Abstract
The utility model discloses a shielding soft cable for a communication power supply. The shielding soft cable for the communication power supply comprises a round cable core which is used as a protection zero line. The outer surface of the round cable core is twisted with three first tile cable cores which are used as phase lines and a second tile cable core which is used as a zero line. The outer surfaces of the round cable core, the first tile cable cores and the second tile cable core are coated with first polyvinyl chloride layers for insulation. A polyester tape wraps the outer surfaces of the first polyvinyl chloride layers. An environment protecting glass ribbon wraps the outer surface of the polyester tape. A shielding layer coats the outer surface of the environment protecting glass ribbon. A second polyvinyl chloride layer used as an outer sheath coats the outer surface of the shielding layer, and the average thickness is 1.6mm. According to the utility model, the shielding soft cable for the communication power supply adopts a conductor of tile structure, thus the size of the outer diameter of the cable becomes small; the bonding is close; the gap is small; the use of filler is unnecessary; and the radiation performance is improved.
