FTIW-F 0.15mm ETFE Insulation Triple Insulated Wire
This is a triple-insulated wire with a diameter of 0.15 mm. Using ETFE (ethylene tetrafluoroethylene) insulation, this conductor offers superior performance, making it ideal for a wide range of demanding applications.
ETFE is a high-performance fluoropolymer renowned for its exceptional mechanical strength, chemical resistance, and thermal stability. It is a copolymer of ethylene and tetrafluoroethylene, a material that is not only tough but also versatile. ETFE's high impact resistance, compressive strength, and abrasion resistance make it superior to many other fluoropolymers. These properties are crucial for applications requiring extremely high durability and reliability.
We support small batch customization with a minimum order quantity of 3,000 meters. Additionally, we offer ETFE insulated litz wire, with the size and number of strands tailored entirely to your specifications.
In the industrial sector, silk covered litz wire has proven to be a valuable asset due to its high frequency effect. The wire's design contains multiple individually insulated strands, which reduces the skin effect and ensures that current is evenly distributed throughout the wire. This property makes silk covered litz wire an excellent choice for applications requiring high-frequency signals, such as inductors, transformers and other electronic components used in industrial machinery and equipment. The wire's ability to handle high-frequency currents with minimal power loss makes it an important component in a variety of industrial environments where efficiency and reliability are critical.
For motors and transformers, silk covered litz wire offers unparalleled performance. The unique construction of this wire, typically composed of multiple strands of enameled wire, provides excellent electrical conductivity and minimizes skin effect, making it ideal for winding coils in motors and transformers. Using silk covered litz wire in these applications ensures even current distribution, reduces power losses and increases the overall efficiency of the motor or transformer. Additionally, the wire's ability to withstand high-frequency currents makes it a first choice for high-performance motors and transformers used in industrial and commercial environments.
