Engineer’s summary: this is the 1 kV, outdoor-capable version of JZ/OZ-YCY: 1 kV insulation walls, a 160 °C short-circuit limit and a UV-proofed black sheath, with the same inner sheath and 85 % copper braid. It can feed motors on 400/690 V drives and run outdoors, but not underground, in drag chains or under tension.

1. Reading the designation

JZ = with GNYE and numbered cores (‘G’); OZ = without GNYE (‘x’). Y-C-Y = PVC inner sheath, copper braid, PVC outer sheath. The whole range is rated 0.6/1 kV, tested at 4 kV, and sheathed in UV-proofed black PVC.

2. Construction

In a single-sheathed CY cable, the braid sits directly on the core insulation, so every impact and tight bend is transferred through the braid wires into the cores. The PVC inner sheath of YCY cushions the cores, keeps the braid round so its coverage stays uniform, and adds a second barrier against moisture and chemicals.

4. EMC: the braid only works if it is terminated

Recommended practice 1. Bond the braid 360° with EMC cable glands; avoid pigtails — a few centimetres of pigtail lose most of the high-frequency screening. 2. Keep the braid continuous up to the gland; do not open it further than necessary. 3. Segregate screened control cables from unscreened power cables on trays, or use a metal divider. 4. Bond both ends for drive and switching noise; for ground-loop-sensitive analogue signals, follow the equipment manufacturer.

10. FAQ

Which YCY to choose?

Transparent 300/500 V JZ/OZ-YCY for indoor control; this black 0.6/1 kV version for motor feeds on 400/690 V drives and outdoor runs; JB/OB-YCY when coloured cores are preferred.

Why a black sheath?

Carbon-black RAL 9005 PVC is UV-proofed, so the cable can run outdoors without extra UV protection.

Is 85 % coverage enough?

For typical industrial EMC, yes, if the braid is bonded 360° at both ends with EMC glands. Termination quality matters more than coverage.

Earth the braid at one or both ends?

Both ends for drives and high-frequency noise; for sensitive analogue signals with ground-loop problems, follow the equipment manufacturer’s instructions.

Can it go in a drag chain?

No: free movement only, without tensile stress or forced guidance.

Why 6 × d instead of 4 × d?

The braid and inner sheath add stiffness; a tighter radius would deform the braid and open gaps in its coverage.

Engineer's summary: a VFD motor lead is a high-frequency transmission line, not just a power feeder. This cable attacks the two problems that matter — capacitance (XLPE insulation) and common-mode current return (foil + braid, 360° bonded at both ends). Compared with the PE-insulated 2YSL(St)CY-J, XLPE raises the conductor limit to 90 °C, so the same cross-section carries 18–28 % more current.
