Ladder cable tray is widely used in automobile, construction, chemical industry, machinery, petroleum, metallurgy, light industry, transportation, electric power and marine engineering and other fields, is now widely used in construction engineering is a kind of cable protection device. The relevant features are as follows:

For vertically installed cable trays, ladder cable trays or pallet structure trays should be selected. In public corridors or outdoor crossings across the street, the lowest cable tray is suitable for ladder cable trays with a protective plate at the bottom. Considering the safety load, the ladder cable tray is generally forbidden to be used as a pedestrian passage or a platform for standing people, in order to avoid safety accidents, if the ladder cable tray must be used as the above device, relevant reinforcement measures must be used to ensure it.

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).

Galvanized ladder tray: referred to as "ladder cable tray.""It has a unique appearance like a ladder to change its shape, and is welded with a crossbar in the middle to reinforce the support, so that it is light weight, low cost, extremely strong bearing capacity, and good air permeability, and is suitable for laying cables with relatively large diameters in general, especially for the laying of high and low power cables.

<> ladder cable tray includes: spray ladder bridge, aluminum alloy ladder bridge, zinc-plated ladder bridge, fire ladder bridge, etc.

The hot-dip galvanized cascade cable tray is specified as follows:

The cascade hot-dip galvanized cable tray can be recognized by everyone, indicating that it has unique advantages, first of all, the main thing is that it has good corrosion resistance, long service life, stable quality and high degree of production industrialization. Therefore, it is more widely used in places with large corrosive environments.

Cascade bridge stands out in many kinds of bridge, is designed by the lack of special or industry people in combination with domestic and foreign data on continuous improvement, it has light weight, low cost, unique shape, easy installation, heat dissipation, good ventilation and other characteristics are the needs of the public. In the laying of cables with large diameters, he is more suitable for the laying of high-voltage and low-voltage power cables. The setting of galvanized anti-corrosion materials adds a different color to the cable tray and brings new business opportunities to the cable tray industry.

A cable is made of one or more conductors that are insulated from each other and an outer insulating protective layer that transmits electricity or information from one place to another. A yard is usually a rope-like cable made up of several or groups of wires (at least two in each group), each of which is insulated from each other and is often twisted around a center, with a highly insulating covering over the entire outskirt. The cable has the characteristics of internal energizing and external insulation.
