Abstract
The invention discloses a halogen-free low-smoke flame-retardant control cable which comprises a plurality of conductors, wherein halogen-free low-smoke flame-retardant polyolefin insulating layers are wrapped at the peripheries of the plurality of conductors; sheath layers are wrapped at the peripheries of the halogen-free low-smoke flame-retardant polyolefin insulating layers; and the halogen-free low-smoke flame-retardant polyolefin insulating layers are composed of the following components by weight percent: 15-45% of ethylene-fatty acid vinyl copolymer, 5-15% of nitrile rubber, 30-50% of a fire retardant, 0.8-2% of an antioxidant, and 2-5% of a crosslinking sensitizing agent. By improving the insulating layers of the control cable, the flame-retardant property of the control cable is improved, and the halogen-free low-smoke inflaming of the control cable is realized.
