Professional Performance Features
-
Advanced Tape Wrapping Technology: Unlike common extruded wires, our PTFE tape wrapped and sintered insulation provides a more compact, uniform dielectric layer with superior resistance to mechanical stress and cut-through.
-
Silver-plated Copper Advantage: The silver-plated conductor option ensures maximum conductivity and eliminates oxidation at sustained temperatures up to +250°C (482°F), essential for high-reliability aerospace avionics.
-
600V Safety Margin: Engineered with an increased insulation wall (0.25mm) compared to standard 250V wires, providing a robust safety factor for higher-power internal equipment connections.
-
Chemical & Environmental Inertness: Fully resistant to all common aviation hydraulic fluids, fuels, lubricants, and corrosive cleaning agents. The PTFE material is inherently non-aging and UV stable.
-
Flexibility & Weight Saving: The stranded conductor structure allows for a very tight bend radius, making it ideal for high-density wiring harnesses in cramped electronic enclosures without adding significant weight.
Material Guide for Customers
-
Bare Copper: The standard choice for general-purpose high-temperature applications up to +200°C (392°F).
-
Silver-plated Copper: Recommended for extreme environments up to +250°C (482°F) or where high-frequency signal integrity is a priority.
-
PTFE Wrapping: A specialized manufacturing process that results in a denser and more flexible insulation compared to standard plastic extrusion.
