Low smoke halogen-free cable material can reduce the toxic and corrosive gas produced in its combustion.Low-smoke halogen-free materials are often used in poorly ventilated environments such as aircraft, train carriages or ships.Low-smoke halogen-free materials are also commonly used in the railway industry because there are high-voltage lines or signal lines transmitting the train's position under the railway.The use of low smoke halogen-free materials also reduces the accumulation of toxic gases when the circuit is damaged by fire or short circuit.

For example, in the railway industry or the shipbuilding industry, an important requirement is to protect personnel and equipment from toxic and corrosive gases. In these cases, low-smoke halogen-free materials will be required for the outer layer of cables.[1]
