network cabinet industry for sheet metal cabinet have new requirements?

3Gnetwork puts forward the requirements of high performance, low comprehensive layout cost, flexible layout and future-oriented evolution for 3G base stations. The outdoor communication cabinet refers to the one that can be directly under the influence of weather, made of metal or non-metal materials, and does not allow operators to enter The operating cabinet can be equipped with communication system equipment, power supply, battery, wiring, temperature control equipment and other supporting equipment inside, which can provide reliable mechanical and environmental protection for the normal operation of the internal equipment, hereinafter referred to as cabinet. The field integrated communication cabinet can be applied to different installation methods such as landing, overhead, hanging poles, etc., and has the characteristics of small size, light weight, and flexible installation, so it can be widely used in DSLAM down-moving points, wireless base stations And other occasions, instead of the traditional computer room. In the wireless network, due to the characteristics of the outdoor integrated communication cabinet, it is an optimal solution to install it on the roof of the building. Generally, two sets of cabinets can be quickly combined into a base station system, including BTScabinet and transmission Power supply integrated cabinet, BTS cabinet mainly handles the installation of BTS equipment and the introduction of feeder lines, while the integrated cabinet will provide supporting functions such as transmission, power supply, battery and wiring.

In the case that the cabinet cannot meet the equipment installation of the large-capacity system, the field integrated communication room has been used in a larger scale because of the characteristics of its parts that can be disassembled, transported, and assembled on site. The installation method of the computer room is usually a floor-standing device, which can be installed on flat ground, on the top of a mountain or on the roof of a building. It is widely used in mobile base stations, broadband access computer rooms, remote module office computer rooms, etc. The field integrated communication room can be divided into two types: integral type and assembled type according to the size and installation and transportation location. The overall field integrated communication room is fully assembled in the factory, which is more suitable for broadband access and remote module room projects. The prefabricated computer room can be applied to any suitable installation site and project because of its feature of installation and construction at the installation site.

In order to ensure the operability of on-site devices and the high quality of the computer room, it is necessary for the panels of Beijing cabinet experts to have high versatility and high interchangeability for the integrated communication room. Sandwich panels are generally suitable for outdoor integrated communication room panels, which are composed of panels and core materials. The panel refers to the outer panel of the equipment room, which can be divided into an outer panel and an inner panel. The core material refers to the sandwich material of the plate in the machine room, which has functions such as heat insulation and increased strength. The front panel materials usually use color-coated boards, FRP glass fiber reinforced plastics, and concrete fiber boards; the core materials usually use materials such as polystyrene, polyurethane, and rock wool. Color-coated plates have excellent corrosion resistance and mechanical strength, but it is more critical to the thickness of the plate and the selection of the brand, and plates of different brand specifications have great performance differences. FRP glass steel plate has excellent corrosion resistance, but its mechanical strength such as bending strength and impact resistance is weaker, and its price is higher than that of color-coated plate. Concrete fiber boards have rough appearance, no core material, poor thermal insulation and mechanical strength, poor water repellency of the boards, and the house is relatively easy to appear pulverized and damp.

The bonding strength between the above plates and the core material is the best with color-coated plates, so it is widely used at present. In the selection of the core material, the polyurethane adopts the high-pressure chemical foaming and high-temperature curing technology of flame-retardant PU material between the inner and outer panels, which avoids the problem of water leakage that may occur during the use of polystyrene boards. High-pressure chemical foaming avoids The occurrence of voids in the core material. The connection between the rock wool and the panel adopts the technology of filling, gluing and pressing, and a closed support keel is installed around it to enhance the strength of the entire panel. However, the disadvantage of the rock wool sandwich panel is that its bulk density is too large and its technical advantages are outstanding. .
