Product Description

PRODUCT DETAILS

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.
