In recent years, there have been more and more fire accidents around the world due to power system failure, and the proportion of power supply interruption due to the fire of cable has been increasing year in, too. Therefore, in power plants and substations with a large number of electrical equipment and a large number of cable laying places often use flame-retardant cable to prevent the spread of fire, to prevent electrical problems caused by fire on the optical cable and equipment to cause significant damage.
What are the types of flame-retardant optical cables and what characteristics are there? First: Halogen-free low-smoke flame-retardant fiber optic cable, halogen-free low-smoke flame-retardant cable not only has excellent flame retardant and the use of materials without halogen components, so its combustion corrosion and toxicity is low and the amount of smoke produced very little, can effectively reduce the human body, equipment and equipment damage, and the fire occurred when the rescue was timely.
Halogen-free low-smoke flame-retardant fiber optic cable because of its high flame retardancy, corrosion resistance and low smoke concentration characteristics so that its cost-effective has been greatly improved. Second: Low halogen low smoke flame retardant cable, low halogen low smoke flame retardant fiber optic cable material contains a lower amount of halogen so that it burns with a small amount of hydrogen chloride and smoke. The fiber optic cable is characterized by its good flame retardancy and the release of hydrogen chloride during combustion and low smoke and heavy use. The basic material of low halogen and low smoke flame retardant fiber optic cable is polyvinyl chloride, which is processed by high-efficient flame retardant, hydrogen chloride absorbent and smoke inhibitor, which can remarkably improve the combustion performance of ordinary flame-retardant cable.
