Hey, I am Richard Zi, General Manager of ZW Cable and expert in cable industry for over 15 years. Cables are insulated and externally covered with polymeric materials which are organic compounds. NEC 760.176 (F) requires CI cables for NFPA fire alarm systems used to meet the survivability of critical circuits requirements and be listed for that function per NFPA 72. (PDF) Fire Retardant Coatings Fire Resistant Cables is the perfect solution to prevent fire hazards. This may be of primary concern, for instance, in life safety of fire fighting installations. But in low risk areas where the evacuation is easy and high flexibility is required, PVC could still be a good choice. Because of its low cost, it is a large number of cable varieties used in fire-resistant cables. What are the fire retardant cable coating types and advantages - Quora By this user understands the cable type. 'Standard' fire resistant cables are required to achieve at least 30 minutes circuit integrity when tested in accordance with BS EN 50200 AND also to BS EN 50200 ANNEX E. 'Enhanced' fire resistant cables are required to achieve at least 120 minutes when tested to BS EN 50200 AND also BS 8434-2. With many new advancements happening in the world every day, more and more new products are being introduced & newer technology is being developed to satisfy the innumerable requirements of people. The outdoor cables installed over-ground do not need Low Smoke Zero Halogen properties as the dense toxic smoke has space to escape. IEC 60287 Current Capacity of Cables - An Introduction. ERDA, CPRI and various other government test labs also conduct these tests for the benefit of manufacturer and buyer to certify the meeting of requirements. (1) Flame retardant PVC insulation and sheathing: fixed laying -40; non-fixed laying -15. Our fire performance cables are specifically designed to maintain circuit integrity and continue to work for a specific time under defined conditions of 30, 60, or 120 minutes. Use the Draka Sales Locator tool and monitoring via optional communication interface (WAGO USB Communication Cable and IO-Link Communication Module). It's very engaging. right? VKG: Yes, PVC has some flame retardant properties and does not propagate flame easily as PE does. In case of fire, the Fire Resistant Cables will ensure that there is little or no emission of Acid Gas & smoke (incase the cables come in contact with fire), which can cause further harm & hamper evacuation measures.
