Technical Field

[0001] The utility model relates to the technical field of copper busbars, in particular to a copper busbar with an insulating mounting sleeve. Background Art

[0002] Copper busbar generally refers to copper busbar, which is an indispensable conductive material for manufacturing motor windings, high and low voltage electrical appliances, switch contacts, and wires for power supply and distribution installation. Copper busbar is a major variety of copper processing materials. Copper busbar has high mechanical properties, good electrical conductivity, thermal conductivity, excellent corrosion resistance, electroplating properties, etc., and is widely used in the production of various power transmission and transformation, electrical equipment, etc. In the power field, an insulating mounting sleeve is usually installed on the outside of the copper busbar to protect the copper busbar. However, the existing insulating mounting sleeve has a poor sealing effect when penetrating the electrical cabinet for conductive installation, which easily causes dust or water vapor to enter the electrical cabinet through the gap between the copper busbar and the electrical cabinet.

[0003] When the copper busbar passes through the electrical cabinet for electrical conduction, the installation stability of the copper busbar is low, and it is inconvenient to use the installation mechanism to install the copper busbar between the electrical cabinet, which can easily cause the copper busbar to shift or shake. In addition, there is a gap between the copper busbar and the electrical cabinet, which can easily cause dust or water vapor to enter the equipment and damage the electronic components. Therefore, those skilled in the art provide a copper busbar with an insulating mounting sleeve to solve the problems raised in the above background technology. Utility Model Content
