APPLICATION
This product is an unarmored, low-smoke zero-halogen (LSZH) sheathed cable, specifically designed for installation in indoor and damp environments. It is widely used in industrial manufacturing plants, workshops, and similar settings, providing reliable connectivity for communication, data, and voice transmission signals and services, as well as for interconnections between electrical equipment and instrumentation.
The core advantage of the product lies in its exceptional fire safety performance. The LSZH sheath significantly reduces the emission of toxic smoke and corrosive gases under fire conditions, ensuring personnel evacuation safety and the continuous operation of critical equipment. The cable design complies with international standards such as BS EN 50288-7 and has passed a series of rigorous fire tests, including certifications for circuit integrity (IEC 60331-21), flame retardance (IEC 60332), low flame spread, halogen-free, low corrosive gas emission, and low smoke density (IEC 61034). Higher-grade fire resistance ratings such as BS 6387 CWZ and BS EN 50200 are also available as options.
The cable structure is robust and durable. The conductors are made of copper wires compliant with IEC 60228, while the insulation layer is cross-linked polyethylene (XLPE), with optional materials including LSZH, PE, or PP. The pairs are uniformly twisted, and optional individual shielding and/or overall shielding with aluminum-plastic composite tape are available to effectively resist electromagnetic interference. The outer sheath is made of standard-compliant LSZH material, and special properties such as UV resistance, oil resistance, hydrocarbon resistance, and rodent/termite resistance can be provided upon request.
Its electrical performance is stable, with a rated voltage of 300/500V, a wide operating temperature range (-30°C to +90°C), and a minimum bending radius of only 7.5 times the cable's outer diameter, facilitating on-site installation and laying.
