Hot Elongation Test Apparatus

Why Hot Eloangation Testing is Required?

Hot Eloangation test is used to check the degree of cross - linking in thermoset materials like XLPE insulation.
Poor cross - linking leads to hidden failures that appear only during operation.

  • Verify proper curing of insulation
  • Ensure dimensional stability at high temperature
  • Avoid deformation under mechanical load
  • Maintain consistent cable quality

Acceptance criteria (As per Standards)

  • Elongation ≤ 175%
  • Permanent Set ≤ 15%

Why Hot Elongation Testing is Critical

  • Ensures Insulation can withstand high-temperature conditions
  • Confirms proper cross linking of material
  • Prevents failure in real operating environments
  • Helps meet IEC & IS quality standards
  • Reduces product rejection and costly rework
  • Enhances overall cable reliability and safety
