Litz Wire (Flat Wire)

Litz Wire (Flat Wire)

Our litz wire is constructed from fine insulated copper strands arranged to minimize eddy-current losses at high frequency. The flat-wire arrangement can be shaped to fit flat or rectangular winding slots, improving space utilization in compact coils. It is suitable for high-frequency inductors, transformers, wireless charging coils, OBC/DCDC converters and induction heating applications. Jintian supplies magnet wires backed by ISO 9001, ISO 14001 and IATF 16949 certified quality systems. Contact us for litz wire specifications and custom constructions.

Enameled Wire FAQs

  • Is enameled copper wire conductive?

    Copper is the standardly used conductor material for enameled wire with excellent conductivity and very good winding ability. Enameled Copper Wire, otherwise known as magnet wire, is a highly versatile material used principally in applications that require electrical transference including transformers, inductors, motors, generators, speakers, hard disk actuators, electromagnets and other applications that require tight coils of enamel insulated copper wire. Copper's highly conductive properties make it the perfect metal for electrical applications, and it can be fully annealed and electrolytically refined to allow closer winding for electromagnetic coils. By coating the wire with insulation – typically one to four layers of polymer film – the flat enameled copper wire is protected from contact with its own and other wires'electrical currents, preventing short circuits from occurring and extending the longevity, efficiency and applications for the wire.

  • What is an enamel wire made of?

    Enameled wire is a main type of magnet wire, which consists of two parts: the conductor and the insulating layer. The bare copper wire for sale is annealed and softened, then painted and baked for many times.  The conductor shall be copper wire, oxygen free copper wire and low-oxygen copper wire with smooth surface, roundness, uniform quality and no defects as specified in the specified standard. The copper wire is coated with continuous and smooth synthetic resin without foaming and other impurities. Magnet wire insulating films mainly use (in order of increasing temperature range) polyvinyl formal (Formvar), polyurethane, polyamide, polyester, polyester-polyimide, polyamide-polyimide (or amide-imide), and polyimide, to achieve different technical standard.
