What are the commonly used specifications for metal cable trays?

The type of cable tray mainly depends on the weight of the cable and the use environment and other factors, and the following provides us with some commonly used cable tray types on the market as a reference:

Trough cable tray: A trough cable tray is a hermetically sealed cable tray, box-like shape, used to lay cables.

Ladder cable tray: It looks like a ladder shape together, and the center is welded with a crossbar to reinforce the support, which makes it light weight, low cost, extremely strong bearing capacity and good air permeability.

<> Tray Cable Tray: The tray cable tray is a semi-sealed cable tray, which is very similar to the posture of the trough cable tray, with holes in the bottom for heat dissipation.

The following is a guide to the commonly used standards in the market

The standard is suitable for: trough tray (C), ladder tray (T), tray tray (P) (special standards can be customized by contact).

Thickness: non-standard) national standard).

Usually the models of cable tray are divided into: trough type, tray type, ladder type or shouting hunger.

The different materials of the cable tray are divided into: galvanized tray seepage, stainless steel 304 bridge, aluminum alloy 1060 bridge.

The surface treatment process is divided into: fireproof paint, electrostatic spraying, hot-dip galvanizing (hot-dip galvanizing) Common specifications are: (wide shirt back * height * thickness: national standard thickness) 300mm * 100mm*

400mm*100mm*

500mm*100mm*

600mm*200mm*

800mm*200mm*

1000mm*150mm*

1200mm*200mm*, etc.

Stainless steel tray, cable tray conventional production length tray is currently widely used in the construction industry, tray model, galvanized tray: 4000mm-9000mm

The cable tray can produce specifications and step trays, mainly including trough trays.

Metal cable tray.

Model: Trough cable tray.

Tray cable tray.

Ladder cable tray.

Common specifications of metal cable tray: 80mm*60mm, 100mm*50mm, 150mm*100mm, 200mm*100mm, 300mm*100mm

Specifications and models of cable trays.

Usually the models of cable tray are divided into: trough type, tray type, ladder type.

The different materials of the cable tray are divided into: galvanized tray, stainless steel 304 tray, aluminum alloy 1060 tray.

The surface treatment process is divided into: fireproof baking paint, electrostatic spraying, hot-dip galvanizing (hot-dip galvanizing) Common specifications are: (width * height * thickness is: national standard thickness).

300mm*100mm*

400mm*100mm*

500mm*100mm*

600mm*200mm*

800mm*200mm*

1000mm*150mm*

1200mm*200mm*, etc.

Trough cable tray is a classified model of tray, because there are usually 3 types of tray: trough, ladder, and tray.

The specification representation of the trough cable tray is as follows; The width of the tank box + the height of the box + the thickness of the tank + the length of the tank.

Example: 200*100*, which means: 200mm width + 100mm height + thickness + 2 meters.

The common specifications of trough cable tray are:

Common references for cable tray specifications:

200mm*100mm

300mm*100mm

400mm*150mm

400mm*200mm

500mm*150mm

600mm*200mm

The difference between cable tray and metal trunking: cable tray is used to lay power cables and control cables, and metal trunking is used to lay wires and communication cables. The bridge is relatively large, and the trunking is relatively small.

The bending radius of the bridge is relatively large, and most of the trunking is bent at a right angle. The span of the bridge is relatively large, and the trunking is relatively small; The fixing and installation methods are different. In some places, the tray is uncovered, and the trunking is almost entirely closed with a cover.

The trunking is used for wiring wires, and the tray is used for routing cables. The use environment is different, the trunking is often not able to be used in the open air, while the bridge can.

Usually the models of cable tray are divided into: trough type, tray type, ladder type.

The commonly used materials of cable tray are divided into: galvanized, stainless steel, and aluminum alloy tray surface treatment process is divided into: fireproof, spraying, and hot-dip galvanizing.

Common specifications are: (width * height * thickness is: national standard thickness) 300mm*100mm* 400mm*100mm* 500mm*100mm* 600mm*200mm*

The width and height of the bridge are selected according to the following table, and should meet the requirements of the cable filling rate does not exceed the specified value of the relevant standard specifications, the power cable can take 40-50%, the control cable can take 50-70%, and the need to leave 10-25% of the formula development margin.

If Sony is a metal cable tray, there are many specifications and models of it, and we can't tell for a while.
