PEEK cable, also known as polyether ether ketone (PEEK for short) is an all-aromatic semi-crystalline thermoplastic polymer, due to the macromolecular chain containing rigid benzene rings, soft ether bonds and carbonyl group that improves intermolecular forces, structural regularity, and thus has a unique performance, it is a special kind of polymer material, known as the tip of the pyramid of the plastics industry. It is a kind of cable using polyether ether ketone as insulation material or sheath material. It has the advantages of high heat-resistant grade, radiation-resistant, chemical-resistant, high impact strength, good abrasion and fatigue-resistant, flame retardant, excellent electrical performance, etc. It can meet the demanding requirements for cables under special conditions.
PEEK cable structural design
Conductor: Tinned copper or bare copper is usually used as the conductor to improve electrical conductivity and corrosion resistance.
Insulation: PEEK cable is used as the insulating material to provide good electrical and mechanical protection.
Sheathing layer (optional): As required, a sheathing layer can be added on the outside to improve protection.
PEEK Cable Core Benefits
PEEK cable AK250 300VMaterials with optimal radiation resistance
Best performing low smoke, halogen free material with a wide temperature range (-200ºC to +260ºC)
Excellent resistance to water, fire, smoke and chemicals
Flexibility: able to withstand frequent bending and vibration.
Basic characteristics of PEEK cables
High temperature resistance: PEEK insulation has excellent heat resistance and can work continuously at temperatures up to 260°C.
Flame retardant: PEEK material is not easily combustible and complies with UL 94 V-0 flame retardant rating, which can effectively prevent the spread of fire. Even in high-temperature environments, it can continue to remain stable.
Chemical resistance: PEEK has excellent chemical resistance and is suitable for a variety of harsh environments.
Mechanical Strength: PEEK material has high strength and abrasion resistance, ensuring that the cable remains robust and durable under complex conditions.
Electrical insulation: PEEK provides good electrical insulation to ensure the stability and accuracy of signal transmission.
Biocompatibility: PEEK materials are harmless to the human body and are suitable for medical devices and implants.
Lightweight: The lightweight nature of PEEK material reduces the overall weight of the cable.
PEEK wire and cable application areas
Aerospace: Ultra-high temperature wire for aircraft and spacecraft.
Oil industry: as winding wire and connecting wire for submersible oil pump motors, maintaining performance at extreme temperatures.
Wind power station/atomic power plant: used for winding coils in wind farms and nuclear island drive mechanisms, capable of long-term use under irradiated conditions.
Naval industry: seawater resistance and lightweight design make it widely used in ships.
High-speed traction locomotives: suitable for high-speed trains and other transportation equipment.
Automotive manufacturing: PEEK cable materials are used in automotive electronic systems due to their strength, durability and heat resistance.
Oil and gas: Used in antenna casings, valve seats, electrical connectors and more, capable of handling extreme temperatures and high-pressure environments.
Military, semiconductor and electronics: PEEK is used as an electrical insulator and mechanical component for semiconductor production and electronic devices.
PEEK wire in two forms: PEEK insulated wire/PEEK high bonding wire.
TST CABLES’ PEEK wire products are available in two forms: PEEK insulated wire (round/flat cable) and PEEK highly bonded wire, which are ideally suited for electric motors, generators, transformers, solenoids, and other electromechanical equipment where superior performance in harsh environments is critical.
PEEK Insulated Wire
250℃ PEEK Single-core Multi-core Cable
PEEK insulated wire has been developed for challenging environments such as the oil and gas, aerospace, and electrical industries.PEEK insulated wire has excellent abrasion resistance and is able to withstand strong pressures and corrosive fluids. For some applications, little or no varnish is required and slot liners may not be needed.PEEK insulated wire is best suited for applications that do not require hairpin windings, such as solenoids.
PEEK insulated wire is available in insulation thicknesses ranging from 0.001 inches (0.025 mm) to 0.080 inches (2.032 mm) in U.S. Wire Gauge (AWG) sizes #3 to #40.
PEEK High Bonding Wire (PEEK HB Wire)
PEEK High Bond Wire is a wire that uses PEEK material as the insulating layer and has a special process or adhesive added during the manufacturing process to enhance the bonding between the conductor and the insulating layer inside the wire.
PEEK Wire High Bond (PEEK HB Wire) offers higher performance than our normal standard PEEK insulated wire. As a single-ply solution, PEEK Wire HB allows motor designers to optimize insulation thickness and improve the PDIV performance of enameled wires, guiding the way for next-generation motor designs in harsh environments. As a single-layer, 100% PEEK solution, PEEK HB wire is ideally suited for applications that require tight bend radii, such as axial flux motors with hairpin windings, and TST CABLES’ patented extrusion technology provides excellent adhesion and bonding of the PEEK coating to the underlying conductor, allowing the wire to be flexed and wound with less risk of delamination.
PEEK HB wire is available in insulation thicknesses ranging from 0.001 inches (0.025 mm) to 0.015 inches (0.381 mm) in U.S. wire gauge (AWG) sizes #8 to #26.
PEEK Wire and Cable Standards and Testing
UL 758: Standard applicable to flexible cables for domestic and commercial electrical appliances, although PEEK cables are mainly used for industrial and special applications, they still need to comply with the relevant standards.
