ETFE power cables are designed for high-performance electrical applications where temperature resistance, mechanical strength, and chemical durability are critical.
ETFE, short for Ethylene Tetrafluoroethylene, is a fluoropolymer insulation material known for its excellent dielectric properties and lightweight toughness, making it ideal for aerospace, defense, industrial, and automotive power systems.

ETFE Power Cables
If you need cables that withstand high heat, radiation, and harsh chemicals without compromising performance, ETFE insulated cables are the perfect choice.
What Is an ETFE Power Cable?
An ETFE power cable is an electrical cable that uses ETFE as insulation or jacket material to protect the conductor.
Compared to conventional PVC or XLPE cables, ETFE cables deliver superior electrical stability, temperature endurance, and mechanical strength in a much lighter form factor.
Typical Construction
Conductor: Tinned copper, silver-plated copper, or nickel-plated copper
Insulation: ETFE (Ethylene Tetrafluoroethylene) fluoropolymer
Shielding (optional): Braided tinned copper or aluminum foil
Jacket (optional): ETFE or cross-linked fluoropolymer
Key Features and Advantages
