Aramid Paper Wrapped Aluminum Round Wire

What is Aramid Paper Wrapped Aluminum Round Wire? ‌

Aramid Paper Wrapped Aluminum Round Wire is a composite wire with an aluminum core wrapped in aramid paper, known for its lightweight, high strength and high temperature resistance. Its structure uses aluminum core for conductivity (50% lighter than copper), aramid paper for insulation (resistant to 220℃ high temperature), and resin bonding layer for peeling resistance. The strength is far superior to steel wire and it does not burn when exposed to fire. It is mainly used in electric vehicles (weight reduction and endurance increase), aircraft wiring harnesses (extreme temperature resistance) and industrial robots (fatigue-resistant wiring).

‌Advantages of Aramid Paper Wrapped Aluminum Round Wire‌

• ‌ Lightweight‌: The density of aluminum is only 30% of that of copper, which is suitable for weight reduction areas such as automobiles and aircraft. New energy vehicles use it to replace copper wire, and the wiring harness reduces weight by 18% and increases endurance by 5%.
• ‌ High temperature resistance‌: Long-term temperature resistance of 220℃ (short-term 400℃), while ordinary plastic cables (such as PVC) can only withstand 105℃.
• ‌ High strength‌: The tensile strength of aramid fiber is 5 times that of steel wire, and it can withstand bending for more than 100,000 times, solving the problem of easy breakage of aluminum wire.

Application fields of Aramid Paper Wrapped Aluminum Round Wire‌

• ‌ Aerospace‌: Used for rocket engine wires and aircraft sensors, resistant to extreme temperatures of -60℃~300℃.
• ‌ New energy vehicles‌: Used for drive motor windings and battery connection wires, 40% lighter than copper wires.
• ‌ Power equipment‌: Used for transformer and reactor coils, with a lifespan of up to 30 years.
• ‌ Industrial robots‌: Robot arm joint wires, 0.5mm thin wires can be bent 100,000 times without breaking.
