Litz Wire & Cable Manufacturing for "Wireless Power & Induction Heating" in Korea since 1990
< from very fine size(48 AWG, 0.030mm) to Thickest size (more than 100mm OD, approx. 8,000㎟ ) >

We design the construction and provide you solutions.

We, YDK Inc., have built various kinds of Litz Wires from thin size of 0.030mm x 10 to 192,500 stranded(27,500 strands with Teflon x 7 bundles and make a cable extruded by non-flammable PVC 105℃) and of thickest size of 0.100mm x 64,500 stranded with Kapton or XLPE. Also rectangular type is available. Namely, very fine size, 0.030mm(48AWG) to 100mm outer diameter size, 8,000㎟. We can provide you Nylon(polyamid yarn) served, Kapton(polyimide film), Nomex(aramide paper), Teflon extrusion, Natural Silk(Mulberry, Silkwarm, Cocoons), Natural Cotton, XLPE, PVC, Mylar and Dacron type using our up-to-date manufacturing facilities. Also, depending on each customer’s needs, our R&D dept. have developed new design cables and wires. FYR, YDK litz-wires have been used in many fields for maximizing efficiency. A lot of companies, government-affiliated organizations and institutes have requested us to develop new design litz wires and cables for applying their own new products. It makes us we get much more technique and skills than before. It has already been 27 years.

Litz wires are very useful conductors to reduce AC losses in high-frequency winding.

The top priority of litz wire regarding the design is the operating frequency. Operating frequency will be used to determine the size of each strand of litz wire construction, as well as affect the actual construction of the copper magnet wire. Litz construction is indicative of the skin effects, due to the limitations of number of stranding. Higher frequency ranges of litz-wire demand more strands of a thinner size gauge than same cross sectional area but consists of fewer and larger strands. Polyurethane or polyester coated material shields low electrical losses and solderability of ease, because each strand insulation typically used in enamels and polyurethanes. In addition , other insulation are also available such Nomex, Kapton, Dacron, Mylar, Silk, Teflon, Polyolefin etc. In most cases, the litz wire is wrapped by nylon single or double served, of a textile yarn as well as unserved available. The breakdown voltage or the protection of the environment should be satisfied with customers’ special requirements and special film coatings on each individual strand are available as well as double and even triple insulation overall to meet the demands of UL and IEC regulations.

Litz Wire has the following advantages :
– High efficiency
– Downed operating temperature
– Reduced footprint of the final product
– Significant weight reduction.
– The avoidance of “Hot spot”
– Relief of skin and proximity effects
– Minimum eddy-current losses.

Use of YDK Litz cables
– Litz Cables are used for all electrical coils requiring a low level of losses when alternating currents go through them.
– The range of frequency for which YDK Litz Cables necessary is very infinite : from a few hundred Hertz (Induction Heating Transformers, VLF Radar) to many Mega-Hertz (Pulse Transformers).

Magnet wire films are in business in order to meet these different needs, film, fiber, tape wrap, and a wide range of extruded insulation. A round, square and rectangular shape are manufactured to meet the requirements. Litz wire manufacturer, Y D Kim Int’l Inc., has accumulated lots of technologies as well as had rich experiences regarding design solutions with very competitive price and reliable quality in Korea since 1990.
