Selection of fire rating of cable tray:

在有防火要求的地段，濟南電纜橋架可通過在電纜梯、橋架內添加防火或阻燃板、網等材料，形成封閉或半封閉結構，并采取在橋架及其支吊架表面涂防火涂料等措施。整體耐火性能應滿足相關規范或標準的要求。在防火要求高的地方，不應使用電纜橋架。

In sections with fire protection requirements, Jinan cable tray can form a closed or semi closed structure by adding fireproof or flame retardant plates, nets and other materials in the cable ladder and tray, and take measures such as coating the surface of the tray and its supports and hangers with fire retardant coating. The overall fire resistance shall meet the requirements of relevant national codes or standards. Cable trays shall not be used in places with high fire protection requirements.

在相同規格下，阻燃電纜橋架比鋼制電纜橋架貴2.2倍，使用壽命是鋼制電纜橋架的5倍以上，重量比鋼制電纜橋架重百分之30。其使用壽命是鋼制電纜橋架的三倍多，重量與鋼制電纜橋架基本相同。

Under the same specification, flame retardant cable tray is 2.2 times more expensive than steel cable tray, its service life is more than 5 times that of steel cable tray, and its weight is 30% heavier than steel cable tray. Its service life is more than three times that of steel cable tray, and its weight is basically the same as that of steel cable tray.

電纜橋架的定期維護：

Regular maintenance of cable tray:

1.一般來說，電纜橋架可以每季度維護一次。用軟布擦去表面的灰塵后，用一種特殊的蠟拋光劑均勻地擦拭表面，過一會兒再用一塊干凈的軟布拋光，這是防潮的。五金配件和金屬手柄可以用較少的機油擦拭和干燥，因此它們可以靈活旋轉，防銹。

1. Generally speaking, the cable tray can be maintained once a quarter. After wiping the dust off the surface with a soft cloth, wipe the surface evenly with a special wax polishing agent, and then polish with a clean soft cloth after a while, which is moisture-proof. Hardware fittings and metal handles can be wiped and dried with less oil, so they can rotate flexibly and prevent rust.

2.避免放置在濕熱的地方，保持房間通風干燥。

2. Avoid placing in hot and humid places and keep the room ventilated and dry.

3.避免與腐蝕性液體接觸，如酒精和指甲油。

3. avoid contact with corrosive liquids such as alcohol and nail polish.

4.應使用干凈的軟布和專用保養蠟。

4. Clean soft cloth and special maintenance wax shall be used.
