Pre-assembled Substaion (American Type)

1. Compact in structure : the volume is only 1/3 1/5 that of european type and its height is limited 1.5 meter. 2. Phase separating structure avoids oil pollution from transformer oil tank. 3. Double fusing element for full protection on high voltage side reduces cost greatly. 4. The product may be applied in ring main unit and in terminals as well . the cable head may be plugged in and pulled out when in emergency with a load current of 200A. 5. Enclosure made of alveolate double sandwich composite plate is heat insulating and heat dissipating as well. This is the ECC’s newly-developed technology which owns patent with its number of ZL00236211.2 issued by Chine Patent Bureau. 6. Undervoltage controller may be mounted on low voltage side to disconnect low voltage side load qukckly when abnormal voltage appears in system. 7. Oil-immersed load switch or SF6 load switch on high voltage side may be upgraded in a motor-driven way so as to a good foundation for automation of distributing grid. 8. Widely applied in urban electric grid reformation and public sites such as residential areas, enterprises, mines, hotes, airports, railways, wharfs, high speed roads and other indoor and outdoor places.
