Mud-resistant cable for oil platform

Abstract

The invention belongs to the technical field of cables, particularly relates to a mud-resistant cable for an oil platform, and aims to solve the problems that a cable cannot be fixed in mud, solid substances in the mud can be in contact with the outer wall of the cable to collide in the shaking process, and optical fibers in the cable can be repeatedly deformed after frequent collision, so that internal wear is easily caused. Comprising a buffering cavity bottom layer, a buffering cavity top layer is arranged outside the buffering cavity bottom layer, a plurality of pressing seats are arranged on the inner wall of the buffering cavity bottom layer, the pressing seats are distributed at equal intervals in the circumferential direction, and symmetrical rectangular grooves are formed in the pressing seats. The buffer cavity is additionally arranged in the designed cable, the cable is suitable for being used in the slurry environment in the oil exploitation process, pressure applied to the outside of the cable can be buffered and offset through the overturning plate and the reset spring distributed in the buffer cavity, and the situation that the pressure is transmitted to optical fibers in the cable, and the optical fibers are damaged under continuous impact is avoided; and the slurry resistance of the cable is improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a mud-resistant cable for an oil platform. Background technique [0002] A rope-like cable made of several or groups of conductors (at least two in each group) twisted together, each group of conductors is insulated from each other and usually twisted around a center, and the entire outside is covered with a highly insulating covering layer, the cable has the characteristics of internal electrification and external insulation. [0003] Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mine cables, aluminum alloy cables, etc.; Composed of multi-strand wires and insulating layers, they are used to connect circuits, electrical appliances, etc. Cables can be divided into DC cables and AC cables according to the photovoltaic power station syst...

AI Technical Summary

Problems solved by technology

[0004] In the process of oil exploitation, due to the special environment, the cable will be used in the mud. Since the cable cannot be fixed in the mud, the solid matter in the mud will contact the outer wall of the cable and collide during the shaking process. When the collision is frequent , the optical fiber inside the cable is repeatedly deformed, making it prone to internal wear
