▎ 摘　　要

NOVELTY - Cable comprises a wire core (1) provided with a conductor (11), a filling layer (13) and a wrapping belt (14). Multiple filling ropes (2) are set between four wire cores. An outer sheath (4) is extruded on an outer wall of a shielding layer (3). An insulating layer (12) is a double-layer extruded composite structure. An inner layer is provided with a high-density polyethylene insulating layer. An outer layer is provided with a ceramic forming silicone rubber insulation layer. A wrapping shielding layer (31) is overlapped on an outer wall of a cable core. A woven shielding layer (32) is covered on an outer wall of the wrapping shielding layer to form a double-layer shielding layer. A drainage wire (33) is arranged between the wrapping shielding layer and the woven shielding layer. The wrapping shielding layer is made of a polyester fiber film as a base material. USE - Light fire-resistant flexible data transmission shielding cable for ship. ADVANTAGE - The cable realizes digital signal transmission and fire-resistant performance at the same time without changing the size of the insulating structure. The flexible stranded structure conductor is matched with the double-layer composite insulation to make the cable finished product bending radius is 4 times of the cable outer diameter, far less than YD/T1019 specified minimum 10 times cable out diameter requirement. The graphene shielding tape overlaps and tinned copper wire woven double layer shielding avoids the data transmission cable is affected by strong electricity when the ship narrow space application, effectively reducing the damage to the cable. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation method of light fire-resistant flexible data transmission shielding cable for ship. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the light fire-resistant flexible data transmission shielding cable for ship. 1Wire core 2Filling rope 3Shielding layer 4Outer sheath 11Conductor 12Insulating layer 13Filling layer 14Wrapping belt 31Wrapping shielding layer 32Woven shielding layer 33Drainage wire
