Cable trays installation, important is carried out in accordance with the provisions of the specification

1, laying cable trays in major pipelines are more concentrated technical and when the upper ceiling of the corridor, bridges and water supply pipes, the distance between the air duct cannot meet the requirements of specification, when maintenance is required, inconvenient to open the tray cover. During installation, if not ahead of major coordination and the relevant technical data of the pipeline, it is difficult to control. On this work, we can draw a sketch in advance, relevant technical data of the integrated pipeline and the bridge's location, between the size of profile, adjusting the distance between the professional pipeline, prevent the occurrence of disease.

2, fill the tray cable rate exceeds the specification value. In construction drawings in the, most common of only plane layout figure, even has profile figure also not is perfect, according to steel business cable Bridge frame design specification 3rd. 8.1 article provides: its design content has: 1, and Bridge frame system of plane layout figure; 2 Bridge frame system of about profile Figure; 3 Bridge frame system by needed tray, and ladder frame line paragraph bent pass, and support hanging frame specifications and number of name fine table and necessary of description; 4 has special requirements of non-standard technology description or Cheung figure. By design is not perfect enough and other reasons, causing local placing cables too much, even fully loaded, does not conform to specification 3.2. Article 1: cables fill rate should not exceed the standard values, power cable 40%, 50% control cable requirements. In this regard, the supervisory personnel should be ex ante preventive measures, strict construction is not purchasing before the bridge, master of electrical engineering systems function on each bridge cables within the rack number and cable cross-sections and do accurate statistics, found that the problem should be in conjunction with the design in time change the specifications for bridge, effective control of the quality problems occur.
