What are the common specifications of the bridge? What are the specifications of the bridge?

The cable tray is mainly composed of brackets, brackets and equipment accessories, which can be used to erect the equipment independently, and all parts need to be galvanized, and can be installed outside the building or in the open air. It can also be laid on buildings and pipe gallery supports. Cable trays can be found in underground parking lots, factory buildings, and many other power supply environments where exposed wires need to be protected.

Common specification table of the bridge:

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: Traybed cable tray is a semi-sealed cable tray, which is very similar to the posture of trough cable tray, and it has a hole 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).

The common models of cable tray are divided into trough type, tray type and ladder type. It is a building material that can not only protect cables and wires from external corrosion, but also protect the safety of our electricity.

It is composed of brackets, brackets and installation accessories, the bridge frame in the building can be erected independently, and can also be laid on various buildings (structures) and pipe gallery supports, which should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance, all parts need to be galvanized, and installed in the bridge frame in the open air outside the building.

Cable tray model differences:

Trough cable tray: trough is a fully sealed cable tray, its shape is the same as the box, its shielding performance is very good, generally used in communications, computer rooms and other fields.

Tray cable tray: The shape of the tray is almost the same as that of the trough type, but it has a perforated bottom, so it will have a nice improvement in terms of heat dissipation.

Ladder bridge: The shape of the ladder bridge is very unique, just like a ladder, it is developed in accordance with the latest information at home and abroad, it has good heat dissipation, easy installation, low cost and other ......

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*

Specifications and models of cable trays.

FRP bridge is a kind of composite material, which has the advantages of good corrosion resistance, anti-permeability, good overall performance, strong impact resistance, large inner surface hardness, high finish, and no scaling. OS FRP tray is suitable for the laying of power cables with a voltage below 10 thousand volts, as well as indoor and outdoor overhead cable trenches and tunnels such as control cables, lighting wiring, pneumatic and hydraulic pipe cables.
