SY PVC (YSLYSY) Cable
The SY PVC (YSLYSY) Control Cable is a robust, steel wire braided 300/500V flexible multi-core connection cable engineered specifically for tooling machinery production lines, instrumentation, and control equipment in dynamic applications requiring free movement without tensile load.
What is SY PVC (YSLYSY) Cable?
The SY PVC (YSLYSY) cable is a low-voltage, galvanized steel wire braided flexible multi-core control cable featuring Class 5 flexible stranded copper conductors, PVC insulation, a PVC inner sheath, a GSWB mechanical armour, and a transparent 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 connection up to 300/500V in tooling machinery, automated assembly lines, and industrial measuring circuits without tensile load.
Engineered for harsh indoor production environments requiring mechanical reinforcement, the cable incorporates a robust layer of galvanized steel wire braid over the inner bedding. This GSWB armour effectively withstands transverse mechanical stresses, cuts, and crushing hazards on active factory floors while simultaneously acting as a magnetic shield against electromagnetic interference, all sealed beneath a transparent outer jacket that facilitates rapid visual inspection of the underlying braid.
SY PVC (YSLYSY) Cable Construction
- Conductor: Class 5 flexible stranded plain bare copper conductors per IEC/EN 60228 delivering exceptional conductivity and dynamic flex fatigue resistance.
- Insulation: High-grade Polyvinyl Chloride (PVC) compound engineered for dependable dielectric strength up to +80°C.
- Bedding / Inner Sheath: Polyvinyl Chloride (PVC) compound extruded over the assembled cores to provide a uniform bed for armouring.
- Screen / Armour: Galvanized Steel Wire Braid (GSWB) serving as heavy-duty mechanical protection against transverse loads and magnetic interference.
- 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: Transparent.
Applications
SY PVC (YSLYSY) cables are specifically designed for instrumentation, regulation, and power links across automated manufacturing lines and processing equipment where mechanical impact protection and magnetic screening are essential. Their oil- and moisture-resistant design makes them suitable for free-movement flexible use in dry, moist, and wet indoor industrial rooms.
Typical installation environments include:
- Tooling Machinery & Production Lines: Connecting CNC equipment, stamping presses, and automotive assembly cells subject to physical impact.
- Conveyors & Material Handling Systems: Flexible cabling for sorting tracks and packaging lines exposed to transverse mechanical forces.
- Industrial Control Panels & Automation Units: Power and control links routed through multi-axis machinery requiring magnetic interference attenuation.
- Indoor Wet & Moist Processing Facilities: Flexible machinery interconnects in manufacturing halls, excluding outdoor and direct underground installations.
Specifications & Dimensions
The SY PVC (YSLYSY) cable portfolio encompasses multi-core configurations from 2 cores up to 25 cores (with 4-core designs extending up to 95mm²), across conductor cross-sections from 0.75mm² to 95mm² supporting continuous current loading up to 223A 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 moved applications from -5°C to +70°C, maintaining a minimum bending radius of 4× OD (fixed) and 12.5× OD (flexed). Conductor DC resistance values span from 26 Ω/km (0.75mm²) down to 0.206 Ω/km (95mm²), with all insulation thicknesses, inner bedding layers, GSWB braid densities, and transparent outer sheaths strictly aligned with VDE 0207-363-3 and European harmonized standards.

Frequently Asked Questions
Q: What is the technical advantage of the transparent PVC outer sheath on SY (YSLYSY) cables?
A: The transparent outer jacket allows maintenance personnel to visually inspect the condition and continuity of the galvanized steel wire braid (GSWB) for mechanical damage, wear, or internal contamination without stripping the cable.
Q: Can the SY PVC (YSLYSY) control cable be installed outdoors or directly underground?
A: No, SY PVC cables are engineered specifically for indoor dry, moist, and wet room environments; they are not rated for outdoor UV-exposed installation or direct underground burial without specialized external conduit.
Q: What are the minimum bending radius limits for SY 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 industrial export orders?
A: We provide standard international commercial payment terms including Telegraphic Transfer (T/T) and 100% Irrevocable Letter of Credit (L/C) at sight for engineering contractors, plant fabricators, and automation integrators.
