What Is PEEK Insulated Cable?
PEEK (Polyether Ether Ketone) insulated cable is a high-performance wiring solution designed for extreme environments. PEEK is a semi-crystalline, high-temperature thermoplastic polymer known for its outstanding mechanical strength, thermal resistance, and chemical stability. When used as cable insulation, it provides a lightweight yet durable alternative to traditional materials, including mineral-insulated (MI) cables.

Key Features and Properties
High Temperature Resistance: Withstands continuous operation up to 260°C, making it suitable for high-heat environments.
Mechanical Strength: Excellent tensile and compressive strength ensures long-term durability under stress and vibration.
Chemical Stability: Resistant to solvents, oils, acids, and radiation, ensuring reliable performance in corrosive or high-radiation areas.
Lightweight Alternative: Provides a weight advantage compared to mineral-insulated cables, which is critical in aerospace and mobile systems.
Radiation Resistance: Exceptional tolerance to gamma and electron-beam radiation, making it ideal for nuclear and medical applications.
Advantages of PEEK Insulated Cables
Extended Service Life in harsh operating conditions.
Reduced System Weight compared to MI cables, lowering overall installation load.
Enhanced Safety due to flame resistance and low smoke/toxic emissions.
Design Flexibility: Available in custom sizes, conductor materials (copper, nickel, silver-plated), and shielding configurations.
Applications of PEEK Insulated Cables
PEEK cables are widely adopted in industries where reliability under extreme conditions is critical:
Nuclear Facilities: Withstands high radiation and extreme heat in nuclear power plants and research reactors.
Medical Equipment: Used in MRI, X-ray, and radiation therapy devices where radiation and chemical resistance are essential.
Aerospace Industry: Provides lightweight, durable cabling solutions for satellites, spacecraft, and aircraft.
Oil & Gas Exploration: Suitable for downhole sensors, drilling equipment, and environments exposed to high pressure and corrosive fluids.
Military & Defense: Performs reliably in harsh battlefield environments and high-performance defense systems.
Why Choose PEEK Over Mineral-Insulated (MI) Cable?
Weight Savings: PEEK insulation significantly reduces cable weight.
Flexibility: Easier to install and route compared to rigid MI cables.
Comparable Performance: Delivers similar heat and radiation resistance while offering enhanced design versatility.
