High voltage oil type electric power transformer 200kva 500kva 630kva 800kva 1000kva
High voltage oil type electric power transformer 200kva 500kva 630kva 800kva 1000kva is different from the general oil immersed transformer. It cancels the oil storage tank and uses the corrugated plate heat sink of the oil storage tank to radiating & cooling, which to compensate the increase or decrease of oil volume by its elastic expansion and contraction.
The application of High voltage oil type electric power transformer 200kva
All series of transformer are suitable for 10kV, 20kV and 35kV power transmission and distribution systems, and can be used for power and lighting in residential areas, commercial streets, industrial and mining enterprises and rural areas.
