When the cable tray is installed horizontally, the support span is generally 1.5-3m, and the spacing between fixed points is not more than 2m when laid vertically.

4.2橋架應平整，無扭曲變形，內壁無毛刺，各種附件齊全

4.2 The bridge should be flat, without distortion or deformation, with no burrs on the inner wall, and all accessories complete

4.3橋架接口應平整，接縫處應緊密平直。槽蓋裝上后應平整，無翹角，出線口的位置準確。

4.3 The bridge interface should be flat, and the joints should be tight and straight. After installing the slot cover, it should be flat, without any warping angles, and the position of the outlet should be accurate.

4.4在吊頂內敷設時，如果吊頂無法上人時應留有檢修孔。

4.4 When laying inside the suspended ceiling, if it is not possible to access people, an access hole should be left.

4.5橋架的所有非導電部分的鐵件均應相互連接和跨接，使之成為一連續導體，并做好整體接地；每段橋架之間的接地跨接采用編織銅線。

4.5 All non conductive parts of the bridge should be interconnected and bridged to form a continuous conductor, and the overall grounding should be done; The grounding jumper between each section of the bridge is made of braided copper wire.

4.6橋架經過建筑物的變形縫時，橋架本身應斷開，槽內用連接板搭接，不需固定。保護地線和槽內導線應留有補償余量。直線段鋼制橋應認真執行安全施工規章制度加強對施工人員管理，落實安全施工技術措施，檢查和督促施工人員安全作業，做到安全、文明施工。

4.6 When the bridge passes through the deformation joint of the building, the bridge itself should be disconnected, and the groove should be overlapped with a connecting plate without the need for fixation. Compensation allowance should be left for the protective ground wire and the wire in the slot. Straight section steel bridges should conscientiously implement safety construction rules and regulations, strengthen the management of construction personnel, implement safety construction technical measures, inspect and supervise the safe operation of construction personnel, and achieve safe and civilized construction.

1.2組織施工人員學習施工標準和熟悉施工圖紙，嚴格按照設計及有關規定、規范、標準要求進行施工，隨時檢查施工質量，發現問題及時整改。

1.2 Organize construction personnel to learn construction standards and familiarize themselves with construction drawings, strictly follow the design and relevant regulations, specifications, and standard requirements for construction, inspect construction quality at any time, and promptly rectify any problems found.

1.3對施工現場搭設腳手架、并架和施工現場使用的電氣、機械設備、安全防護裝置應符合相關安全規定并驗收合格后才能使用。施工人員在整個施工過程中應遵守下列規定：

1.3 The electrical, mechanical equipment, and safety protection devices used on the construction site should comply with relevant safety regulations and be inspected and accepted before use. Construction personnel should comply with the following regulations throughout the entire construction process:

2.1建議遵守和執行相關的安全生產、文明施工的管理制度并應接受建設單位監理人員的檢查監督。建議戴安全帽進入施工現場，高空作業建議系好安全帶。

2.1 It is necessary to comply with and implement relevant management systems for safety production and civilized construction, and accept the inspection and supervision of the construction unit's supervisory personnel. Safety helmets must be worn when entering the construction site, and safety belts must be fastened when working at heights.

2.3在控制室、開關室工作建議要有監護人員在場，并在斷電的情況下進行作業，應摘下手表、鑰匙、打火機、鋼筆等金屬物品，并戴絕緣手套，穿絕緣鞋。

2.3 When working in the control room and switch room, a supervisor must be present and work must be carried out in the event of a power outage. Metal items such as watches, keys, lighters, pens, etc. should be removed, and insulated gloves and shoes should be worn.

2.4需要整理排放電纜時，事前應征求監護人員的同意，并在監護人員監護下進行。

When it is necessary to arrange and discharge cables, the consent of the supervisor should be sought in advance and carried out under the supervision of the supervisor.
