Scope and cable tray installation considerations
1, to determine the environment: There are three general conditions: corrosive environment, a normal environment, the special environment.
2, determine the trend: According to most cable direction can be along the wall in the room, columns, beams, floor walking, can go outdoors willing to do along the pipeline.
3. Select the tray: According to the load and the load curve environment cable tray installation at, and bridge as the basis to determine the type and specifications of the bridge.
4, it is determined according to a way bridge and installation of the cable to the environment.
First, the scope of application of cable tray
XQJ series cable tray suitable for voltages below 10 volts of power cables control cable wiring and other indoor lighting, outdoor overhead laying or cable trenches and tunnels.
Second, the structural characteristics of the cable tray installation
XQJ series cable bridge has a wide variety, wide application, high strength, light structure, low cost, simple construction, flexible wiring, installation standards, characteristics of beautiful appearance, improve your technical department, and expanded cable, easy maintenance and overhaul to bring .
XQJ series cable tray installation can be adapted to local conditions. May vary depending on the process piping overhead laying the floor beam under the ceiling, indoor and outdoor walls, column wall, tunnel, cable trench side wall mounted, open-air column can also be laid on both sides of symmetry.
XQJ series cable tray can be horizontal, vertical laying, the corner, T-shaped, cross-shaped branch, adjustable width, increase, become lighter.
Third, the cable between the cable bridge level arrangement with the interlayer distance
1, cable tray weak current level arrangement should be controlled at the top, followed by the general control cables and low voltage power cables, high voltage power cables down in order of priority. This arrangement is conducive interference shielding, cooling power cables, to facilitate construction.
2, cable tray between layers layer distance:
Control Cable ≥200mm
Power cable ≥300mm
Mechanization cabling ≥400mm
