This utility model relates to the field of cable stranding technology and provides a fire-resistant cable stranding machine, including a pressure plate. An output block is fixedly connected to the top of the pressure plate. A rotating rod is rotatably connected inside the output block. Two connecting plates are fixedly connected to the outer surface of the rotating rod. A rod sleeve is fixedly connected to the end of each connecting plate away from the rotating rod. A rotating rod is rotatably connected to the inner surface of the rod sleeve. A moving gear is fixedly connected to the end of the rotating rod near the output block. Fixed gear rings are meshed on the outer surfaces of the two moving gears. This utility model features a self-rotating and revolution-rotating stranding structure, ensuring uniform rotation of the single wire during stranding. This avoids single wire deviation or knotting due to uneven tension, controls the consistency of the stranding pitch, ensures a tight structure and uniform outer diameter of each layer of the cable, forms a stable spiral stranding structure, improves the cable's tensile and bending resistance, and prevents single wire breakage or insulation damage due to excessive twisting.

The utility model relates to a protective suspension type closing resistor unit structure, which comprises a plurality of resistor sub-strings which are arranged in a shell and are connected in series, the resistor sub-strings comprise insulating rods which are arranged on a front end cover and a rear end cover in a delta shape, a plurality of I-shaped insulating sheets which are arranged along the axial direction of the insulating rods are arranged on the insulating rods, and the insulating sheets are arranged on the front end cover and the rear end cover. An annular resistor disc is arranged in the insulation sheet, an annular deformation groove located at the corner is formed in a concave ring of the insulation sheet, and the corresponding resistor discs on different insulation rods are connected through copper sheets, space is provided for the edges of the resistor discs through the arrangement of the deformation grooves, the edges of the resistor discs are prevented from being broken, and deflection deformation of the cross-core insulation rod is reduced; through the arrangement of the outer lining, impact damage of airflow to the appearance surface structure of the resistor disc in the inflation and deflation process is prevented, and even if slight abrasion exists, dust particles fall into the trap through the arrangement of the pull-out type particle trap on the shell and the slag falling hole of the outer lining, and insulation breakdown is avoided.

This utility model relates to the field of distribution box technology. It provides a distribution box with protective functions, comprising a distribution box body, a protective component mounted on the back of the distribution box body, and an anti-collision component mounted on the side of the distribution box body. The protective component includes a mounting groove, with a protective collar threaded into the mounting groove. A sliding groove is formed on the side of the protective collar, and a sliding rod is slidably connected in the sliding groove. A mounting block is fixed to the other end of the sliding rod. This technical solution solves the technical problem in related technologies where, during use, if the sealing of the distribution box's inlet and outlet is not tight in rainy weather, rainwater can slide down the wires into the distribution box, potentially causing insulation failure or short circuits inside the distribution box.
