AI Technical Summary
Existing busbar trunking systems have issues with heat dissipation and operational stability, especially during high-current transmission. Heat in the central area is difficult to dissipate effectively, leading to temperature increases that affect service life and safety.
The T-shaped grounding conductor busbar trunking design is adopted, with the PE phase busbar centrally located and a raised heat dissipation structure added to the outside of the side plate. The busbars of each phase are rationally arranged and integrally formed using aluminum alloy or electrical copper profiles, with the surface covered with polyester film.
It improves the heat dissipation performance and electrical safety of busbar trunking, reduces temperature rise, extends service life, reduces manufacturing costs, and enhances grounding protection and electromagnetic interference protection.
