Abstract

The invention discloses a water-blocking composite cable for an offshore oil platform. A cable core comprises a skeleton, wherein the skeleton comprises two partially overlapping square skeletons; theskeletons of an overlapping part are primary skeletons; the skeletons of non-overlapping parts are secondary skeletons; the primary skeletons and the secondary skeletons are of an integral structure;a power line core is arranged in the primary skeletons; a control line core and a communication line core are arranged in each secondary skeleton separately; and the outer side of the cable core is sequentially coated with a cross-linked polyethylene inner sheath, a steel-tape braided armor layer and a cross-linked polyethylene outer sheath from inside to outside. The water-blocking composite cable is provided with the skeleton; the skeleton comprises two partially overlapping square skeletons; the skeletons of the overlapping part are the primary skeletons; and the skeletons of the non-overlapping parts are the secondary skeletons, so that the water-blocking composite cable plays a good protecting role in the power line core, the control line cores and the communication line cores separately, and meanwhile, the compression and tension resistance of the cable can be strengthened.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a water-blocking composite cable for offshore oil platforms. Background technique [0002] my country has a long coastline and vast sea area, rich in offshore oil resources, increasing mining projects, and increasing number of offshore oil platforms, and the supporting cables for offshore oil platforms will also usher in great development. Cables for offshore oil platforms can provide stable and reliable platforms for communication between islands and continents, between islands, homeland defense, and signal transmission in the sea. Among them, flame-retardant shielded cables for switchgear are indispensable for power supply. In the most common IEC60092-354 and NEK606 standards, the highest voltage level of power cables is 30kV. With the continuous increase of installed power, it is an inevitable trend to increase the power supply voltage, and the 30kV switch cabinet flame-retard...
