Professional Cable Tray Manufacturer

Some people may not know much about the cable tray, but it is actually a necessary facility to protect the cable in the project, which is mainly used to set up the cable for unified classification to avoid clutter and damage. 
Do you know what kinds of cable trays are divided into? 
What are the basic uses of cable tray vendors? 
Let's follow the staff of Hongfeng Cable Bridge Co., Ltd. to learn about it. 
Types and basic uses of cable trays: cable trays are suitable for power cables with a voltage below 10 kV, as well as indoor and outdoor overhead cable ditches and tunnels for control cables, lighting wiring, etc. 
Cable tray has the advantages of full variety, wide application, high strength, light structure, low cost, simple construction, flexible wiring, installation standard, beautiful appearance, convenient maintenance and so on. 
1.Combination type
1.According to the form (1) trough type (2) pallet type (3) cascade type
2. According to surface treatment,
(1) cold-dip galvanizing and zinc-nickel alloy (2) plastic spraying (3) painting (4) hot-dip galvanizing( 5) hot-dip galvanizing indoor use ambient temperature not more than 1000 meters   ambient temperature-25 ℃ ~ 45 ℃ 3, cable tray implementation standard: 1. JB/T10216-2000 "electronically controlled distribution cable tray"
2.Enterprise standard: Q/321182AEG001-1997 3. QB/T1453-92 cable tray 4. JB/T6743-93 indoor and outdoor steel cable tray anticorrosion environmental technical requirements 5. DB32/144-1996 cable fireproof slot conforms to the standard scope of application: cable tray for industrial and civil buildings indoor and outdoor, high and low voltage power transmission and distribution projects. 
4. Technical conditions:
(1)Normal use condition
(1)the altitude of the installation site shall not exceed 2000 meters. 
(2)the parameters of different climatic environment grades are selected according to temperature, humidity, fire prevention and so on. 
2.Special use conditions
(1)laid in different chemical corrosion environments: salt fog, hydrogen sulfide, hydrogen chloride and so on. 
(2)laid in the fire line. 
(3)laid above 2000 meters above sea level. 
3.Structural requirements of cable tray
(1)Protection grade: no hole tray (trough type) indoor not lower than IP30 outdoor not lower than IP33 (2) protection grade: fire bridge tray indoor not lower than IP40 outdoor not lower than IP44 material should meet its own relevant standards. 
Cold rolled steel plate GB/T700-1988GB/T11253 aluminum GB/T3880 and GB/6892 FRP GB/T15568 refractory bridge should be used for steel production. 
Grade B in GB8624-1997. 
(3)Common specifications: high 40 50 60 80100 150 200 wide 60 80100 150 200 250 300 400 500 600 800. 
1000 1200 . 
(4)Plate thickness minimum plate thickness of steel bridge: width B allows minimum plate thickness & B1 < 00 1.0 100 < B < 150. 
1.2,150 ≤ B < 400,1.5,400 ≤ B ≤ 800,2.0,800 < B < 1000, 2.51000 < B < 1200, 3.0. 
The thickness of the connecting plate can be selected at least according to the same thickness of the bridge or a grade of cover plate can be selected according to the thickness of the bridge. 
(5)length of straight through: Lang 2000 Lang 3000 Lang 4000 Lang 6000 Lang 8000 is the types and basic uses of cable tray vendors briefly explained by the staff of Hongfeng Cable Bridge Co., Ltd. Different kinds of cable trays have different uses and different areas, for example, the cable trays used in some underground parking lots or underground garages are required to be moistureproof and so on. 
Otherwise, the general bridge will be more easily damaged in the relatively dark and humid environment of the underground garage. 
I hope our introduction will be helpful to you.
