Abstract

The utility model relates to an environment-friendly flame-retardant computer shield cable. The cable comprises wires. The outer surface of each wire is coated with a thermoplastic halogen-free flame-retardant polyolefin insulating layer. Each thermoplastic halogen-free flame-retardant polyolefin insulating layer is wrapped by a wrapping tape insulating layer. Each wrapping tape insulating layer is coated with a flexible copper-aluminum composite tap wrapping sub shield layer. The halogen-free flame-retardant filling ropes are wound around the flexible copper-aluminum composite tap wrapping sub shield layers and fill the space outside the copper-aluminum composite tap wrapping sub shield layers. The halogen-free flame-retardant filling ropes are wrapped by a flexible copper-aluminum composite tap wrapping shield layer. The flexible copper-aluminum composite tap wrapping shield layer is coated with an oxygen-free copper wire woven shield layer. The oxygen-free copper wire woven shield layer is coated with a halogen-free flame-retardant tape wrapping insulating layer. A sheath is formed on the outside of the halogen-free flame-retardant tape wrapping insulating layer through extrusion. The environment-friendly flame-retardant computer shield cable provided by the utility model has the advantages of reasonable structure design, low cost and excellent shield performance. The insulating layer and the sheath of the cable are made of thermoplastic halogen-free flame-retardant polyolefin, so that the cable has good flame-retardant properties and physical and mechanical properties.
