Abstract

The invention relates to a water-resisting, inflaming-retarding and halogen-free computer shield cable. The water-resisting, inflaming-retarding and halogen-free computer shield cable includes twelve wires. The surface of each wire is provided with an insulating layer. Every three wires form a wire set in a pair twisting mode, so that four wire sets are formed totally. The outer surface of each wire set is wound with a belting layer. The outer portion of each belting layer is provided with a tinned copper wire braiding branch shield layer. The outer portion of each tinned copper wire braiding branch shield layer is provided with a branch aluminum foil belt. Each branch aluminum foil belt is internally provided with a tinned copper wire branch guide line. The periphery of the outer side of each branch aluminum foil belt is filled with a halogen-free and water-resisting filler rope. Each halogen-free and water-resisting filler rope is wrapped with a halogen-free and inflaming-retarding belting layer. Each halogen-free and inflaming-retarding belting layer is wrapped with a tinned copper wire braiding shield layer. When the water-resisting, inflaming-retarding and halogen-free computer shield cable burns, poisonous black smoke is not generated, a little amount of white smog will be generated, and the inflaming-retarding oxygen index reaches 40. The water-resisting, inflaming-retarding and halogen-free computer shield cable has the advantages that the anti-electromagnetic interference is excellent, the shield layers have the remarkable effect of preventing outdoor air from being oxidized, and installing and laying are convenient.
