DMD / DMDD Cables are high-performance insulation cables constructed using multiple layers of polyester film and non-woven polyester fabric, bonded with high-grade resin to form a composite insulation material. These cables are engineered to provide superior dielectric strength, thermal endurance, and mechanical integrity, making them ideal for low to medium voltage electrical windings. The DMD (Class B - 130°C) and DMDD (Class F - 155°C) insulation systems offer excellent resistance to thermal aging, moisture, and mechanical stress, ensuring reliable operation in motors, transformers, and electrical apparatus even under continuous load conditions.

Manufactured on advanced high-speed production lines at Harnawa and subjected to rigorous quality control—covering incoming materials, in-process monitoring, and 100% high-voltage inspection—these cables are guaranteed to be defect-free throughout their service life. Their consistent quality and reliability make them a trusted choice for use in transformer winding, electric motor insulation, lighting ballasts, and other electromagnetic applications. Widely adopted in the power, automotive, and industrial sectors, DMD/DMDD Cables deliver long-term electrical insulation performance, while supporting energy-efficient and compact winding designs.
