When Standard Wire Fails at High Temperature
In industrial furnaces, servo motor cabinets, and injection molding machines, conventional PVC or silicone wires degrade above 150°C. Insulation cracks, conductors oxidize, and unexpected downtime follows. For engineers specifying wiring in sustained 180–200°C environments, the wire must hold up — not just pass a one-time test.
DYDEN Japan 4-Core 5.5mm² Teflon-Core Wire — Built for Sustained Heat
This DYDEN Japan high-end capillary wire uses PTFE (Teflon) insulation over tin-plated copper conductors. Four cores, each 5.5mm², bundled in a compact capillary layout designed for tight routing in machinery panels, robot arms, and heating equipment. The tin plating resists oxidation even in humid or chemically aggressive workshops. DYDEN manufactures this wire to Japanese industrial standards — consistent diameter, uniform insulation thickness, and reliable pull strength batch after batch.

Why This Wire Performs Where Others Don’t
1. Continuous 200°C rating — not peak, not intermittent. PTFE insulation maintains dielectric strength at 200°C without softening or off-gassing. In conveyor ovens and die-casting machines where ambient heat sits at 170–190°C for 12+ hour shifts, this wire stays flexible and electrically stable.2. Tin-plated copper resists the workshop, not just the heat. In food processing, plating, or chemical plants, moisture and mild corrosives attack bare copper fast. Tin plating adds a barrier layer — lower contact resistance over time, easier soldering during assembly, and no green corrosion on connector terminals.3. Capillary 4-core layout saves panel space. Four 5.5mm² conductors in one compact jacket replace four separate cables. This cuts conduit fill, reduces connector count, and shortens assembly time in servo motor drives, robotic joint wiring, and multi-axis CNC control cabinets.4. Consistent pull strength from DYDEN’s Japan production line. Capillary wires are prone to core-to-core adhesion issues if extrusion pressure varies. DYDEN controls this tightly — you get smooth stripping, no core damage during pull-in, and predictable bend radius in repeated flex applications like drag chains.
Suitable Industries & Applications
