[0002] High-voltage cable is a kind of power cable, which refers to the power cable used to transmit power between 1kv-1000kv, and is mostly used in power transmission and distribution. The components of high-voltage cable from inside to outside include: conductor, insulation, inner sheath, filler (armor), and outer insulation. Of course, armored high-voltage cables are mainly used for underground burial, which can resist high-intensity oppression on the ground, and prevent other external forces from damaging the power engineering cable laying specifications. When selecting wires and cables, generally pay attention to the selection of wire and cable models and specifications (conductor cross-section). ⒈ Selection of wire and cable models When selecting wires and cables, the purpose, laying conditions and safety should be considered; according to different purposes, power cables, overhead insulated cables, control cables, etc. can be selected; according to different laying conditions, general plastic insulated cables, steel belt armored cables, steel wire armored cables, anti-corrosion cables, etc. can be selected; according to safety requirements, non-flammable cables, flame-retardant cables, halogen-free flame-retardant cables, fire-resistant cables, etc. can be selected. ⒉ Selection of wire and cable specifications When determining the use specifications (conductor cross-section) of wires and cables, heating, voltage loss, economic current density, mechanical strength and other selection conditions should generally be considered.

[0003] The application number is 201920461422.7, which discloses a cable laying structure for a high-voltage power distribution cabinet, and relates to the field of cable installation technology. The cable laying structure for a high-voltage power distribution cabinet includes a mounting plate, both ends of the mounting plate are threadedly connected with hexagonal screws, both sides of the upper surface of the mounting plate are fixedly connected with damping pads, a support frame is fixedly installed in the middle of the upper surface of the mounting plate, one side of the support frame is fixedly connected with a stabilizing frame, and the other side of the support frame is movably connected with a cable buckle seat, one end of the cable buckle seat is fixedly installed with a fixing plate, both ends of the fixing plate are provided with movable grooves, and a clamping block is arranged inside the movable groove, and a screw is threadedly connected in the middle of one end of the clamping block, and a pitch-adjusting slider is fixedly connected to the upper and lower sides of the screw, and a driven gear is fixedly connected to the outer side of one end of the screw.

[0004] The above document discloses a high-voltage distribution cabinet cable laying structure with the following defects: after a certain length of the wire is laid, the tension of the inner wire loses the restraint of the outer wire, which makes the wire more and more scattered. When it is laid further, it is easy to have dead bends and twists, which seriously affects the laying of the wire. Generally, a dedicated person is required to disassemble the bundled wires and straighten them before laying them, which requires a lot of labor and affects the construction efficiency and quality.

[0005] It can be seen from this that the existing device does not have a wire laying device that can apply supporting force to the inner circle of the wire reel. It is necessary to improve the existing deficiencies and provide a high-voltage distribution cabinet cable laying structure. Utility Model Content
