Installation specifications and requirements for fiberglass cable trays

 

Fiberglass cable trays are suitable for laying power cables below 10kV, indoor and outdoor overhead cable trenches, such as control cables, lighting lines, pneumatic, hydraulic pipeline cables, etc. Fiberglass cable tray has the characteristics of wide applicability, high strength, light weight, reasonable structure, low cost, long service life, strong corrosion resistance, simple construction, flexible wiring, and beautiful installation standards, bringing convenience to your technical transformation, cable expansion and maintenance.

Installation specifications for fiberglass cable trays:


 

1. Aerial laying of process pipelines;

2. Hoisting under floors and beams;

3. Indoor and outdoor exterior wall side installations, column walls, and cable trench walls can also be installed on outdoor columns or bridge piers.
 

When hoisting large multi story bridges, I-shaped steel columns should be arranged symmetrically on both sides as much as possible. Fiberglass bridges can be laid horizontally or vertically, with corners, T-shaped, and cross shaped branches. Width, height, and diameter can be adjusted. Cable tray is a cable laying device that standardizes, serializes, and generalizes the laying of wires, cables, and pipelines. Basic category: Slot type cable tray is a fully enclosed cable tray that is more suitable for preventing interference from high sensitivity system control cables such as computer cables, communication cables, thermocouple cables, etc. The cable protection effect is good in heavily corrosive environments. Cable trays are generally suitable for laying large-diameter cables, especially for laying high and low-power cables.

Installation requirements for fiberglass cable trays:
 

1. Fiberglass cable tray is a supporting project for cable wiring engineering. The installation requirement is to determine the direction: based on the layout of the building plan, combined with pipeline settings, ease of maintenance, and density of cable routing, determine the optimal wiring method for cable trays. In the room, try to stand upright along the walls, columns, beams, and floors of the building.

2. Load calculation: Calculate the total cable force and unit length on the longitudinal section of the main cable tray.

3. Determine the width of the cable tray: Arrange according to the number, diameter, and spacing of the cables. Determine the type, diameter, and specifications of the cable tray, the length of the support arm, the length and spacing of the columns, and the width and number of layers of the cable tray.

4. Determine installation method: Determine the fixing method of fiberglass cable tray based on on-site conditions, and choose hanging, vertical, side wall, or hybrid. Connectors and fasteners are usually supplied together. In addition, corresponding cover plates should be selected based on the structure of the bridge.

5. If used in conjunction with power cable trays, the direct side of the power cable should be separated from the weak current cable by partitions.

6. When weak current cables share cable trays with other low-voltage cables. The weak current cables of weak current systems with external anti-interference layers should be strictly selected to avoid mutual interference.
