Oil Type Power Distribution Transformer


Pad Mounted Power Distribution Transformer


45kva Oil Type Transformer

Product Description

45KVA Three Phase Pad Mounted Oil Type Transformer Loop Feed Type Combined Distribution Transformer




1)There is no oil storage tank the height of the transformer is reduced,Can save installation space and transportation costs.
2)The elasticity of the corrugated radiator can compensate the oil volume change caused by the temperature change.
3)The box is the corrugated radiator tank, not only has the cooling function but also has the 'breathing' function.
4)the transformer oil does not contact with the air, which effectively prevents the oxygen and water from immersing the transformer and leading to the deterioration of performance (aging of materials and oil).
5)New structure of high and low voltage winding, reasonable arrangement for oil tube and connection which increasing the capacity of mechanical strength and anti-shortcut.
6)We employ spiral loops with longitudinal oil path to produce a better cooling effect. We improve the effectual support of the loop's terminal face to strengthen the anti-short circuit electricity capability.
