PCABS Photovoltaic Junction Box
Problem Phenomenon
[Problem Phenomenon] Photovoltaic junction boxes require flame retardancy, weather resistance, insulation, and dimensional stability
Cause Analysis
Flame-retardant weather-resistant PC/ABS is used for photovoltaic junction boxes: V-0 flame retardancy, weather resistance, insulation, low water absorption and dimensional stability; 25-year life requirement; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Select flame-retardant weather-resistant PC/ABS for photovoltaic boxes; verify CTI and insulation; evaluate life with aging data; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PC/ABS photovoltaic boxes are flame-retardant, weather-resistant, and insulating, lasting 25 years; 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 similar problems in the future
