500kVA/630kVA 20 KV Oil Immersed Transformer

500kVA/630kVA 20 KV Oil Immersed Transformer Oil Immersed Transformer,Hermetically Sealed Oil Filled Transformer,Immersed Transformer,Oil Filled Distribution Transformers,Power-Saving Oil-Immersed Transformer, 500kVA/630kVA oil-immersed transformer is a commonly used distribution transformer, which has the characteristics of durability, safety and reliability, and is widely used in industrial and mining enterprises, transportation, railways, urban and rural power grids and other fields. Main advantages of copper core are: 1, high efficiency, low loss: copper core than aluminum core conductivity is better, oil-immersed transformer resistivity is lower, can better meet the requirements of high efficiency and energy saving. 2, long service life: copper core oil-immersed crosspressure has high conductivity, which can reduce energy loss, improve service life and reduce maintenance costs. 3, good stability: the copper material itself is hard, not easy to deformation, so the sta…
