在電氣布線系統中，橋架如同線纜的 “高速公路”，而各類配件則是這條路上不可或缺的 “交通樞紐” 與 “設施”。它們看似不起眼，卻在支撐、連接、轉向、防護等環節發揮著關鍵作用，共同保障線纜系統的有序運行。

　　In the electrical wiring system, cable trays are like a "highway" for cables, and various accessories are indispensable "transportation hubs" and "safety facilities" on this road. They may seem inconspicuous, but they play a crucial role in supporting, connecting, turning, and protecting the cable system, working together to ensure its orderly operation.

　　轉向類配件：讓線纜 “靈活拐彎”

　　Steering accessories: allowing cables to bend flexibly

　　彎頭是橋架轉向的核心配件，常見有 90°、45° 等規格，用于改變橋架的敷設方向。當線纜需要繞過梁柱、墻角或調整走向時，彎頭能使橋架形成平滑過渡，避免線纜因直角彎折而受損。例如在建筑走廊拐角處，安裝 90° 彎頭可讓橋架貼合墻體走向，既美觀又保護線纜絕緣層。

　　Elbows are the core components for turning cable trays, commonly available in specifications such as 90 ° and 45 °, used to change the direction of cable tray installation. When cables need to be routed around beams, columns, corners, or adjusted in direction, bends can create a smooth transition for the cable tray, avoiding damage to the cables due to right angle bending. For example, installing a 90 ° bend at the corner of a building corridor can allow the cable tray to conform to the direction of the wall, which is both aesthetically pleasing and protects the cable insulation layer.

　　三通 / 四通則承擔著線纜分支與匯合的功能。三通用于 “一進二出” 或 “二進一出” 的分支場景，如從主橋架向兩側房間分線；四通則適用于 “十字型” 交叉布線，常見于機房等線纜密集區域，讓不同方向的線纜通過同一節點有序分流，避免混亂纏繞。

　　The three-way/four-way principle is responsible for the function of cable branching and merging. Three commonly used in branching scenarios of "one in, two out" or "two in, one out", such as branching lines from the main bridge to the rooms on both sides; The four general rules apply to "cross type" cross wiring, commonly found in cable intensive areas such as computer rooms, allowing cables from different directions to be orderly diverted through the same node, avoiding chaotic entanglement.

　　支撐與固定類配件：給橋架 “穩穩的幸福”

　　Supporting and fixing accessories: providing "stable happiness" to the bridge frame

　　支架是橋架的 “骨骼”，根據安裝方式分為懸吊式、側壁式、托臂式等。懸吊式支架通過膨脹螺栓固定在天花板或鋼結構上，用吊桿懸掛橋架，適合空曠區域的懸空敷設；側壁式支架則固定在墻體或立柱上，支撐水平或垂直走向的橋架，常用于室內靠墻布線。

　　The bracket is the "skeleton" of the bridge, which can be divided into suspended, side wall, and arm supported types according to the installation method. The suspended bracket is fixed to the ceiling or steel structure through expansion bolts, and the cable tray is suspended by a suspension rod, suitable for hanging in open areas; Side wall brackets are fixed on walls or columns to support horizontal or vertical cable trays, commonly used for indoor wiring against walls.

　　連接件包括連接片、螺栓螺母等，用于橋架節段之間的固定連接。的連接片能確保橋架整體的剛性與導電性，防止因振動導致的松動，同時保證接地系統的連續性，避免漏電風險。例如在長距離橋架敷設時，每隔一定距離需用連接片將多段橋架連成整體，增強結構穩定性。

　　Connectors include connecting pieces, bolts and nuts, etc., used for fixed connections between bridge segments. High quality connectors can ensure the overall rigidity and conductivity of the bridge, prevent loosening caused by vibration, and ensure the continuity of the grounding system to avoid the risk of leakage. For example, when laying long-distance cable trays, connecting pieces are needed at regular intervals to connect multiple sections of the tray as a whole and enhance structural stability.

