Embodiment Construction
[0009] An environment-friendly cable includes two cable cores, a filling layer 3, a shielding layer 4 and a sheath layer 5. The cable core includes a conductor 1 and an insulating layer 2 covering it, and the filling layer 3 is covered on Outside the cable core, the shielding layer 4 is covered outside the filling layer 3, the sheath layer 5 is covered outside the shielding layer 4, and the insulating layer 2 is a low-smoke, halogen-free, flame-retardant cross-linked polyolefin insulating layer, The filling layer 3 is a glass fiber rope filling layer, the shielding layer 4 is a braided copper wire shielding layer, and the sheath layer 5 is a low-smoke, halogen-free, flame-retardant cross-linked polyolefin sheath layer.
[0010] The conductor 1 of the present invention is composed of multiple twisted tinned copper wires.

The invention relates to an environment-friendly cable. The environment-friendly cable comprises two cable cores, a filling layer, a shielding layer and a protecting sheath layer, wherein each cable core comprises a conductor and an insulating layer arranged outside the conductor in a wrapping mode, the cable cores are wrapped in the filling layer, the filling layer is wrapped in the shielding layer, the shielding layer is wrapped in the protecting sheath layer, the insulating layers are low-smoke zero-halogen flame-retardant cross-linked polyolefin insulating layers, the filling layer is a glass fiber rope filling layer, the shielding layer is a copper braid shielding layer, and the protecting sheath layer is a low-smoke zero-halogen flame-retardant cross-linked polyolefin sheath layer. The environment-friendly cable has the advantages of being small in combustibility, free of black smoke and harmful gas and the like, the flame retardant level is effectively improved, and meanwhile the insulating performance and the flame retardant performance of the cable are guaranteed.
Description
technical field [0001] The invention relates to a cable, in particular to an environment-friendly cable and belongs to the technical field of cables. Background technique [0002] Among the existing technologies, as people's awareness of environmental protection and safety increases, people pay more and more attention to green cables. As traditional flame-retardant cables and low-smoke low-halogen flame-retardant cables, mixtures of halogen-containing polymers and halogen-containing flame retardants are widely used. Although these cables have good flame retardant properties, once a fire occurs, the cables will produce a lot of smoke and toxic corrosive gases after burning in the fire, which not only hinders fire fighting and personnel evacuation, but also corrodes instruments and equipment. Especially for closed places where many people gather, such as subways, hotels, exhibition halls and ships. Contents of the invention [0003] In view of the above defects, the object...
