The LSZH Flexible Wire RY is a Low Smoke Zero Halogen pliable copper conductor cable. The "RY" designation, commonly used in regional product codes, refers to a single-core wire with flexible polyolefin-based insulation. These cables are specifically designed for use in densely populated public venues and industrial facilities where fire safety considerations are of the utmost importance.
Key Technical Specifications
Conductor Construction
Composed of high-grade oxygen-free copper, stranded to Class 5 flexibility, specifically engineered for applications requiring sharp bend radii and frequent movement.
Insulation & Sheath Material
Manufactured using a thermoplastic polyolefin blend that contains no halogenated elements such as chlorine or fluorine.
Voltage Designation
Typically rated at either 300/500V or 450/750V, depending on the conductor's cross-sectional size.
Fire Performance Classification
Frequently identified by the WDZ code (Waterproof, Smoke-free, Zero-halogen, Flame-retardant) in product specification sheets.
Common Applications
Public Infrastructure:
Frequently mandated for use in commercial facilities including airport terminals, medical centers, and subterranean railway stations.
Industrial Automation:
Employed as internal wiring within control enclosures, equipment panels, and signal/data communication networks that demand flexible conductor interconnections.
Confined Transport Applications:
Regularly installed in marine craft, aircraft, and railway carriages where airflow is limited and space is constrained.
Benefits
Zero Acidic Gas Release:
In contrast to conventional PVC, this cable produces no hazardous halogenated fumes-such as hydrogen chloride-under combustion. This eliminates the risk of respiratory injury to building occupants and prevents corrosive damage to sensitive electronic components.
Clear Visibility During Fire:
Instead of the thick black smoke typical of standard cables, it generates only a faint, semi-translucent white haze. This ensures that escape routes and emergency signage remain visibly unobstructed in fire conditions.
Superior Bending Capability:
Thanks to its finely stranded multi-wire copper core, the cable offers excellent pliability, facilitating effortless routing through congested cable trays, control cabinets, and automated production equipment.
