PTFE Insulated Wires, Cables & Sleeves

Tefkot Cable Company offers PTFE (poly tetra fluoro ethylene) Insulated Wires, Cables and Sleeves. PTFE is a thermoplastic having outstanding dielectric properties and other such inherent physical and chemical properties, which establishes this insulating material as one of the best amongst available ones. PTFE wires and cables have many advantages: suitable for use at temperatures ranging from -65°C to +200°C for silver plated and -65°C to +260°C for nickel plated wires and for very wide frequency range (DC to 10000 MHz); fire retardant and inert to almost all chemicals even at elevated temperatures; smaller in size, more flexible; lighter in weight and higher reliability; lowest dielectric constant (2.1); dissipation factor (below 0.0003); excellent flex life and totally unaffected by outdoor exposure to unlimited period; non contaminating, non toxic and bio compatible with good mechanical strength; and resistant to fair corona, cold flow, cut through, ultra radiation, fungus and mould growth. The company manufactures various types of wires, cables and sleeves having PTFE insulation. Conductor used is of electrolytic grade pure copper either bare or with silver/nickel plating, in single (solid) or in strain free true concentric, 7, 19 or 37 strand or in bunched construction as per customer requirement. The insulation is of tape wrapped and sintered PTFE. Advantages over extruded wires: due to the unique tape wrap insulation process used in making PTFE wire, remarkable perfect concentricity is obtained which normally is not possible in extruded wire. These wires contain better stripping, better flexibility, better tear resistant and dielectric strength than extruded wires due to tape wrap technique process. PTFE insulated wires conform to MIL-W 16878, JSS-51034 and other standards as per customers need.
