Description

Technical Field

[0001] This utility model relates to the field of through-wall busbar technology, specifically a through-wall busbar with a sealing structure. Background Technology

[0002] Busbar trunking, as a high-current transmission device, is widely used in power distribution systems in buildings, industrial plants, and other locations. During installation, busbar trunking often needs to pass through walls to achieve power connections between different areas.

[0003] Traditional through-wall installation methods typically require drilling a hole in the wall and then directly inserting the busbar trunking, which has the following technical drawbacks: 1. Lack of fixed structure: The busbar trunking lacks effective support and fixing devices between itself and the wall, and is only temporarily fixed by simple filling materials (such as fireproof putty). This makes the busbar trunking prone to displacement due to vibration or external force during long-term operation, affecting the stability of electrical connections and potentially causing safety hazards. 2. Insufficient sealing: The gap between the busbar trunking and the wall hole is difficult to completely seal. Dust, moisture or small animals may enter through the gap, which will accelerate the aging of the busbar trunking insulation, reduce its service life, and increase the risk of short circuit.

[0004] Therefore, we propose a through-wall busbar trunking with a sealing structure. Utility Model Content
