This high-quality LSZH (Low Smoke Zero Halogen) insulated cable complies with BS EN 50525-3-41 and is classified under BS code 2491B and hAR codes H05Z-U / H05Z-K. Rated for 300/500V, it is designed for fixed wiring in public and commercial buildings where fire safety and low smoke emissions are critical — including power stations, metro systems, airports, hotels, hospitals, petrochemical plants, and high-rise buildings. The non-sheathed structure allows for easy installation in conduits or trunking, while the LSZH insulation ensures superior flame retardancy, low toxicity, and safe evacuation conditions in case of fire.
