[0002] A large number of electrical equipment and insulators in high-voltage electrical systems are installed outdoors, and pollution levels vary significantly across my country. Insulated busbars are essentially copper conductors with external insulation. Comparable to these are insulated aluminum busbars. Insulated copper busbars offer high current capacity (currently up to 12,000A), high mechanical strength, excellent insulation, and a wide range of applications, making them increasingly recognized and accepted by customers. However, previous insulated busbars have presented several issues, such as a lack of highly weather-resistant protective structures, which can easily damage them due to environmental factors during use. This reduces their service life and fails to meet current market demands. These issues have reduced the practicality and usability of insulated busbars.

[0003] The existing technology has the following problems:

[0004] 1. Existing high-weather-resistant insulated busbars are installed outdoors, especially in coastal areas or areas with severe heavy industrial pollution. Flashover accidents involving high-voltage electrical equipment or insulators often occur. Annual cleaning of outdoor insulators requires high-altitude operation, and disassembly and cleaning are not possible, making the device inconvenient to use.

[0005] 2. The existing high-weather-resistant insulating busbars are made of silicone rubber materials with low hardness and strength. They are easily damaged during the assembly process, causing damage to local umbrella pieces and the product being directly scrapped. Utility Model Content

[0010] A further improvement of the technical solution of the present utility model is that: the cross connector includes a shell, the inner wall of the shell is fixedly connected to a waterproof layer, and the inner wall of the waterproof layer is fixedly connected to an insulating layer.

[0011] A further improvement of the technical solution of the present utility model is that the inner wall of the insulating layer is connected to the outer wall of the core wire body, and both ends of the cross connector are in the shape of a bullet head.

[0012] A further improvement of the technical solution of the present utility model is that the core wire body includes a heat shrink protective sleeve, the inner wall of the heat shrink protective sleeve is fixedly connected with a polypropylene filler, the interior of the polypropylene filler is fixedly connected with four groups of copper wires, and the interior of the polypropylene filler is fixedly connected with a grounding wire.

[0013] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0014] 1. The utility model provides a highly weather-resistant insulated busbar. The connecting base is connected to the bottom of the device, which plays a role in stabilizing and fixing the connection of the device.
