D11-M·R Series 10 kV Single-Phase Wound-Core Power Transformer

This product complies with the national standards GB 1094 “Power Transformers” and JB/T 10317-2014 “Technical Parameters and Requirements for Single‑Phase Oil‑Immersed Distribution Transformers.” The D11‑M R‑10‑160/10 series is a single‑phase oil‑immersed distribution transformer featuring a rolled‑core design with a single‑frame, double‑column structure; the outer layers are spot‑welded rather than bound. High‑quality cold‑rolled silicon steel sheets are selected and cut on a high‑performance longitudinal slitting line, ensuring that burr heights are kept below 0.02 mm. Both the high‑ and low‑voltage windings are wound using premium oxygen‑free copper wire and advanced manufacturing processes. Thanks to the adoption of new materials, innovative manufacturing techniques, and state‑of‑the‑art production equipment, the transformer exhibits significantly reduced no‑load and load losses, with enhanced reliability and superior performance. It is a key new product currently being promoted nationwide.

Product Description

　　Overview

　　This product complies with the national standards GB 1094 “Power Transformers” and JB/T 10317-2014 “Technical Parameters and Requirements for Single‑Phase Oil‑Immersed Distribution Transformers.” The D11‑M R‑10‑160/10 series is a single‑phase oil‑immersed distribution transformer featuring a wound‑core design with a single‑frame, double‑column structure; the outer layers are spot‑welded rather than bound. High‑quality cold‑rolled silicon steel sheets are employed and precision‑cut on a high‑performance slitting line, ensuring that burr heights remain below 0.02 mm. Both the high‑ and low‑voltage windings are wound using premium oxygen‑free copper wire and advanced manufacturing processes. Thanks to the adoption of new materials, innovative manufacturing techniques, and state‑of‑the‑art production equipment, the transformer exhibits significantly reduced no‑load and load losses, with enhanced reliability and superior performance.