　　防護與封閉類配件：為線纜 “遮風擋雨”

　　Protective and enclosed accessories: providing "wind and rain protection" for cables

　　蓋板覆蓋在橋架上方，是線纜的 “防護罩”。它能阻擋灰塵、水汽、雜物進入橋架內部，避免線纜因積塵受潮而老化，同時防止人為觸碰或外物撞擊導致的線纜損傷。在機房、地下室等環境中，蓋板還能減少電磁干擾，保障信號線纜的傳輸質量。

　　The cover plate covers the cable tray and serves as the "protective shield" for the cables. It can prevent dust, water vapor, and debris from entering the interior of the cable tray, avoiding cable aging caused by dust and moisture accumulation, and preventing cable damage caused by human touch or external object impact. In environments such as computer rooms and basements, cover plates can also reduce electromagnetic interference and ensure the transmission quality of signal cables.

　　隔板用于橋架內部的空間分隔，可將不同類型的線纜（如強電與弱電、高壓與低壓）分區域敷設，避免相互干擾。例如在綜合布線系統中，用隔板將電源線與網絡線分開，既能保證信號穩定，又能降低隱患。

　　The partition is used to separate the space inside the cable tray, allowing different types of cables (such as strong and weak electricity, high and low voltage) to be laid in different zones to avoid mutual interference. For example, in a comprehensive cabling system, using partitions to separate power lines from network lines can ensure signal stability and reduce safety hazards.

　　特殊場景專用配件：應對 “疑難雜癥”

　　Special accessories for special scenarios: to deal with "difficult and complicated problems"

　　變徑接頭用于連接不同規格的橋架，如從寬橋架過渡到窄橋架，或從高橋架轉向低橋架，確保線纜平滑過渡，避免因截面突變導致的線纜擠壓。在樓層間橋架上下穿越時，變徑接頭可匹配不同樓層預留孔的尺寸，保證布線順暢。

　　Variable diameter connectors are used to connect cable trays of different specifications, such as transitioning from wide to narrow trays, or from high to low trays, to ensure smooth cable transitions and avoid cable compression caused by sudden cross-sectional changes. When crossing the bridge between floors, the variable diameter joint can match the size of the reserved holes on different floors to ensure smooth wiring.

　　防火封堵件在消防要求高的場所必不可少，包括防火泥、防火板等。當橋架穿越防火墻或樓板時，用防火封堵件填充縫隙，能阻止火焰和煙霧蔓延，滿足建筑防火規范。例如在高層建筑中，每層樓板處的橋架縫隙都需用防火材料密封，形成防火分區。

　　Fireproof sealing components are essential in places with high fire safety requirements, including fireproof mud, fireproof boards, etc. When the bridge passes through firewalls or floor slabs, filling the gaps with fireproof sealing components can prevent the spread of flames and smoke and meet building fire safety regulations. For example, in high-rise buildings, the gaps between the cable trays at each floor slab need to be sealed with fire-resistant materials to form fire compartments.

　　細節輔助類配件：“小身材大作用”

　　Detail auxiliary accessories: "Small body, big effect"

　　接地跨接線是橋架接地系統的關鍵，通過銅編織帶或導線連接橋架各段，確保整體接地導通，防止靜電積累和漏電事故。尤其在易燃易爆場所，可靠的接地能有效避免電火花產生。

　　Grounding jumper wire is the key to the bridge grounding system, which connects each section of the bridge through copper braided tape or wire to ensure overall grounding continuity and prevent static electricity accumulation and leakage accidents. Especially in flammable and explosive places, reliable grounding can effectively prevent the generation of electric sparks.

　　線纜固定夾用于橋架內部線纜的整理，將線纜按束固定，避免晃動磨損，同時讓布線更整齊美觀，方便后期維護檢修。在數據中心等需要頻繁增減線纜的場景中，固定夾可快速調整線纜布局，提升管理效率。

　　Cable fixing clips are used for organizing cables inside cable trays, fixing them in bundles to avoid shaking and wear, and making the wiring more neat and beautiful, facilitating later maintenance and repair. In scenarios such as data centers that require frequent addition or removal of cables, fixed clips can quickly adjust cable layout and improve management efficiency.
