5000V 0.18mm FIW WIRE ENAMELED COPPER WIRE INSULATED COPPER CONDUCTOR WINDING WIRE
Fully insulated (FIW) zero-defect enamelled round copper wire is the wirewith highthermal class, Zero-defect strengthened insulation and highvoltage resistance compliance with IEC60317-56 / IEC60950U and NEMAMW85-C. FIW is an alternative wire to build electronic transformerstypically using TIW (Triple Insulated Wires)The wire can meet therequirements of miniaturized components,good winding performance andlow cost, applied small transformer, electronic switch etc
FEATURES

High thermal class 180;
High break down voltage, up to 15KV;
High insulation resistance,up to 6000Vrms,1min;
Solderable at 390℃, (no need to peel insulation);
High cut-through temperature, 250℃,2s no cut through, Air Reflow ( peak temperature 260℃), no crack;
Color option:
natural(N)/red(R)/green(G)/blue(B)/violet(V)/brown(BR)/Yellow(Y);
Very good winding performance, suitable for high speed winding machine.
Min.diameter can be 0.04mm.
IMPROVED PRODUCTIVITY
Simple production processes: No barrier tape and interleaved insulation tape are required
Solderability: Soldering can be conducted without removal of insulation layer

Tianjin Ruiyuan Electric Material Co,.Ltd
Tianjin Ruiyuan Electric Material Co,.Ltd (Ruiyuan) was established
in 2002, in the past 24years, we have been committed to "Precision Engineering for Complex Wire
Solutions." This dedication has driven us to expand our product
range from fine enameled copper wires to include litz wire, OCC
copper wire, rectangular enameled copper wire, triple-insulated
wire, and guitar pickup wire. Currently, we offer six main
categories with over 20 varieties of magnet wire.
Engineering Excellence Beyond the Standard For over 24 years, Tianjin Ruiyuan (Ruiyuan) has evolved from
a specialist manufacturer of ultrafine enameled copper wire into a
strategic Solution Provider for the world’s most demanding industrial applications. We don’t
just supply wire; we engineer the critical components that drive
performance in high-frequency power electronics, aerospace, and
medical technology.
Bridging the Gap in High-Frequency Innovation In an era where efficiency is non-negotiable, Ruiyuan stands
at the forefront of tackling complex challenges in extreme insulation and high-frequency loss reduction. Our expertise is best demonstrated through our R&D
initiatives for the European automotive sector. When global Tier 1 suppliers faced the dual challenge of solvent
resistance and UL94-V0 flame retardancy for wireless charging
systems, standard solutions failed. Our engineering team delivered
a breakthrough: a specialized ETFE-extruded Litz wire that optimized thermal stability without compromising
electrical performance—a solution now in mass production for the
future of mobility.
Such case is prevalent in our company, that fully demonstrate our
advantages on technology and service Besides this, these numbers
tell more about us
- 7-10days Average delivery time.
- 90% European and North American customers. Such as PTR,ELSIT, STS
etc.
- 95% Repurchase rate
- 99.3% Satisfaction rate. Class A supplier verified by German
customer.
Your Strategic Partner for Extreme Applications From 0.012mm ultra-fine enameled copepr wire to complex rectangular
Litz wires, we provide the technical depth required to push the
boundaries of what’s possible. Whether you are optimizing an EV
drivetrain or developing next-gen power conversion, Ruiyuan is your
partner in achieving unparalleled electromagnetic efficiency.
