Abstract

The invention discloses a cable for an intrinsically safe explosion-proof ship, which comprises a conductor (1), an insulating layer (2), a packing layer (4), a wrapping band (5), a jacket (7) and the like, wherein a conducting line pair is provided with aluminum-plastic composite tape sub-shields (3), a cable core is provided with an aluminum-plastic composite tape main shield (6), and a drainage wire (8) is arranged at the insides of the aluminum-plastic composite tapes of the sub-shields and the main shield; and by adopting the sub-shields and the main shield structures, the cable for the intrinsically safe explosion-proof ship has small distribution parameter, resists external interference and line-to-line crosstalk, and the drainage wire not only is beneficial to the grounding treatment of the cable, but also can ensure the continuity of a shielding layer.

Description

technical field [0001] The invention relates to a marine cable, in particular to an intrinsically safe explosion-proof marine cable. Background technique [0002] In places with high explosion hazards such as offshore oil platforms, there are high requirements for the explosion-proof safety performance of cables transmitting automatic control signals, and ordinary marine cables cannot meet the safe use requirements of the above places. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intrinsically safe explosion-proof marine cable that can be used in places with high explosion hazards such as offshore oil platforms. [0004] In order to solve the above-mentioned technical problems, the intrinsically safe explosion-proof marine cable of the present invention is composed of a conductor, an insulating layer, a filling layer, a tape layer, and a sheath. With total shielding, the drainage line is set on the inner s...
