FAQ
Q1: What makes your colored PI tape technology special?
A: Our proprietary colored PI tape maintains color integrity at 300℃+, where conventional markings would fade or degrade. This provides reliable conductor identification throughout the cable's service life in extreme temperature applications.
Q2: Why use nickel-plated copper instead of tinned copper?
A: Nickel plating provides superior high-temperature performance - it withstands temperatures up to 600℃ without oxidation, offers better corrosion resistance in harsh environments, and maintains stable electrical properties at extreme temperatures where tin would melt or oxidize.
Q3: How does this cable achieve low outgassing properties?
A: Polyimide is inherently low-outgassing, and our manufacturing process minimizes contamination. The cable typically achieves TML ≤1.0% and CVCM ≤0.1% when tested per ASTM E595, making it suitable for vacuum and space applications.
Q4: What radiation resistance does this cable offer?
A: PI insulation maintains properties after exposure to significant radiation doses (typically up to 10⁸-10⁹ rads depending on specific formulation), making it suitable for nuclear, space, and medical radiation applications.
Q5: Can custom configurations with different conductor counts be produced?
A: Yes, we offer various custom configurations including different conductor counts (2-20+), alternative shielding options, specialized jacketing, and custom colored PI tape coding to meet specific application requirements.
