Abstract An introduction is made to flame-retardant low-smoke non-halogen insulated cables and the radiation cross-linking process of Class IA flame-retardant low-smoke non-halogen insulated cables. Based on that，it is pointed out that high-fireproof-grade buildings such as Class 1 tall buildings and important public buildings should use low-smoke non-halogen cables with radiation cross-linked polyethylene insulated cables in accordance with JGJ 16-2008：Code for Electrical Design of Civil Buildings.

Key words　XLPE Flame-retardant low-smoke non-halogen Radiation cross-linking Flame retardant Class IA
