Tulsa Power Inc utilises the latest 3D engineering software and specialises in custom designed systems built to the customer’s requirements and specifications.

abrasion. Unlike thermoplastic materials such as PFA, PTFE does not melt and resists a soldering iron, even at 350°C. PTFE also allows for very thin insulation thicknesses compared to silicone insulated wires. PTFE-insulated bare copper wires are an ideal solution for applications working under 200°C, such as electrical appliances (ovens, cooking plates and boiler burners, for example) and automotive engines.

Axon’ process enables extruded PTFE to be applied to a conductive copper core without damaging the surface of the conductor. This avoids oxidation and helps preserve the qualities of copper to ensure good connections. Previously, a manufacturing process that did not oxidise copper has only been used with bare copper wires insulated with silicone or thermoplastic insulating materials such as perfluoroalkoxy (PFA). The new Axon’ process provides a more economical alternative to bare copper wires insulated with PFA, as PTFE is cheaper than PFA, while offering the same heat performance. The other major advantage of the process is that it does not require silver or nickel-plating on copper to protect the conductor from oxidation. PTFE not only offers good electrical insulation, but it also affords very good chemical resistance. PTFE is chemically inert and self-extinguishing; it also resists Cable’s patented
