FAQ
Q1: What makes Polyimide (PI) capable of 300℃ operation?
A: PI has an exceptionally high glass transition temperature and thermal decomposition point, maintaining mechanical and electrical properties at temperatures where most polymers would melt, decompose, or become brittle. Its molecular structure provides outstanding thermal stability.
Q2: How does wrapped PI insulation compare to extruded alternatives?
A: Precision-wrapped PI provides more consistent thin-wall insulation (as thin as 0.025mm) than extrusion, allowing for smaller OD while maintaining dielectric strength. The wrapped construction also offers better flexibility retention at extreme temperatures.
Q3: Can this cable withstand thermal cycling between extreme temperatures?
A: Yes, PI maintains excellent flexibility and adhesion through repeated thermal cycling from cryogenic temperatures to 300℃+, making it ideal for applications experiencing wide temperature fluctuations.
Q4: What are the current carrying capabilities at 300℃?
A: Current rating decreases at elevated temperatures. At 300℃, derating is typically 50-60% of room temperature capacity. Our engineering team can provide specific derating curves for your application conditions.
Q5: Is this cable suitable for high-vibration environments?
A: Absolutely. The combination of fine-stranded conductors and tough PI insulation makes this cable exceptionally resistant to vibration fatigue, which is why it's widely used in aerospace and automotive applications.
