Precautions for AAAC Conductor Tray Installation

AAAC conductor bridge constructed from the aluminum material tray or ladder runs through the elbow accessories and hangers etc. general assembly for supporting cable has sustained structural rigidity ladder: a ladder cable tray components directly supporting cable referred to by the two longitudinal sides of the trapezoid parts consisting of several roots rang hole tray: a hole directly supporting cable trough cable tray components referred to by a perforated cable tray bottom and sides consisting of or by a single block of the aluminum plate after punching a hole in the bottom bend into the groove part nonporous tray.

Install cable tray should be noted: cable tray should have sufficient rigidity and strength to provide reliable support for cable; cable tray and technology co-rack installation rack, power cable tray should be arranged on one side of the tube holder. The cable bridge to the floor, from the bottom of the beams or other obstacles, shall be not less than 300mm. A cable bridge for pedestrian use should not. The cable tray should be reliable ground; normal media properties should be laid on a separate grounding line when If the cable tray is the grounding line, should check the cross-sectional area of the cable bridge meets the ground fault current requirements. And should ensure that all connection points, good electrical path, for example, in the hinge plate, and other multi-section two-way connections need to add a jumper.

1. For special shape bridge, the spot size is measured cross to material suppliers, by the supplier in accordance with the size of production, reducing on-site processing. Bridge material, type, thickness, and accessories to meet the design requirements.

2. Before cable tray installation, you must coordinate with the professional and avoid the large-diameter fire hose, sprinkler pipes, hot and cold water, drain and air-conditioning, and ventilation equipment conflict.

3. The bridge is lifted to a predetermined position, and the bracket bolted, in the corner size should be carefully checked, the bridge should be consistent with the building slope, bridge building in the arc-shaped wall, which arc should be the building agreement. Between the bridge and the bridge connecting plate, connecting bolt using round head bolts, round head on the inside of the bridge. Bridge the gap must meet the design requirements, to ensure that a system of integral bridges.

4. Deformation of bridge building across the enterprise standard should be "aaac conductor tray installation process," good joints treatment, steel bridge line segment exceeds 30m, expansion and contraction compensation device should be set.
