Cet article résume un guide technique basé sur les brochures Contune et destiné aux acheteurs d’équipements pour isolateurs haute tension.
Testing equipment and laboratory planning links are included where relevant.
Faits techniques utilisés
- Acoustic emission monitoring can detect micro-crack signals during each crimp.
- Live monitoring includes pressure, acoustic intensity and displacement.
- International composite insulator QC expectations are becoming stricter according to the brochure positioning.
- Crimping monitoring should be connected to final mechanical verification.
Points de sélection
Le contrôle du sertissage doit combiner pression, déplacement et inspection.
Définissez une fenêtre de process et conservez les enregistrements.
Qualité, sécurité et rapports
Les signaux anormaux doivent déclencher une inspection.
Liste de contrôle acheteur
- Pressure curve
- Displacement curve
- Acoustic emission signal
- Fitting dimensions
- Operator setup record
- Final mechanical verification
FAQ
What is the main risk in crimping?
Insufficient grip or hidden damage to the rod can both create later mechanical failure risk.
Should every crimp be recorded?
For high-traceability production, recording every cycle is preferable.
