YY Cable

What is YY PVC (YSLY) Cable?

The YY PVC (YSLY) cable is a low-voltage, unarmored and unscreened flexible multi-core control cable featuring Class 5 flexible plain copper conductors, PVC insulation, and a grey PVC outer sheath complying with VDE 0207-363-3, VDE 0482-332-1-2, and IEC/EN 60332-1-2 standards. It is designed for fixed wiring and free-moving flexible signal, instrumentation, and power distribution up to 300/500V in tooling machinery production lines, industrial process control, and measuring equipment without tensile load.

Engineered for lightweight and compact interconnection within indoor factory environments, the cable utilizes high-purity fine-stranded copper cores paired with smooth, high-grade PVC extrusion. This unshielded geometry facilitates effortless handling, tight bend routing, and clean sheath stripping, providing dependable mechanical flexibility in dry, ambient, and wet plant facilities while resisting thermal stress and mechanical wear.

YY PVC (YSLY) Cable Construction

• Conductor: Class 5 flexible stranded plain bare copper conductors per IEC/EN 60228 delivering superior conductivity and physical flexibility.
• Insulation: Polyvinyl Chloride (PVC) compound engineered for stable dielectric performance up to +80°C.
• Bedding / Inner Layer: Compact multi-core bunching assembly optimized for smooth routing and flexible handling.
• Screen / Armour: Unscreened / Non-armored design engineered for minimum overall diameter and lightweight installation.
• Outer Sheath: Specially formulated industrial-grade Polyvinyl Chloride (PVC) compound type TM54, flame retardant per IEC/EN 60332-1-2.
• Core Identification: 2 cores: Black with White numbers; 3 cores and above: Black with White numbers + Green/Yellow protective earth conductor (colour-coded cores available upon request).
• Sheath Colour: Grey.

Applications

YY PVC (YSLY) cables are specifically designed for interconnection of control panels, tooling machinery, and automated assembly equipment across industrial processing facilities where unshielded, flexible wiring is required. Their durable PVC construction ensures long-term operational reliability in indoor dry, ambient, and wet environments under free movement without tensile stress.

Typical installation environments include:

• Tooling Machinery & Production Lines: Interconnecting CNC equipment, packaging conveyors, and automated assembly stations.
• Control Panels & Switchgear Enclosures: High-density internal cabinet wiring, relay modules, and distribution racks demanding small bending radii.
• Industrial Instrumentation & Process Control: Connecting sensors, measurement instruments, and Programmable Logic Controllers (PLCs) in factory halls.
• Indoor Wet & Dry Environments: Flexible machinery links in manufacturing rooms, excluding external and direct underground installations.

Specifications & Dimensions

The YY PVC (YSLY) cable portfolio encompasses multi-core configurations from 2 cores up to 61 cores, with nominal conductor cross-sections spanning 0.5mm² to 35mm² (supporting continuous current carrying capacities up to 135A at 30°C). Operating at a rated voltage of 300/500V, the cable supports fixed ambient temperatures from -40°C to +80°C and flexed installation from -5°C to +70°C, maintaining a tight minimum bending radius of 4× OD (fixed) and 12.5× OD (flexed). Conductor DC resistance values range from 39 Ω/km (0.5mm²) down to 0.554 Ω/km (35mm²), with all insulation thicknesses, outer sheath dimensions, and cable weights strictly aligned with VDE 0207-363-3 and European harmonized standards.

Frequently Asked Questions

Q: What is the primary difference between YY (YSLY), CY (YSLYCY), and SY (YSLYSY) control cables?
A: YY is an unshielded flexible control cable for standard indoor machinery; CY incorporates a tinned copper braid screen (TCWB) for electromagnetic compatibility (EMC); and SY features a galvanized steel wire braid (GSWB) armor for enhanced mechanical impact protection.

Q: Can the YY PVC (YSLY) control cable be installed outdoors or directly underground?
A: No, YY cables are specifically engineered for indoor dry, ambient, and wet room applications; they are not rated for external UV-exposed runs or direct underground burial without specialized protective conduit.

Q: What are the minimum bending radius limits for YY PVC control cable?
A: The cable requires a minimum bending radius of 4 times the overall diameter (4× OD) for fixed installations and 12.5 times the overall diameter (12.5× OD) for flexible, moved applications without tensile load.

Q: What payment terms does Huadong Cable accept for international export contracts?
A: We provide standard international commercial terms including Telegraphic Transfer (T/T) and 100% Irrevocable Letter of Credit (L/C) at sight for engineering contractors and industrial machinery OEMs.
