LIHH cables are used in the industrial applications for indoor use for signal transmission. These can be easily used with their flexible construction in narrow applications like electronic control systems of computer or audio systems or the communication sector, electronic circuits, measurement devices, machine design, office equipment, etc.LIHH cables have HFFR material in their construction and These don't burn easily and the flames go off by themselves. These have low smoke density and these don't emit poisonous and corrosive gases during the fire. These used in buildings where there are important goods or human population.
