Innovative choice for cabling: caboffi grid Cable Tray

In 1972, Cabo-fi took the lead in launching a metal mesh cable tray in the European market. After more than 30 years of development, Cabo-fi cable trays have been laid more than 150,000 kilometers around the world, it is widely used in various engineering projects. It is not only solid and secure, but also more flexible and simple than traditional bridges. As a result, it is increasingly used in data centers and smart buildings in China.

People sometimes think that the load-bearing capacity of a grid-type bridge is inferior to that of a traditional bridge, especially when it comes to poor grid-type bridges produced by low-end manufacturers. In fact, the load-bearing capacity of truly high-quality grid-type bridges, such as Cabo Fei, is not only comparable to that of traditional closed bridges, but even better than traditional bridges in some aspects. In addition, the open structure of the grid-type cable tray can maximize the ventilation and heat dissipation of the cable. Like in the air, the heat will not gather in the cable tray, so it can save energy and optimize the cable performance. Open structures can also prevent the accumulation of water, dust, debris, bacteria are not easy to breed, more clean, reduce the risk of fire or other security hazards.

All the turns, three links, four links, beam and other special parts on the site by Direct cable tray directly processed into, do not need to go to the factory custom. This not only saves expensive customization costs, but also saves time and projects in advance. At the same time, in recent years, raw material prices have continued to rise, and cost-based consideration of traditional bridge manufacturers have to reduce the thickness of the bridge, but the load-bearing capacity of the bridge is affected. In comparison, high-quality grid bridges are subject to low price constraints and load-bearing capacity is not affected. According to IEC International Electrotechnical Commission) standards, the Cabo-fi mesh cable tray can support heavy-duty armored cables of more than 100 kg per meter, and the bracket spacing is 1.5 meters, the bridge deformation is only 1/200 of the distance.

Grid cable trays are increasingly popular in Europe and North America, because they are suitable for all kinds of cables, not only for the laying of dynamic and control cables, it can also provide excellent support and protection for high-tech and high-bandwidth communication copper and optical cables.

Despite the lack of written evidence, some people believe that in some complex installation environments, especially when many cables are laid in a bridge, the upper-layer cables may cause pressure on the bottom-layer cables, or even damage the performance of the cables. Therefore, they believe that the "flat bottom" cable tray is the most suitable cable management system, although these traditional cable trays are bulky and complex, it is time-consuming to install them.

Since its launch, Cabo-fi mesh cable trays have supported the laying of cat5e and cat6 lines of millions of meters. So far, there has not been a case of cable damage due to installation density. Third-party tests conducted according to TIA/EIA international standards show that the performance of cables in the Cabo-fi Bridge and the "flat bottom" bridge is no different when over five or six cables are laid in a bridge. The temperature test shows that due to the open structure of the grid-Type Bridge, the air is naturally circulated, and the cable can be prevented from overheating, thus optimizing the cable performance.

The unique advantages of metal mesh cable trays make it an ideal choice for laying dynamic cables and data cables. So what happens when the dynamic and electrical cables need to be laid together in a limited space or in some special circumstances? Some projects even need to lay the power cable and data cable in the same bridge. Is this feasible? If feasible, how should the cables go through the cable?

The current standard clearly specifies that the dynamic and data cables must be installed separately. For example, according to European standards, the minimum interval between unshielded dynamic cables and unshielded twisted pair cables is 200; If unshielded twisted pair cables are used, the minimum interval can be 50; if the cable is shielded, the minimum interval is 30mm. The electromagnetic interference of the dynamic cable reduces the performance of the data cable, especially the speed of data transmission.

Placing a steel Separator in a metal tray can greatly reduce the necessary distance between the dynamic cable and the data cable installation. As long as the separator board does not break continuously and has good electrical continuity, even if the dynamic cable and data cable are unshielded, the required interval can be reduced to 50mm. Third-party tests show that the increase of installation spacing can effectively reduce interference. However, the test also found that if the dynamic and electrical cables are laid in a closed bridge at the same time, the interference intensity is greatly increased. Therefore, the Use of Open Grid-type bridges with low-resistance connectors and metal separation boards can not only reduce the risk of electric shock, but also save space and raw materials, reduce installation costs.
