For today's rapidly developing network information era, we have also achieved more results in the development and application of various network technologies. For example, the development and promotion of grid bridges is a good example. So what are the advantages of this type of bridge system?

A type of fault: the entire cable is burned out or a phase is burned out. This type of fault causes the current relay on the power distribution cabinet to act, and the cable is damaged seriously at the fault.

1. The cascade cable tray, CQ1-T cascade cable tray is based on the improvement of the design at home and abroad. It has the advantages of light weight, low cost, unique modeling, easy installation, good heat dissipation and good ventilation. It is suitable for the laying of cables with larger diameter in general, and for the laying of high and low voltage power cables.

In our lives, the use of steel trough bridges is actually more, mainly because of these advantages:

1. The grounding wire must have a transparent soft plastic outer sheath. When the temperature changes, the soft plastic outer sheath will not deform or become hard. The bottom of the insulated handle of the ground wire should be sealed. The ground wire manufacturer introduces that when the ground wire chuck and the wire are connected, there should be sufficient tightness and war area, and the ground wire guarantees excellent warfare. The ground wire clamp and ground clamp shall have sufficient strength.

Although the grid cable tray is easy to maintain in use, the daily maintenance work is still important during use. What are the specific maintenance tasks? Next, let's take a look at the relevant instructions for the daily maintenance work of the grid cable tray. Grid bridges have been used in many places in succession. Grid bridges are the same as other mechanical devices. The daily maintenance of grid cable bridges is equally important and requires good maintenance. If improper maintenance is used, it will affect the use. Effect, and will also reduce the service life of the grid bridge, so we must pay attention to correct maintenance in the process of use.

In fact, the use of galvanized metal bridges is not only necessary for the use of the bridge itself, we actually need a lot of accessories when installing.

We all know that the main function of longitudinal earthquake support is to mitigate the damage caused by earthquakes. Their seismic fortification strength can reach six to nine levels. There are many brands that can produce longitudinal seismic support for bridges. What kind of anti-seismic support and hanger manufacturers are selected for those in need?

1. Clean and sweep. A good working environment is the key to whether the work can be carried out in an orderly and effective manner, so we must clean up the line pipe in advance, and clean up the dirt and water in the pipe.

Due to changes in the ambient temperature, the steel cable tray will expand and contract. The outdoor cable tray is greatly affected by temperature. For example, the maximum ambient temperature is 40 ℃ and the minimum temperature is -20 ℃, then the maximum shrinkage of the cable tray is calculated as follows:

1. When the cable network that needs to be shielded from electrical interference or the external protection (such as corrosive liquid, flammable dust, etc.) is required, the (FB) slot type composite anticorrosive shielded cable bridge (with cover )

In the section with fire protection requirements, the cable ladder frame, tray can be added with fire-resistant or flame-retardant plates, nets and other materials to form a closed or semi-closed structure, and the surface of the bridge and its support and hanger are painted Brush fireproof coating and other measures. Its overall fire resistance should meet the requirements of relevant codes or standards. In places with high fire protection requirements. Aluminum alloy cable trays should not be used. Cable lines that need to be shielded from electromagnetic interference. Or when there is protection against external shadows such as outdoor sunshine, oil, corrosive liquid, flammable dust and other environmental requirements. Non-porous tray cable tray should be used.

We all know the importance of the application of cable trays in the power system and the guarantee of the normal operation of our lives. Due to the different application environments, the types of bridge trays are also different. The tray-type cable trays are petroleum, chemical, light industry, TV, telecommunications The most widely used. It has the advantages of light weight, large load, beautiful shape, simple structure and convenient installation. Today we will take a look at the environmental requirements for the installation of tray cable trays:

Aluminum alloy bridge frame forged aluminum alloy can be divided into aluminum silicon alloy, aluminum copper alloy, aluminum magnesium alloy, aluminum zinc alloy and aluminum rare earth alloy according to chemical composition. Low, good forging performance), unique aluminum-silicon alloy (which can be strengthened by heat treatment, high mechanical properties, excellent forging performance).
