在電力傳輸系統裏，匯流排的類型對供電效果影響重大。裝甲型匯流排和模鑄作為常見類型，在多個方面存在明顯差異。In the power transmission system, the type of busway has a significant impact on the power supply effect. As common types, the compact busway and the cast busway have obvious differences in many aspects.
結構上，裝甲型匯流排採用緊湊的 “三明治” 構造。由銅或鋁導體組成，導體間靠絕緣材料隔離，外包鋁合金外殼，兩側常設有散熱片。這種結構利於散熱，且連接頭可靈活檢修、調整走向並增加插介面。模鑄則是將導體澆注在絕緣材料（如環氧樹脂）中形成一體化結構，防護性能極佳。In terms of structure, the compact busway adopts a compact "sandwich" structure. It is composed of copper or aluminum conductors, which are isolated by insulating materials, and is enclosed by an aluminum alloy casing. Heat dissipation fins are often provided on both sides. This structure is conducive to heat dissipation, and the connection joints can be flexibly overhauled, the routing can be adjusted, and socket interfaces can be added. The cast busway, on the other hand, forms an integrated structure by casting the conductors in insulating materials (such as epoxy resin), and has excellent protection performance.
性能表現各有特點。散熱與載流方面，裝甲型匯流排因良好的散熱設計，載流能力強，能滿足大功率設備需求；模鑄因絕緣材料導熱性差，散熱受限，載流相對較弱。防護性能上，裝甲型匯流排防護等級一般為 IP54 - IP66，適用於多數常規環境；模鑄防護等級高達 IP68，防水、防塵、防腐蝕，能在惡劣環境中穩定運行。檢修維護時，裝甲型匯流排連接頭便於檢修，後期調整方便；模鑄連接頭固定，檢修困難，安裝工藝要求高。The performance characteristics also vary. In terms of heat dissipation and current-carrying capacity, due to the good heat dissipation design, the compact busway has a strong current-carrying capacity and can meet the power demands of high-power equipment. For the cast busway, because the thermal conductivity of the insulating material is poor, heat dissipation is limited, and its current-carrying capacity is relatively weak. In terms of protection performance, the protection level of the compact busway is generally IP54 - IP66, which is suitable for most conventional environments. The protection level of the cast busway is as high as IP68, which is waterproof, dustproof, and corrosion-resistant, and can operate stably in harsh environments. During maintenance, the connection joints of the compact busway are easy to overhaul, and subsequent adjustments are convenient. The connection joints of the cast busway are fixed, making maintenance difficult and requiring high installation technology.
應用場景也各有側重。裝甲型匯流排適用於大型建築和工業廠房等常規場合。在大型商業綜合體，能滿足眾多樓層用電，且節省空間、方便改造；工業廠房中，可承受大電流，快速排除故障，保障生產。模鑄多用於惡劣環境場所，如化工、海邊，能抵禦腐蝕；以及高潔淨度要求場所，像電子晶片製造車間，防止灰塵影響生產。The application scenarios also have different focuses. The compact busway is suitable for conventional scenarios such as large buildings and industrial plants. In large commercial complexes, it can meet the power needs of multiple floors, save space, and is convenient for renovation. In industrial plants, it can withstand large currents, quickly troubleshoot faults, and ensure production. The cast busway is mostly used in harsh environment scenarios, such as chemical plants and coastal areas, to resist corrosion. It is also used in scenarios with high cleanliness requirements, such as electronic chip manufacturing workshops, to prevent dust from affecting production.
