On load tap changing oil immersed power transformer
Description:
*The oil-immersed power transformer adopts a new insulation structure to improve the ability of short circuit resistance.
*The core is Mmade 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 cylinder process structure.
*All fasteners adopt special anti-loose treatment, high mechanical strength.
*The corrugated tank shell is a permanently sealed tank with its own elasticity to adapt to the expansion of oil.
*It has been widely used in various distribution equipment.
