Cable tray is a modern cable, fiber optic supporting equipment, the beginning of the technology and talent from foreign bows l into, after many years of development, and slowly in all walks of life in our country is widely used, it is mainly used for cables, cables and optical fiber support and protection role. Therefore, the purchase of cable tray is crucial, directly related to the cable can operate normally. So we should be in the purchase of cable tray when how to choose?
1、Choose by looking at the material
Currently on the market cable tray has a lot of materials, such as carbon steel, stainless steel, aluminum alloy, plastic, color steel, etc., each material has its own characteristics, we must pay attention to when choosing the geographic area and the characteristics of the cable operating environment, the application of the application of the bridge scene to be considered.
For example, in China's coastal cities, due to the humid air, in the equipment wiring should be considered when the cable tray corrosion resistance and durability. Underground parking lot, for fire prevention requirements are particularly high, you can use fireproof cable tray; and machine room heavy ground, the requirements of the cable tray is even higher, need to take into account the cable interference as well as load-bearing. There are many examples will not be cited to say, in short, there are a lot of cable tray material, we are buying, we must be tailored to local conditions, according to the actual needs to choose.
2、Look at the craftsmanship of the bridge
With the bridge material, the production of bridge I art is also a variety of bridge electro-galvanized, hot-dip galvanized, plastic spraying and other processes. Electro-galvanized bridge refers to the use of electrolytic principles, and then in the bridge on the surface of a layer of zinc, so that the purpose is to prevent the role of corrosion; galvanized channel bridge and galvanized grid bridge is the use of power is relatively large products; in order to fire prevention, the general use of plastic spraying, the production of the bridge will be sprayed on the surface of the bridge with fire-resistant coatings, so that the purpose is to make the bridge has fire-resistant properties.
3、Choose a competent factory
Currently in the domestic production qualification of about 300 companies, we must be screened in the selection of manufacturers, the main consideration of two factors, one is the cost, and the second is to choose the right manufacturer, customized production. Jinlai electric have factory certificates, product quality in line with standards.
4、About Logistics
The production cycle of the bridge is about 5 to 7 days, in advance to communicate with the manufacturer, choose the right manufacturer, so as to ensure that the production and delivery on time. Jinlai electric cable bridge conventional specifications are available in large quantities in stock, so the delivery is faster, logistics and distribution.
