Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, the safety cable for residence of the present invention has an optical fiber unit 1 and a conductor unit 2 which are independent of each other, and 1 to 3

optical fiber units

1 and 1 to 3 conductor units 2 can be arranged inside the cable. In an embodiment of the present invention, 2

optical fiber units

1 and 2 conductor units 2 are disposed inside the cable in a staggered manner, and 2 optical fiber units 1 are disposed relatively and 2 conductor units 2 are disposed relatively. By providing the optical fibers and conductor wires in separate units and integrated into the cable, the difficulty of construction is simplified and maintenance costs are reduced. The cable is outside from inside to outside to be provided with halogen-free low smoke flame retardant polyolefin inner sheath 3, non-woven fabrics water blocking layer 4, anticorrosive polyurethane layer 5 and nylon restrictive coating 6 respectively, and halogen-free low smoke flame retardant polyolefin inner sheath 3 has good flame retardant property to smog and harmful gas when the burning are less, have protected resident's life safety when catching fire. The non-woven fabric water-blocking layer 4 has a good water-blocking function and can prevent the cable from being affected with damp and corroded.
