SO series transformer is a kind of oil-immersed self-cooled low-voltage transformer based on AC voltage below 600V, which is widely used in different voltage places of enterprise power houses, government agencies, technical colleges and imported equipment clusters, and the equipment category is not restricted. Its advantages are stable performance, low power consumption and good anti-dust.

three-phase oil-immersed power transformer, the use of new insulation structure, improve the short-circuit resistance, the core of high quality cold-rolled grain-oriented silicon steel sheet; High and low voltage windings are made of high quality oxygen-free copper wire and multi-layer cylindrical process structure. All fasteners are special anti-loose treatment, high mechanical strength. The corrugated oil tank shell is a permanently sealed oil tank with its elasticity adapting to the expansion of oil, and has been widely used in various power distribution equipment.
