S11 oil immersed power transformer
Details
Product structure and features
Iron core: high permeability, low loss high-performance silicon steel sheet to reduce the no-load loss.
Coil: using high-quality QQ acetal enamelled round copper wire, oxygen-free copper rod made of flat copper wire or copper foil winding from the form of cylindrical,continuous, spiral, etc., with sufficient electrical strength, mechanical strength and heat dissipation capacity.
Oil tank: S11 series fully sealed oil-immersed distribution transformer is made of corrugated oil tank wave fins as cooling radiator, corrugated radiator is made of high-quality cold rolled sheet in special production line, wave fins can be up and down with the volume of transformer oil, thus making the transformer oil, the body of the transformer and the atmosphere to isolate, slowing down the aging, preventing the insulation from being damp, enhancing the reliability, and can be free of maintenance under normal operation.
