Abstract
The utility model relates to a waterproof flame-retardant halogen-free computer shielding cable. The cable comprises 12 wires. The surface of each wire is provided with an insulating layer. Every three wires are twisted to form a wire group, so that four wire groups are obtained. The outer surface of each wire group is wrapped by a wrapping tape layer. A tinned copper wire woven sub shielding layer is arranged outside each wrapping tape layer. A sub aluminium foil tape is arranged outside each tinned copper wire woven sub shielding layer. Each sub aluminium foil tape is internally provided with a tinned copper wire sub current guiding wire. The space surrounding the sub aluminium foil tapes is filled with halogen-free waterproof filling ropes. The halogen-free waterproof filling ropes are coated with a halogen-free flame-retardant wrapping tape layer. The halogen-free flame-retardant wrapping tape layer is coated with a tinned copper wire woven shielding layer. The computer shielding cable provided by the utility model does not generate poisonous black smoke (may generate a small amount of white smoke) if on fire, and has a flame-retardant oxygen index of up to 40; the cable has excellent anti-electromagnetic interference performance, and the shielding layer is prevented from oxidation caused by indoor air; besides, the cable is convenient for installation and laying.
