Description

Radiation-resistant high-low temperature resistant light-duty high-performance transmission line for marine engineering

technical field

The utility model relates to the technical field of cable manufacture.

Background technique

With the vigorous exploitation of marine resources in all countries in the world, the rapid development of marine engineering has made the demand for cables for marine engineering continue to expand, and at the same time put forward higher technical requirements for them. Offshore engineering cables refer to special cables used in offshore engineering projects, such as power, control and instrumentation cables used in various drilling rig modules, oil production platforms and other projects. Offshore oil and gas projects are full of flammable and explosive oil and gas, and offshore platform equipment needs to meet the requirements of light weight. In order to ensure the safety of electrical signal transmission in equipment, cables need to have high mechanical strength, oil resistance, mud resistance, UV protection, and Beam flame retardant, fireproof, high temperature resistance, low temperature resistance and other properties. Current conventional cables have drawbacks.

Contents of the invention

The purpose of the utility model is to provide a light-weight, radiation-resistant, high-flame-resistance, high mechanical lightness and high reliability required for marine engineering equipment and ship equipment, which is radiation-resistant, high-low temperature resistant, light-duty high-performance transmission line for marine engineering.

The utility model comprises three groups of insulated wire cores, and a braided shielding layer and a sheath layer are sequentially arranged outside the insulated wire cores; each group of insulated wire cores includes a stranded conductor, and an insulating layer is wrapped outside the stranded conductor .

The conductor (tin-plated, silver-plated, nickel-plated) of the cable of the utility model is formed by twisting multiple strands of flexible wires with the same core, and a thin-walled light insulating layer is arranged outside the conductor. The braided shielding layer of the cable is selected from high-quality tinned wire, silver-plated wire or nickel-plated wire according to the type of conductor, and braided and shielded on a high-speed braiding machine. The insulation layer and sheath layer of the cable are all made of XL-PTFE material with high temperature resistance, radiation resistance and small size.

The utility model has the following advantages: (1) The outer diameter is small and the weight is light: the conductor adopts multi-strand wires to be twisted with the same core, and the twisted structure is stable and compact, so that the outer diameter of the conductor with the same cross section is reduced a lot; the insulating layer Using XL-PTFE, the insulation thickness is ultra-thin and the specific gravity is light. (2) High and low temperature resistance: It can be used at -65°C~+200°C for a long time, and the short-term use temperature can reach above 280°C, and it can pass the 7-hour accelerated aging test at 300°C. (3) Radiation resistance: Due to the use of cross-linked materials, the cable has good fluorine stability and can resist high ionizing radiation in outer space. (4) High mechanical lightness: XL-PTFE tensile strength ≥ 34.0N/mm2; elongation at break ≥ 70% (5) High safety and reliability: The product has strong resistance to longitudinal cutting and friction, The insulating layer has excellent crack resistance.
