Description
Technical Field
The present invention relates to the field of cables.
Background
In recent years, with the increasing development of marine resources in China, particularly the great attention on the exploitation of marine oil, a comprehensive offshore platform is developed rapidly, a high-performance monitoring device is injected into the platform continuously, an advanced camera is needed to acquire various video information, the normal operation state of the whole monitoring system is guaranteed, all facilities of the platform are ensured to be in a safe operation mode all the time, wherein a cable for connecting the camera is one of the most important components, and a core link of information transmission is played. The existing cable has the defects of unstable operation of a monitoring system, more matched circuits, inconvenience for field use and easiness in disorder due to unreasonable structure.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide the special cable for the camera of the monitoring system of the offshore oil platform, which meets the requirements of field work.
The purpose of the utility model is realized as follows: the special cable for the camera of the offshore oil platform monitoring system comprises a cable core, a high flame-retardant PE tape isolation layer, a low-smoke halogen-free flame-retardant irradiation cross-linked polyolefin inner protection layer, a galvanized steel wire woven armor layer and a low-smoke halogen-free flame-retardant irradiation cross-linked polyolefin outer sheath which are sequentially arranged from inside to outside; the cable core is formed by CAT5E super five types of shielding net twine and the concentric transposition of a power core, and the power core includes three group tin-plated copper conductor, all sets up the insulating layer outside every group tin-plated copper conductor, has the total shielding layer of plastic-aluminum composite tape around the package after three group tin-plated copper conductor transposition that are equipped with the insulating layer.
The utility model has the beneficial effects that: CAT5E super five-class shielding network cable has good shielding performance, high temperature resistance, strong fireproof effect and longer service life, can effectively ensure the transmission quality of network signals and reduce the network maintenance cost. The main shielding layer of the insulating layer aluminum-plastic composite belt of the power wire core can avoid interference, the inner sheath is used for sealing and protecting the cable core, the outer sheath can protect the inner sheath, and the cable has certain mechanical strength so that the cable is not damaged and corroded by external force.
Therefore, the utility model has the advantages of compact and compact structure, small volume, flame retardance, interference resistance, collision resistance, moisture resistance, salt mist corrosion resistance, sunlight ultraviolet radiation resistance, weather resistance, stronger digital transmission, accuracy, stability, reliability and the like. The long-term allowable working temperature of the cable conductor is not more than 90 ℃, the use environment temperature is minus 20 ℃ to minus 80 ℃, and the installation and laying temperature is not lower than minus 15 ℃. The cross section of the three groups of tin-plated copper conductors provided with the insulating layers is within the range of 0.5-2.5 square millimeters. The utility model is suitable for a modern offshore oil platform monitoring system and is used as a special line for connecting a camera.
In order to ensure the roundness, the cable core also comprises a low-smoke halogen-free flame-retardant tearing tape filling layer, and the low-smoke halogen-free flame-retardant tearing tape filling layer, the CAT5E super-five shielding mesh wire and the power line core are twisted.
The insulating layer of the utility model is a crosslinked polyethylene insulating layer.
