Cable tray is a rigid structural system consisting of straight sections, bends, components, and support arms (arm brackets), hangers, etc. of the tray, which have tightly connected supporting cables.
Tray type cable trays have the advantages of light weight, large load, beautiful appearance, simple structure, and convenient installation. It is suitable for both the installation of power cables and the laying of control cables. The surface treatment of tray type cable trays can be divided into two types: plating and painting, and special anti-corrosion treatment can be applied in heavily corrosive environments. Tray type cable trays are equipped with protective covers, and all accessories are common to tray and trough type cable trays.
Tray type cable trays can be divided into perforated trays, perforated trays, and assembled trays based on their structure.
(1) A perforated tray is a groove shaped component composed of a bottom plate and a side plate with holes, or a component made by punching and bending a whole steel plate.
(2) A perforated tray is a groove shaped component composed of a bottom plate and side edges or made of an entire steel plate.
(3) Assembled pallets are components that are connected to a pallet by bolts or plugs, which are suitable for any combination of perforated components on the engineering site.
They are all used for laying cables. When low-voltage cables and control cables share the same tray or ladder, a ladder or tray with a partition in the middle should be selected.
1. Are slot type cable trays and perforated tray type cable trays the same product?
2. Can both slot type cable trays and perforated tray type cable trays be used for laying power cables?
Both trough type through cable trays and perforated tray type cable trays can be used for laying power cables; The cross-section and structural form are different.
Closed cable trays, uncovered trays, and ladders all belong to cable trays. The three types of cable trays have different structural forms and some performance differences, such as the best protection of the trough type and the worst of the ladder, but the opposite is true for ventilation and cooling.
The difference between slot type cable tray and tray type cable tray (use)
Slot type cable trays are mainly used for laying wires and cables with a small cross-section but a large quantity. Tray type cable trays are mainly used for laying power cables with a large cross-section and a small quantity.
Slot type cable trays are most suitable for laying computer cables, communication cables, thermocouple cables, and control cables for highly sensitive systems in slot type cable trays.
Tray type cable tray is the most widely used type in petroleum, chemical, light industry, television, telecommunications, and other fields.
Slot type cable trays are commonly used for instruments, while ladder type and tray type cable trays are commonly used for electrical cables. Among them, power cables generally only use ladder type cable trays. Tray type cable trays are generally used for laying control cables. Mainly based on the heat dissipation performance of the cable.
The difference between slot type cable tray and tray type cable tray (appearance)
Slot type cable tray is a fully enclosed cable tray. Tray trays generally refer to slotted trays with holes. Due to the opening of heat dissipation holes, the thickness of the tray type bridge board is thicker.
The difference between slot type cable tray and tray type cable tray (performance)
The trough type cable tray is a 360 degree fully enclosed structure, with the main function of shielding interference and resisting corrosion. It has good effects on controlling cable shielding interference and protecting cables in heavily corrosive environments.
The surface treatment of tray type cable trays can be divided into three types according to user needs: galvanizing, electrostatic spraying, and hot galvanizing. In heavily corrosive environments, special anti-corrosion treatment can be applied.
There are many waist shaped holes at the bottom of the tray tray to facilitate heat dissipation.
