Enamelled wire elongation and tensile-strength comparison

Heating temperature and bonding-strength chart — Select the insulation class according to coil temperature rise and operating conditions. For conventional conditions with an 80–120 °C temperature rise, Class 130–180 is recommended; high-load applications such as automotive hydraulic systems require heat-resistant products rated Class 180 or above. Correct class selection improves coil durability and extends service life.
