Langfang Yonghui Industry & Trade Co., Ltd.   

Product introduction of double dragon ladder type cable tray is based on domestic and abroad and our similar product improvement and. It has the advantages of light weight, low cost, other distinctive, convenient installation, cooling, air permeability etc.. It is suitable for big diameter cables laying, particularly applicable to high voltage power cables. The performance parameters of the bridge of Langfang cascade type cable tray ladder type cable tray ladder type cable bridge of Wen'an Hebei ladder type cable 1) cable tray, slot and hanger used in corrosive environment, should be made of rigid material resistant to corrosion, or take anti-corrosion treatment, anti-corrosion treatment should meet the engineering environment and durability requirements. 2) cable trays in fireproof requirement in the section, the cable ladder, tray add with refractory or flame properties of the plate, net material to form a closed or semi closed structure, and take on the bridge and the support surface coated with fireproof coating and other measures, the whole refractory properties shall meet the national requirements of relevant code or standard. 3) in fire engineering requirements of the higher places, should not be used for aluminum alloy cable bridge. 4) cable ladder width and height should be consistent with the fill rate requirements, cable ladder filling rate in general, power cable can be 40% ~ 50%, 50% ~ 70% of control cable is desirable, and the appropriate reserve 10% ~ 25% engineering development margin. 5) in the selection of load rating of the cable ladder, cable bridge work uniform load should not be greater than the selected cable bridge load rating rated uniform load, if the actual span hanger cable tray is not equal to 2m, then the uniform load shall meet the requirements. Use and maintenance of construction, installation points 1) to the cable bridge and raceway should be short, and should as far as possible along the wall, along the column or beam along laying. 2) according to the cable bridge and raceway to, put forward to civil engineering structure, professional installation hole in the wall, floor reserved holes and hanger, the embedded steel plate position and load. And should be coordinated with process engineering, plumbing and power professional. 3) ground inside concealed metal raceways, should cooperate closely with the civil engineering in the design, according to the different structural patterns and the layout of the building, reasonably determine the path and equipment selection. 4) the laying of cable should not be different voltage, different purposes in the same layer cable bridge in: (1) above 1kV and below 1kV and cable; (2) the same path to the double loop power cable level loading; (3) cable emergency lighting and other lighting; (4) the power, control system and telecommunication cables. If the cables of different grades in the same cable tray, intermediate should increase the partition. 5) do not need to consider additional concentrated load installation or maintenance in the engineering conditions, cable ladder, tray work uniform load uniform distribution calculation according to the dead weight of the cable. Other description) cable tray is unfavorable and the pipeline in parallel, when cannot avoid, cable tray location shall comply with the following provisions, or take the corresponding protective measures. (1) cable tray should have above corrosive liquids pipeline. (2) cable tray should be below the heating pipeline. (3) the combustible and explosive gas is heavier than air, cable tray should be in the pipeline. (4) the combustible and explosive gas lighter than air, cable tray should be in the pipeline.
