PEEK Multi-Core High Temperature Shielded Cable | 4x20AWG SPC/PEEK/SCR/PEEK 300℃ 500V

PEEK MULTI-CORE HIGH TEMPERATURE CABLE: ENGINEERED FOR THE EXTREME FRONTIER

Our PEEK Multi-Core High Temperature Cable is engineered to deliver unparalleled performance in the most thermally demanding and chemically aggressive environments on Earth and beyond. This advanced cable features 4x20AWG silver-plated copper (SPC) conductors with 19/0.18 fine stranding, each insulated and protected by multiple layers of PEEK (Polyetheretherketone), a premium semi-crystalline thermoplastic. Encased by an SPC wire braid shield (≥85% coverage) and an overall PEEK sheath, it is rated for 500V and continuous operation up to 300℃ (tested at 320℃ for 8 hours). It is the definitive solution for aerospace, downhole instrumentation, advanced propulsion, and chemical processing where failure is not an option.

KEY FEATURES & TECHNICAL ADVANTAGES

✔ Ultimate Thermal & Chemical Stability: PEEK construction maintains mechanical integrity and dielectric strength from cryogenic temperatures to a continuous 300℃, with exceptional resistance to hydrolysis, acids, bases, and hydrocarbon fluids.
✔ Superior EMI Shielding & Signal Integrity: SPC wire braid shield (≥85%) provides robust protection against electromagnetic interference, while the low-loss PEEK dielectric ensures clean signal transmission for sensitive instrumentation.
✔ Exceptional Mechanical Durability: PEEK offers outstanding abrasion resistance, cut-through performance, and maintains high flexibility even after prolonged exposure to extreme heat, outperforming PTFE or FEP in dynamic applications.
✔ Space & Weight Optimized: A compact 4.5mm OD enables high-density wiring in confined spaces, such as aircraft engine bays or downhole tool strings, without compromising performance.
✔ Rigorous Quality Validation: Each cable batch is subjected to a 1.5kV/min hi-pot test and a 320℃/8-hour thermal endurance test, guaranteeing reliability under extreme operational stress.

FAQ

Q1: What makes PEEK superior to PTFE or FEP for high-temperature applications?
A: While PTFE and FEP have good temperature ratings, PEEK offers far superior mechanical strength, abrasion resistance, and cut-through resistance at high temperatures. It does not cold-flow under pressure like PTFE and maintains its shape and properties better in dynamic, high-stress environments.

Q2: Why is silver plating used on both the conductor and shield?
A: Silver plating provides the highest electrical conductivity and superior corrosion/oxidation resistance at extreme temperatures compared to tin or nickel. This is critical for maintaining signal integrity and shielding effectiveness in harsh, high-temperature environments over the long term.

Q3: Can this cable withstand thermal cycling and vibration?
A: Absolutely. PEEK has excellent resistance to thermal fatigue and creep, making it ideal for applications with rapid temperature swings. Combined with the fine-stranded conductors, the cable is designed to withstand significant vibration, which is why it is specified for aerospace and downhole tools.

Q4: Is the cable suitable for use in vacuum or radiation environments?
A: Yes. PEEK has very low outgassing properties, making it suitable for vacuum chambers and space applications. It also exhibits good resistance to gamma radiation, outperforming many other polymers in nuclear or space environments.

Q5: Can you customize the shielding or add individual pair shields?
A: Definitely. We can engineer this cable with various shielding configurations, including individual pair shielding (foil or braid) within the overall construction, tailored to your specific EMI/RFI requirements.
