Served Litz Wire

Served Litz Wire

Served litz wire refers to an electromagnetic wire formed by wrapping one or two layers of natural or chemical fibers over the surface of an enameled stranded wire, including polyester silk-covered litz wire, nylon silk-covered wire, and self-adhesive silk-covered wire (acetone-bonded, hot-air-bonded).
Taped Litz Wire

Taped Litz Wire

Taped wire is an electromagnetic wire formed by wrapping a layer of Mylar film or other material film over the surface of enameled stranded wire with a certain overlap ratio.
LITZ WIRE

LITZ WIRE

Enameled stranded wire, also known as Litz wire (derived from the German word "Litz"), is an electromagnetic wire formed by twisting multiple strands of enameled single wires together. Enameled stranded wire can effectively reduce the "skin effect" in high-frequency applications, minimizing high-frequency current loss. Compared to single-strand wires of the same cross-sectional area, enameled stranded wire can lower impedance, increase conductivity, improve efficiency, and reduce heat generation, while also offering superior flexibility. It is widely used in electronic components for high-frequency applications such as high-frequency transformers and high-frequency coils.
Extruded Litz Wires

Extruded Litz Wires

LITZ wires with an extruded layer can improve flexibility, mechanical strength, chemical resistance, and breakdown voltage. Compared to conventional structures, the bending lifespan of extruded wires is also significantly enhanced.Hongtong Company currently focuses on extrusion production lines, including nylon extrusion lines, self-adhesive film-covered wires, and self-adhesive silk-covered wires.
