IS 13730/IEC 60317 PART-8/180°C
Engineered to endure the harshest operating environments, our Vidya Hermetic Class-H Enamelled Wires deliver rugged durability and extreme thermal resistance. This specialized winding wire is purpose-built for heavy-duty machinery and sealed refrigeration systems where standard insulation fails. By combining ultra-pure copper core conductivity with advanced chemical resilience, Vidya provides industrial manufacturers with a reliable, burnout-resistant solution for high-stress electrical assemblies.

Quality Maintain Every Time
Every batch undergoes specialized industrial testing protocols tailored for aggressive environments. We subject our hermetic wires to strict refrigerant resistance checks (R22/R134a/R410a compatibility), heat shock testing at temperatures exceeding 200°C, and high-voltage dielectric breakdown assessments. Our specialized baking control guarantees a smooth, pinhole-free enamel coating that maintains a zero-defect standard, ensuring that the wire never strips, flakes, or cracks under heavy mechanical winding stress.
Thermal Endurance under Extreme Heat
Shield your electrical equipment from catastrophic thermal burnout. Formulated with a modified polyesterimide baseline, these Class-H wires comfortably manage continuous operating temperatures up to 180°C and handle sudden, high-amp peak temperature spikes without losing insulation integrity. This superior thermal profile significantly extends the operational lifespan of heavy-duty motors and high-voltage equipment running under continuous, full-load factory conditions.
Unmatched Freon and Chemical Resistance
Specifically engineered for sealed, closed-loop machinery, the unique chemical composition of this enamel offers exceptional resistance to refrigerants, compressor oils, and aggressive solvents. Standard wires rapidly degrade and blister when submerged in harsh cooling fluids, but Vidya Hermetic wires maintain their molecular bond. This makes them the ultimate choice for refrigeration compressors and submersible pumps where the wire directly contacts liquid chemicals.
High Tensile Flexibility for Complex Machinery
Say goodbye to insulation cracking during tight, high-torque winding patterns. Our advanced drawing process ensures the copper conductor offers maximum ductility, allowing it to bend sharply into compact motor slots without micro-fracturing. The tough, slippery outer enamel layer reduces friction on automatic winding lines, accelerating your assembly speeds, preventing scrape damage, and ensuring a uniform, dense coil fill factor.
