Description

Technical Field

[0001] The utility model relates to the technical field of overhead conductors, in particular to a combined overhead insulated conductor. Background Art

[0002] Overhead lines, as opposed to cables, are lines that transmit electrical energy by erecting conductors at a certain height on towers. A composite conductor is a winding wire with a fully enclosed insulation layer formed by combining at least two single-clad copper flat wires and then continuously wrapping them with multiple layers of electrical insulation paper. For example, prior art publication number CN204792042U proposes a paper-insulated composite conductor structure comprising multiple conductor bodies, each of which is individually wrapped with a first insulating paper. The conductor bodies wrapped with the first insulating paper are then stacked and connected, and the stacked and connected conductor bodies are then fully enclosed with a second insulating paper to form an integrated composite conductor structure. The structure is characterized in that the connection sides of the conductor bodies wrapped with the first insulating paper are each provided with a self-adhesive layer, and a backing paper is provided between the self-adhesive layers. However, overhead conductors are generally installed in fields and transmit long distances. In rainy and snowy weather, snow easily accumulates on the conductors, burdening them. Furthermore, when the snow melts or it rains, water easily flows down the conductors and penetrates into the conductor connections, posing a potential risk. Utility Model Content

DETAILED DESCRIPTION

[0018] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0019] like Figures 1 to 6 As shown, an insulating layer 2 is cast on the outside of the conductor core 1, and an insulating filler 4 is cast on the outer surface close to the insulating layer 2 to connect multiple conductor cores 1 into one. A sheath layer 3 is installed at the position where the insulating layer 2 contacts the insulating filler 4. An inner metal sheath 8 is installed on the side of the sheath layer 3 that contacts the insulating layer 2. An insulating fiber mesh layer 6 is installed at the position where the insulating filler 4 contacts the cable rubber sheath 5. A metal sheath layer 7 is installed on the inner wall of the insulating fiber mesh layer 6 close to the insulating filler 4. The outer surface of the insulating filler 4 is provided with a metal outer skin layer 7. The cable rubber sheath 5 is provided with a convex ring 9 installed on the outer wall of the cable rubber sheath 5. A groove 10 is provided between two adjacent convex rings 9. The convex ring 9 and the groove 10 are both arranged in an arc shape. The clamping ring 11 is clamped on the outer wall of the cable rubber sheath 5. Fixed plates 12 are installed at both ends of the clamping ring 11. A connecting cap 13 is buckled and mounted above the two fixed plates 12. A screw 14 is screwed on the left side wall of the connecting cap 13. A nut is provided at the left end of the screw 14. A splint 15 is movably connected to the right end of the screw 14.

[0020] When laying the conductor, place the clamp ring 11 in a fixed position, buckle the connecting cap 13 between the two fixing plates 12, turn the bolt, and push the clamping plate 15 through the screw 14 to make the two fixing plates 12 close to each other, so that the clamp ring 11 is installed on the conductor, increasing the contact area between the conductor and the overhead insulator, preventing the conductor from sliding on the insulator, and ensuring stability after laying. In rainy and snowy weather, snow falls on the upper surface of the convex ring 9, and the arc-shaped convex ring 9 can make the snow slide easily, reducing the amount of snow falling on the conductor and reducing the burden on the conductor. When the snow melts and it rains, water flows in the groove 10, preventing water from flowing on the surface of the cable rubber sheath 5. After the water flows to the bottom of the groove 10, it drips directly downwards, improving safety. The convex ring 9 and the groove 10 are set to be arc-shaped, which will not affect the installation and pulling. The electric energy is transmitted through the conductor core 1. The insulating layer 2 and the insulating filling 4 have insulating properties, and the multiple conductor cores 1 are insulated. The internal conductor core 1 can be protected by the sheath layer 3 to avoid scratching the external cable rubber sheath 5 and the insulating filling 4 on the internal conductor core 1 during laying. The inner metal sheath 8 can effectively prevent static electricity accumulation and protect the conductor core 1 from static electricity interference and damage. The metal outer skin layer 7 can improve the overall anti-static effect, prevent static electricity accumulation, protect the cable from static electricity interference and damage, and provide additional mechanical protection to prevent the cable from external mechanical damage during installation or use.

[0021] like Figures 1 to 6 As shown, the utility model is a combined overhead insulated conductor. When it is working, in rainy and snowy weather, snow falls on the upper surface of the convex ring 9. The arc-shaped convex ring 9 can make the snow slide easily, reduce the amount of snow falling on the conductor, and reduce the burden on the conductor. When the snow melts and it rains, water flows in the groove 10, preventing water from flowing on the surface of the cable rubber sheath 5. After the water flows to the bottom of the groove 10, it drips directly downward. When the conductor is erected, the clamp ring 11 is placed in a fixed position, the connecting cap 13 is buckled between the two fixing plates 12, the bolt is turned, and the clamping plate 15 is pushed by the screw 14 to make the two fixing plates 12 close to each other, so that the clamp ring 11 is installed on the conductor, the contact area between the conductor and the overhead insulator is increased, and the conductor is prevented from sliding on the insulator.

[0022] The insulating layer 2 and insulating filling 4 of the combined overhead insulated conductor of the utility model are purchased on the market, and technicians in this industry only need to install and operate them according to the accompanying instruction manual without the need for creative work by technicians in this field.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
