ZTELEC focuses on providing stable and reliable one-stop insulation material solutions for medium and large industrial motors. Its products are widely applied in winding insulation, slot insulation, phase-to-phase insulation, and structural support components.
The materials feature excellent electrical insulation, high mechanical strength, superior thermal resistance, and strong aging resistance, enabling them to meet the demanding requirements of industrial motors operating under high loads, continuous duty, and complex working conditions.
Common Insulation Materials for Industrial Motors
| Application Area | Common Insulation Materials | Main Functions & Characteristics |
| Slot Insulation | DMD, NMN, NHN insulation paper | Electrically isolates windings from the stator core, prevents ground faults, and provides good thermal resistance and mechanical flexibility |
| Turn-to-Turn Insulation | Polyester film, Polyimide (PI) film, DMD | Prevents short circuits between winding turns; requires high dielectric strength and heat resistance |
| Phase-to-Phase Insulation | DMD, NMN, NHN, NOMEX® | Prevents electrical discharge or breakdown between different phases; suitable for medium- and high-voltage motors |
| Winding Taping / Banding | Fiberglass tape, Polyester fiber tape | Secures windings, improved mechanical strength, and offers thermal resistance |
| Structural Support Insulation | FR4 / G10 / G11 epoxy fiberglass | Used for structure supports and insulating spacers; high mechanical strength and excellent dimensional stability |
