Swimming power cable and preparation method thereof

Abstract

The invention provides a walking power cable and a preparation method thereof. The cable is characterized in that an insulating layer is arranged on the outer layer of each combined conductor and is formed by stranding a plurality of insulated cores; filling cores are arranged between two insulating layers and an inner sheath; a tensile layer is arranged on the outer layer of the inner sheath; and an outer sheath is arranged on the outer layer of the tensile layer. The preparation method is characterized in that tinned copper wires and special fibers are stranded by a wire and cable stranding machine to serve as inner conductors; the tinned copper wires are braided by a braiding machine to serve as outer conductors; inner insulating layers are manufactured by extruder equipment and are processed by an electron accelerator through radiation crosslinking, and outer insulating layers are manufactured by the extruder equipment; the filling cores are stranded by a cabling machine; the tensile layer is formed by a braiding machine through braiding; and the inner and outer sheathes are manufactured by the extruder equipment. The cable has the advantages of softness, low temperature and aging resistance, tear resistance, high flame retardance and high strength, has softness characteristic under low temperature, improves the tensile strength, is suitable for the special environment such as reciprocation and has excellent mechanical property and electrical property.

Description

Technical field: [0001] The invention relates to a swimming power cable and a preparation method thereof. The product can adapt to uninterrupted work in the field environment, and is suitable for use in special environments such as low temperature, high humidity, high tension, high strength, and reciprocating movement. It is suitable for cables for outdoor mobile power and electrical equipment used in special environments such as coal mines and oil fields. Background technique: [0002] At present, there is no relevant floating power cable standard in the world. In the GB / T12706.1-2008 "Rated Voltage 1kV to 35kV Extruded Insulated Power Cable and Accessories" standard, there is no relevant product in a special environment such as ① resistance to flexing; ②Cold resistance; ③Aging resistance and other performance standards. Also can't satisfy the user to the special requirements such as product low temperature, softness, high strength. Invention content: [0003] The prese...
