Company History

VDA 6.3 certified for Automotive Solution.

Large size coaxial litz cables to melt down metals were developed for the quick and competitive induction heating.

In addition, we made induction heating cables with Glass Tape + Kevlar(N-66) to withstand 300°C ambient temperature.

100mm OD cable(8,000㎟ square) was developed for VLF(Very Low Frequency) radar equipment.

We succeeded to extrude Teflon(ETFE, RED) less than 0.255mm thickness on litz wire.

We supplied the cable(0.1mm x 9,900 strands with XLPE+PVC) to Korea Railroad Research Institute for wireless power of KTX HEMU(more than 400km speed). The trial test was succeeded.

Development : Litz Cable(700A), 0.12mm x 16,500 strands with XLPE extrusion + non-woven binder tape + PET film for wireless power of current supplying system of electric buses on very high frequency in Gumi, Korea.

Development : 0.060mm x 9,000 strands with teflon extrusion (round type, 1.4mm thickness, jacket color: Black or custom-made) for high frequency wireless power (current supplying system) on 23KHZ.

0.08mm x 2,500 stranded with teflon extrusion (round type, 1mm thickness for preventing pin hole, jacket color: RED or custom-made) for high frequency wireless power (current collecting system) on 20kHz.

German 'B' company suggested us to develop the cable using for electric trains and we supplied high capacity cable with Kapton lapping.

Our R&D dept. made '52strands x 0.04mm(a conductor, silver plated copper wire) with PFA(=Perfluoralkoxy) teflon extrusion' for an air equipment. The Litz cable of 16~17 square meter was developed for On-line Electric Vehicle(Wireless Power Charging System)

YDK Group developed Self-bonding Litz Wire for non-contact, contactless or wireless power system for USA partner. The application: cell phone charger, non-contact charger for various transportation, home application etc. And our product range has been enhanced as following. - 0.030mm x 1150, 2150, 3150 strands with teflon sleeving / 0.10mm x 16,500 strands with double Kapton wrapping

Our R&D dept. developed 3PLY Kapton covered as following on 29th Dec. 2011. - Kapton overwrapping 30-35% - Rectangular ( tolerance ) 0.070/1,000 strands : 3.2 x 2.7mm + - 0.2 - Rectangular ( tolerance ) 0.080/160 strands : 1.6 x 1.2mm + - 0.2 - 3PLY Kapton wrapping has an excellent corona discharge compared to 2PLY.
