Enameled Wire, High Frequency Leeds Line, Extruded Leeds Line Manufacturer & Supplier

ABOUT US

Since 2004, our company has been deeply engaged in the field of enameled magnet wires and has continuously expanded its production scale. Currently, we have two major production bases. One is located in Cangqian, the western suburbs of Hangzhou, and the other is situated in the Economic and Technological Development Zone of Xuancheng, Anhui Province.In 2023, our company established the New Energy Wire Business Division, focusing on the development of combined insulated wires. Our company has successfully passed the IATF16949 and ISO9001 quality system certifications, and has obtained a number of patent certificates. With the triple certifications of UL, ROHS environmental protection, and REACH, we safeguard the product quality. We provide core support for the winding systems in global fields such as new energy vehicles, high-end medical equipment, 5G communication, and industrial automation.

HONOR CERTIFICATES

Our company places quality at the core and adheres to the philosophy that "Quality is forged by certification, and the future is defined by patents". From the copper core to the coating, every single meter of wire embodies our unrivaled dedication to quality.
Regarding quality management, our company has attained the IATF16949 automotive - grade certification, securing access to the supply chains of the world's top 10 automotive manufacturers. With ISO 9001 Quality Management System certification, we execute comprehensive process - based quality control. Our wires have been granted the UL certification (Certificate No. E326617), are fully RoHS - compliant with zero detection of hazardous substances, thus satisfying the stringent requirements of the European Union.

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.
