It is measured as per IS 10810 Part 64 or ASTM D 2863. The insulation layer uses flame retardant. find a supplier near to you or your site. Disadvantages [ edit] The termination points: While the length of the MI cable is very tough, at some point, each run of cabling terminates at a splice or within electrical equipment. Some ingredients are now available which if mixed with PE it can reduce its inflammability. Costs still have precedence over safety. For these applications, Fire Survival cables which can operate for a definite duration under direct fire without disrupting the integrity of the circuit, are recommended. Generally, for outdoor application where the cables are buried, Low Smoke Zero Halogen properties are not needed as the oxygen level is low and does not support burning. Halogen-free cable flame retardant principle is to rely on the precipitation of water to reduce the temperature to extinguish the fire roast. For example, if the oxygen index of a material is 21 percent, it means that the material will burn by itself even at room temperature because at room temperature the normal oxygen content is 21 percent.
