Movable medium-voltage silicone rubber special cable resistant to high and low temperature and interference

Abstract

The invention relates to a movable medium-voltage silicone rubber special cable resistant to high and low temperature and interference. The cable comprises a plurality of flexible conductors, a semiconductive reinforcing wrapping tape, an inner shielding layer, a silicone rubber insulating layer, an outer shielding layer and a copper tape shielding layer are sequentially arranged outside each flexible conductor from inside to outside to form an insulating wire core, a PPD wrapping tape is extruded and wrapped by a plurality of insulating wire cores together to form a cable core, a woven shielding layer and a silicone rubber outer sheath are successively arranged outside the cable core from inside to outside, and a filler is arranged between each insulating wire core and the PPD wrapping tape. The movable medium-voltage silicone rubber special cable has the benefits that the cable has the characteristics of high and low temperature resistance, oil resistance, bending resistance, corrosion resistance, radiation resistance, high flexibility and the like, and can ensure the normal operation of a circuit under the conditions of laying in narrow space and at low temperature and high-intensity radiation; the service life of the cable is prolonged, and the range of application is expanded.

Description

technical field [0001] The invention relates to a special cable, in particular to a medium-voltage silicone rubber special cable for high and low temperature resistance and anti-interference movement. Background technique [0002] At present, medium-voltage cables often use the second type of compact conductor, using XLPE as the insulation layer, the minimum bending radius can only reach 15 times the outer diameter of the cable, the product is not suitable for mobile laying, and cannot meet the requirements of a smaller bending radius ;At present, the temperature resistance grades of conventional medium-voltage cables are mostly concentrated at minus 40 degrees, and the lowest laying temperature is not less than 0 degrees, which also limits the application; the electrical signals of medium-voltage cables often receive interference, and ordinary cable structures are difficult to meet strong interference conditions of use. Contents of the invention [0003] In order to solv...
