Abstract
The utility model discloses a silver plated copper core composite insulation high and low temperature resistant radiation-proof light flexible wire, which comprises at least one conductor, wherein a composite insulating layer is coated outside the conductor; the composite insulating layer is wrapped by adopting a semi-directional polytetrafluoroethylene (PTFE) film to form an inner layer, the wrapping direction is toward the left, and the warping rate is over 60%; an outer layer is wrapped outside the inner layer, the wrapping direction of the outer layer is toward the right, and the warping rate is over 60%; the inner layer and the outer layer are integrated into a whole after fusing; a single-core or multi-core conductor coated by the composite insulating layer forms a cable core after twisting and bundling, and an aluminum plastic composite film is wrapped outside the cable core to form a shielding layer. The silver plated copper core composite insulation high and low temperature resistant radiation-proof light flexible wire is reasonable in structural design, and enables the wire to have the advantages of strong radiation-proof capacity, small laying space, light weight, flexibility, corrosion resistance, anti-oxidation, and convenience in installation through adopting the insulating layer to be matched with the shielding layer. The communication quality is not influenced in an environment with radiation, thereby ensuring the stability of the communication quality.
