Low smoke halogen-free cable material granulator
Production line
Low-smoke halogen-free flame retardant cable products are suitable for transmitting electric energy in power lines with rated voltage of ./ and below. Description of product implementation standards enterprise standard low-smoke halogen-free cables
Low-smoke halogen-free cables can be divided into low-smoke halogen-free flame-retardant series and low-smoke halogen-free fire-resistant series. Low-smoke halogen-free cables are produced by our company in French standards and series standards, national standards/and international standards.
Low-smoke halogen-free flame-retardant cable is difficult to catch fire and has the ability to prevent or spread. Moreover, once it catches fire, it has the characteristics of halogen-free, low-smoke, non-toxic, and non-corrosive. Applicable to high-rise buildings, hotels, hospitals, subways, nuclear power plants, tunnels, power plants, mines, petroleum, chemical industry, etc. In addition to meeting the characteristics of low-smoke halogen-free flame-retardant cables, low-smoke halogen-free fire-resistant cables can also meet the line power supply capability under fire conditions. Mainly used in fire alarms, fire fighting equipment, smoke exhaust equipment, as well as emergency passage transportation, lighting and other emergency facilities power supply lines in places where fire resistance is required. The flame retardant grade of low smoke halogen-free cables is divided into four levels according to the specified test conditions. Flame retardant grade Fire supply temperature Fire supply time Volume carbonation height of non-metallic materials for laying cables in bundles Self-rest time ℃ l/m.m ℃.l/m.m ℃.l/m.m ℃.l/m.m
The insulation of low-smoke halogen-free cables is made of halogen-free cross-linked polyethylene, and the sheath is made of halogen-free polyolefin
materials, so all materials making up the cable do not contain halogens. The amount of smoke released when the cable is burned is very small, it does not produce very thick acid mist, poisonous gas, and has very little toxicity.
