D11, D13, D20 Series Single-Phase Oil-Immersed Transformers

Single-phase oil-immersed wound core distribution transformer. The core is a single-frame dual-limb wound structure, with outer layer spot welding without binding. High-quality cold-rolled silicon steel sheets are selected and sheared by high-performance longitudinal shearing lines, effectively controlling the burr of silicon steel sheets within 0.02mm; the high and low voltage windings of the transformer are wound with high-quality oxygen-free copper wire using advanced processes. Due to the selection of new materials, new processes and advanced production equipment, the no-load and load losses of the transformer are significantly reduced, and the performance and structure are more reliable and superior. It is a new product key promoted by the state.
