3x50+25mm² Fire Resistant Copper Cable, Steel Tape Armoured, LSZH Sheath | Alfanar

Fire resistant armoured power cable (CU/MICA/XLPE/STA/LSHF), 3.5 core stranded copper conductor. produced by Alfanar, Armored with double layers of galvanized steel tapes (STA) to give it mechanical strength to protect it from external pressures that fall on the cable. Insulated with XLPE (cross-linked polyethylene) which provides a unique combination of strength, flexibility, and reliability, making it suitable for a diverse range of applications. It can withstand high temperatures up to 90°C for extended periods without compromising performance. The cable also withstands harsh environmental conditions, including moisture, corrosion, and chemicals, making it ideal for outdoor use. Chloride-free, making it environmentally friendly. Also, it is sheathed with an outer layer of a low smoke halogen-free compound (LSHF), which minimizes smoke and toxic fumes in case of fire. Therefore, it is suitable for use in fixed installations, in applications where maintenance of power supply during a fire is required for a defined period of time, such as for essential safety circuits, fire alarm systems, and sprinkler systems, etc., in areas where smoke and acid gas evolution could pose a hazard to personnel or sensitive equipment in high-rise buildings, schools, hospitals, hotels, shopping centers, subways, etc. Available in various shapes and sizes in the highest quality and best prices to suit different applications and needs.
