Abstract

The invention discloses a safe and clean type cable for a ship. The safe and clean type cable comprises four large conductors and a small conductor. Halogen-free low-smoke flame-retardant irradiation cross-linked polyolefin insulating layers are coated outside the four large conductors and the small conductor so as to form insulated cores; the insulated cores are longitudinally arranged to form a cable core; a halogen-free low-smoke flame-retardant lapped covering is coated outside the cable core; filling layers consisting of halogen-free low-smoke flame-retardant materials are arranged in gaps between the cable cores and between the cable core and the halogen-free low-smoke flame-retardant lapped covering; elastic steel bars of which two sections are C-shaped are arranged in the centers of the filling layers; the elastic steel bars are arranged back to back; a halogen-free low-smoke flame-retardant polyolefin sheath layer is arranged on the outer side of the halogen-free low-smoke flame-retardant lapped covering. The insulating layers, the lapped covering, the sheath layer and the filling layers are made of the halogen-free low-smoke flame-retardant materials, the environment is not polluted during combustion, and the mechanical property of the cable is improved due to the elastic steel bars. In addition, the cable has excellent heat aging resistance, a good bending property, high corrosion resistance and a good signal transmission performance.
