Engineer’s summary: the value of this cable is dual compliance. A machine builder can wire one cabinet for both IEC and UL/CSA markets. Remember two limits: it is AWM (equipment wiring), not an NEC field-wiring tray cable, and it must not be flexed below −5 °C.

1. Reading the designation

JZ = with GNYE and numbered cores (‘G’); OZ = without GNYE (‘x’). Yö marks the oil-resistant PVC sheath (‘ö’ for Öl, oil). 1 000 V UL/CSA refers to the UL Style 2570 / CSA AWM rating; the same cable is rated 450/750 V under IEC.

2. Construction

The construction mirrors the standard JZ/OZ cable, but the sheath compound is the difference: it is formulated for increased mineral-oil resistance and for bunched-cable flame performance, and the insulation system is dimensioned for the UL 1 000 V rating and a 6 kV test.

4. Fire performance: what each test proves

Flame tests met by the cable
TestConfigurationWhat it demonstrates
IEC 60332-1Single vertical cable, 1 kW burnerSelf-extinguishing; flame does not travel along a single cable
IEC 60332-3-24 Cat. CBunched vertical cables, 1.5 l/m non-metallic volume, 20 minReduced fire propagation in cable trays and risers
CEI 20-22 IIItalian bunched-cable testAcceptance in Italian installations
NBN C30-004 Cat. F2Belgian flame-propagation categoryAcceptance in Belgian installations
CSA FT1Vertical flame test, CanadaCanadian flame rating for the AWM listing
IEC 60332-3-24 Cat. C is a propagation test, not fire resistance: the cable is not designed to keep circuits working during a fire. Where circuit integrity is required, specify a fire-resistant cable.

5. Full dimension and weight tables

All 101 constructions are listed, grouped by cross-section. Outer diameters are supplier values; bending radii are calculated from them.

Source data to verify before publication: two rows appear inconsistent in the supplied table and are shown as received — 26 G 1.5 (Cu index 619.0 = weight 619.0 kg/km; expected Cu index ≈ 374 kg/km) and 3 G 16 (weight 363.0 kg/km is below its Cu index 460.8 kg/km).

10. FAQ

Why two voltage ratings?

UL/CSA AWM Style 2570 rates the cable at 1 000 V; under IEC it is rated 450/750 V. One cable can therefore be used in a machine shipped to either market.

What does cURus mean?

UL Recognized Component marking valid for both the US and Canada, here for 80 °C and 1 000 V as appliance wiring material (AWM).

Is AWM the same as a field-wiring tray cable?

No. AWM is for wiring within equipment and machines. Field wiring in buildings under the NEC normally requires listed types such as TC-ER. Check the installation code.

What is IEC 60332-3-24 Cat. C?

A bunched-cable vertical flame test: a defined non-metallic volume of cables must not propagate flame beyond a set height. It is stricter than the single-cable IEC 60332-1 test.

Why −5 °C when moved?

The oil-resistant sheath compound is optimised for oil resistance and fire behaviour; below −5 °C, avoid flexing. Fixed installation remains possible down to −40 °C.

How many cores?

From 2 to 50 cores in 0.5–1.5 mm², up to 34 cores in 2.5 mm², and up to 7 cores to 70 mm².
