Enclosed Busbar
Enclosed Bus Duct (also known as Enclosed Busbar) is a bus system consisting of a metal shell (steel plate, aluminum plate, or fireproof board) for protection, conductive bars (copper bars, aluminum bars, or copper-aluminum composite materials) as current carriers, insulation materials, related fixings, and accessories. It includes phase-separated enclosed busbars, common box busbars, and cable busbars, widely used in power plants, substations, and industrial and civil power sources.

Product Features:
❖ Made with an aluminum-magnesium alloy shell, which is lighter, offers better sealing and heat dissipation, and features a special structure with sufficient mechanical strength to support and protect the busbar system.
❖ The "connector set method" is faster and more efficient.
❖ Special connectors simplify busbar connections and speed up the installation process.
❖ Advanced insulating materials ensure higher safety.
❖ The conductor surface has a multi-layer B-grade (130°C) polymer resin film with a thickness of up to 0.5mm.
Compliant Standards:
❖ GB7251.2-2006
❖ GB7251.2-2005
❖ JB/T9662-1999
