical components. Through structure optimization, the switchgear shall be miniaturized to extreme extent which greatly reduce the occupied area of the combined transformer with such advantages as small volume, low noise, reliable power supply, reasonable structure, blexible for installation, easy for operation and capable of going deep into the load center to maximum extent, etc.It can assemble network automation terminal (FTU) in the high-voltage ring network cabinet, realize the reliable detection of short circuit and single-phase grounding fault, and has the function of "four remote", which facilitates the automatic upgrade of network distribution. It is widely used in residential quarters commercial centers stations industrial and mining enterprises airports railroads schools hospitals, high-rise buildings and places.
