TEBAOFLEX YY / YSLY-JZ & -OZ (300/500 V) is the European-standard multi-core unshielded flexible PVC control and interconnecting cable for industrial automation, machine-tool wiring, PLC switchgear panels, conveyor lines, and HVAC control installations. Built in accordance with DIN VDE 0281 / BS EN 50525-2-11 / IEC 60227 principles using IEC 60228 Class 5 fine bare copper conductors, white-numbered black TI1 PVC cores, and a compact silver-grey RAL 7001 TM2 PVC outer jacket, it routes cleanly around tight 4 × D cabinet bends.
1. Application Scope & YY / SY / CY Control Cable Selection
OEM panel builders and plant maintenance engineers rely on YY (YSLY) wherever space-saving multi-core flexibility is required for fixed or occasionally flexed indoor control circuits:
- PLC Switchgear & Control Cabinets: High-density multi-core terminal-strip interconnects (up to
61 cores) between main enclosures, remote I/O islands, limit switches, and operator push-button stations. - CNC Machine Tools, Packaging & Conveyor Lines: Fixed cable-tray runs and vibration-tolerant flexible drops feeding relays, pneumatic valve banks, and small three-phase auxiliary motors.
- HVAC, Building Management & Process Instrumentation: Damper actuators, pump starters, and low-voltage telemetry in dry, damp, or lightly oil-misted plant rooms.

2. Cable Construction & YSLY Core Identification Codes
As seen in our factory cross-section photograph above, TEBAOFLEX YY / YSLY uses tightly concentric core stranding with zero bulky fillers for effortless gland termination:
YSLY-OZ (×): All black cores with sequential white numerals, no Green/Yellow core (standard on 2-core and isolated DC control).
YSLY-JB / -OB: Colour-coded cores per HD 308 S2 / VDE 0293-308 with (
JB) or without (OB) Green/Yellow earth.RAL 7001 (UV-stabilized Black RAL 9005 or Blue intrinsic-safety jacket available to order).3. Technical Characteristics

5. Frequently Asked Engineering Questions
Are YY control cable and YSLY control cable the same specification?
Yes. YY is the UK/BS nomenclature (PVC core insulation Y + PVC outer sheath Y), while YSLY is the continental European / VDE designation (Y PVC insulation + SL control cable + Y PVC sheath). Both describe the same 300/500 V unshielded Class 5 flexible copper multi-core industrial control cable with a grey RAL 7001 PVC outer jacket.
What do the suffixes YSLY-JZ, YSLY-OZ, YSLY-JB, and YSLY-OB mean?
In DIN VDE 0293 core coding: JZ (also denoted with G, e.g., 12G1.5) means black cores with white numbers plus one Green/Yellow protective-earth core in the outer layer; OZ (denoted with ×, e.g., 2×0.75) means black cores with white numbers and no Green/Yellow core; JB means colour-coded cores per HD 308 S2 with a Green/Yellow core; and OB means colour-coded cores without a Green/Yellow core.
How do I choose between YY (YSLY), SY, and CY control cables?
Choose YY / YSLY (this page) for general dry or damp indoor machine wiring, control cabinets, and conduit trays free from heavy mechanical impact or high electromagnetic interference (EMI). Choose SY (galvanized steel wire braid) where swarf, crushing, or foot traffic requires mechanical armour, and choose 2YSLCY / CY copper-screened cable where PLC analog signals or VFD motor leads require 360-degree EMC shielding.
Can YY / YSLY control cable be used in continuous drag chains or outdoors?
Standard YY / YSLY is designed for fixed installation (4 × D bend radius, -40°C to +80°C) and occasional free, non-recurring flexing without tensile load (15 × D bend radius, -5°C to +70°C), not continuous high-cycle drag chains or unprotected direct sunlight. For outdoor UV exposure specify our black UV-stabilized PVC sheath option, and for continuous drag chains request Class 6 PUR-sheathed motion cables.
What voltage and flame-retardant standards does TEBAOFLEX YY / YSLY meet?
Standard YY / YSLY control cables are rated 300/500 V (with 0.6/1 kV heavy-wall YSLY-JZ 1kV power/control variants available on request), factory dielectric-tested up to 4,000 V AC, and self-extinguishing in accordance with IEC 60332-1-2 / EN 60332-1-2.
What details are required for a YY / YSLY control cable factory quotation?
Provide your required core count and conductor size (e.g., 2×0.75 mm² OZ, 7G1.5 mm² JZ, 18G1.0 mm² JZ, or 5G6 mm² JZ), core identification code (JZ, OZ, JB, or OB), outer jacket colour (standard RAL 7001 grey or UV black), and drum or reel lengths.
