High-strength light composite cable for offshore oil drilling platform

Abstract

The invention discloses a high-strength light photoelectric composite cable for an offshore oil drilling platform, comprising a quincunx frame. Axial mounting holes are arranged in the edge and centerof the quincunx frame. Power line cores and control line cores are arranged in the mounting holes in the edge of the quincunx frame, and the power line cores and the control line cores are alternately arranged. Stainless steel tube fiber units are arranged in the mounting hole in the center of the quincunx frame, and a shielding layer is arranged at the periphery of the stainless steel tube fiberunits. A reinforcing layer, a water blocking tape and an outer protective layer are arranged in turn outside the quincunx frame. The quincunx frame is made of chloroprene rubber, which makes the overall structure of the cable stable and the process simple. With combination of the water blocking layer and the outer protective layer, the cable has excellent waterproof performance, the outer protective layer is highly resistant to wear and tear, the cable is resistant to oil, acid and alkali and seawater corrosion and can be continuously used in sea water, and the cable is light and easy to fix.

Description

technical field [0001] The invention belongs to the technical field of photoelectric cables, and in particular relates to a high-strength light composite cable for offshore oil drilling platforms. Background technique [0002] Various equipment on the offshore oil drilling platform are connected by cables to provide power, control instruments and transmit signals. Due to the particularity of offshore oil operations, the cables are often broken, the waterproof performance is not good, and the expected results of detection and research cannot be achieved. , and the weight of the cable is heavy, and it is difficult to fix and connect. Ordinary cables have a single function, do not have vertical and horizontal water blocking functions, and do not have seawater corrosion resistance, high pressure resistance, mud resistance and wear resistance, tensile resistance and drag resistance. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies in the ...
