ASA Electrical Insulation Performance
Problem Phenomenon
【Problem Phenomenon】Electrical parts need both insulation and weather resistance, evaluating ASA electrical performance
Cause Analysis
ASA has high volume resistivity, good dielectric strength and low water absorption, wet-state insulation is stable; outdoor electrical insulation is a natural fit; during on-site troubleshooting, verify item by item according to this mechanism, avoid blindly adjusting the machine based only on experience
Solution
Insulation parts select grades by CTI and dielectric strength; wet-state insulation verification; flame retardant requirements superimpose UL grades; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ASA wet-state insulation is stable, outdoor electrical parts are naturally suitable; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
