When the cables are exposed to fire, these polymeric materials start decomposing releasing halogen and dense toxic smoke causing asphyxiation and impairing visibility. PVC can be made resistant to a wide range of chemicals including oils, acids and alkalis, and is tough, durable and resistant to abrasion. Indian Standard has also amended the cable specification with introduction of FR/ FRLS type cable as new varieties considering fire safety. Outer jacket of the cables are of flame retardant material only, which doesnt allow fire propagation. Although flame-retardant cables have many advantages that are more suitable for chemical enterprises, such as low halogen, low-smoke flame-retardant . By this user understands the cable type. There are enormous differences between flame-retardant cables and fire-resistive cables. Circuit integrity cable is needed when circuit integrity is essential for life safety or when it is critical to prevent a plant shut down. Therefore, from the angle oftheoretically, a fire-resistant layer can be added to the structure of the flame-retardant cable to form a flame-retardant wire orcable and fire-resistant cable. These CI cable constructions are as flexible as standard fire alarm cables, making them as easy to install as cables that are not fire-rated. However, flame retardant cables have many advantages that are more applicable to chemical companies, such as low halogen, low smoke flame retardant, etc. The higher the oxygen index, the more retardant the cable will be. We are offering cables with fire retardant compounds which reduce fire propagation and there are fire retardant low smoke compounds which besides reducing fire propagation produces low smoke. Recently I have seen a few interesting articles on viable cold fusion; the combining of atoms at room like temperatures to create boundless energy.

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. Amitava Bose: The genre of fire safe cables includes a wide variety. As far as insulation is concerned, PE or XLPE (cross-linked polyethylene) has got more advantage over PVC. Burning time 90min (recommended) Burning time 90min (recommended) Insulation. However many people including lots of buyers we met withcan not distinguish the flame retardant cable, fire resistant cable and fire preventive cable. By Steven McFadyen on July 4th, 2013 Fire resistant and fire retardant cable sheaths are design to resist combustion and limit the propagation of flames. 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. Save my name, email, and website in this browser for the next time I comment. It is measured as per IS 10810 Part 63 or ASTM D 2843. This is even before British Standards for fire resistance became available. if source of fire (heat) is more than at 21 percent also cable can act as fuel. Low smokes cables have a sheath designed to limit the amount of smoke and toxic halogen gases given off during fire situations. Benefits Of A Control Cable In A Plethora Of Settings. Fire resistance class A (Class IA~Class IVA) Class I~IV. Because the refractory layer of the fire-resistant cable can usually be wrapped directly on the wire using different fire-resistant materials. (3) Low-halogen, low-smoke flame-retardant PVC insulation, and sheathing: 70; Halogen-free, low-smoke flame-retardant polyolefin insulation and sheathing: 90 and 125 both. 1.The insulating layer is made of flame retardant materials. (1) Flame retardant PVC insulation and sheathing: fixed laying -40; non-fixed laying -15. Because of the fire-resistant layer of fire-resistant cables, multi-layer mica tapes are usually used to wrap the wires directly. Due to relative low cost, fire retardant cables are widely used as fire survival cables. Also, mineral insulated cable is a better performance of fire-resistant cables made of copper core, copper sheath, magnesium oxide insulation material processing, referred to as MI (mineral insulated cables) cable.
