Kaiti_bChoose materials according to the use environment. Cable bridge trunking and its supports and hangers should be made of corrosion-resistant rigid materials when used in corrosive environments, or should be treated with anti-corrosion treatments to prevent corrosion. The treatment method should meet the requirements of the engineering environment and durability.
Kaiti_b Is there any fire protection requirement? If the cable tray is in a section with fire protection requirements, fire-resistant or flame-retardant board mesh and other materials can be added to the cable ladder tray to form a closed or semi-closed type structure, and measures such as painting fire-retardant coatings on the surface of the bridge and its supports and hangers are adopted. Its overall fire-resistant performance should meet the requirements of relevant national specifications or standards. In places with high engineering fire protection requirements, aluminum alloy cable trays should not be used.
Kaiti_b Select the filling rate according to strong and weak electricity. The width and height of the cable ladder should be selected to meet the requirements of the filling rate. The filling rate of the cable ladder is generally preferable for power cables. %~%, the control cable can be %~%, and it is advisable to reserve %~% margin for project development.
Kaiti_bThe load level should be greater than the budget level. When selecting the load level of the cable ladder, the operating uniform load of the cable tray should not be greater than the rated uniform load of the selected cable tray load level. If the actual span of the cable tray supports and hangers is not equal to , the working uniform load should meet the requirements.
Kaiti_b components must match. Under the condition that the various components and supports and hangers meet the corresponding load conditions, their specifications and dimensions should match the straight-line segment bend series of the pallet ladder frame.
Kaiti_b Large-span bridges need to be verified. For steel cable trays with a span greater than ? or aluminum alloy cable trays with a span greater than? or load requirements greater than the load grade, they should be carried out according to engineering conditions. Calculation or experimental verification of strength, stiffness and stability.
