Reading the designation<\/h2>\n<p>In the German cable code, <code>Y<\/code> denotes PVC and <code>C<\/code> a copper screen. Read from the inside out, <code>Y-C-Y<\/code> means PVC inner sheath, copper braid, PVC outer sheath. <code>JB<\/code> identifies versions with a green\/yellow protective conductor (shown as \u2018G\u2019 in the dimension tables) and <code>OB<\/code> versions without it (shown as \u2018x\u2019). The voltage class changes with cross-section: up to 16 mm\u00b2 the cable is rated 300\/500 V; from 25 mm\u00b2 it carries 1 kV insulation walls and is rated 0.6\/1 kV.<\/p>\n<div class=\"cards\"><div class=\"card\"><div class=\"value\">37<\/div><p>Standard sizes, from 2 \u00d7 0.5 mm\u00b2 to 4 G 185 mm\u00b2.<\/p><\/div><div class=\"card\"><div class=\"value\">\u224885 %<\/div><p>Optical coverage of the tinned copper braid.<\/p><\/div><div class=\"card\"><div class=\"value\">4 kV<\/div><p>Test voltage on every length.<\/p><\/div><div class=\"card\"><div class=\"value\">20 M\u03a9\u00b7km<\/div><p>Minimum insulation resistance.<\/p><\/div><\/div><\/section>\n\n<section id=\"construction\"><h2>2. Construction<\/h2>\n<p>The inner sheath is what separates this design from a standard CY cable. In a single-sheathed CY, the braid bears directly on the core insulation: every impact or tight bend is transferred straight through the braid wires into the PVC. In YCY, the inner sheath acts as a cushion, keeps the braid round, so its coverage stays uniform, and gives a second barrier against moisture and chemicals.<\/p>\n<div class=\"svg\"><svg

EMC: why termination beats coverage<\/h2>\n<p>A braid of about 85 % optical coverage gives a low transfer impedance across the frequency range typical of variable-speed drive switching noise. In practice, however, measured screening performance is usually limited by the termination rather than the braid itself. A twisted pigtail a few centimetres long adds enough inductance to lose most of the high-frequency benefit.<\/p>\n<div class=\"formula\">Recommended practice for VSD and signal circuits\n1. Bond the braid 360\u00b0 using EMC cable glands at the drive and at the motor terminal box.\n2. Keep the braid continuous; do not open it for more than the gland length.\n3. Separate power YCY and signal YCY on the tray, or segregate with a metal divider.\n4. For analogue signals susceptible to ground loops, earth at one end only, following the equipment manufacturer&#8217;s instructions.<\/div><\/section>\n\n<section id=\"application\"><h2>6.

FAQ<\/h2><div class=\"cards\"><div class=\"card\"><h3>Why a transparent outer sheath?<\/h3><p>The tinned braid remains visible, so crushed or opened braid areas and incorrect terminations can be spotted during inspection.<\/p><\/div><div class=\"card\"><h3>Is 85 % coverage enough for VSD motor leads?<\/h3><p>For typical industrial drives, yes, provided the braid is bonded 360\u00b0 at both ends via EMC glands. Coverage matters less than termination quality.<\/p><\/div><div class=\"card\"><h3>What do \u2018G\u2019 and \u2018x\u2019 mean?<\/h3><p>\u2018G\u2019 includes a green\/yellow protective conductor; \u2018x\u2019 (shown as \u2018;\u2019 in some source tables) has no GNYE core.<\/p><\/div><div class=\"card\"><h3>Can I use it in a drag chain?<\/h3><p>No. It is rated for free movement without tensile stress or forced guidance. Choose a chain-rated PUR\/TPE screened cable.<\/p><\/div><div class=\"card\"><h3>Why does voltage change at 25 mm\u00b2?<\/h3><p>From 25 mm\u00b2 the cable uses 1 kV insulation wall thickness and is rated 0.6\/1 kV; up to 16 mm\u00b2 it follows the 300\/500 V EN 50525-2-51 approach.<\/p><\/div><div class=\"card\"><h3>Can it be buried or used outdoors?<\/h3><p>Not buried.
