Cable tray partition generally refers to the additional partition in the middle of trough cable tray, tray cable tray or ladder cable tray, which is more used than ladder cable tray.
The weight calculation formula of cable bridge clapboard = partition length * partition height * partition thickness * partition density, partition length is generally equal to the length of each bridge, partition height is generally the same as bridge height, partition thickness is generally the same as bridge cover thickness, partition density is the same as bridge material density.
For example, the weight of the 1 meter partition of the galvanized bridge is about 0.71 kg according to the above calculation formula.
The purpose of the cable tray partition is to ensure that the cable signals of different uses in the bridge can be transmitted normally without interference with each other, for example, the weak current cable and the strong power cable are placed in the same bridge, or the power cable and the signal cable are placed in the same bridge, the partition needs to be added in the middle of the bridge.
2, clapboard thickness cable tray diaphragm thickness depends on the thickness of the bridge tray slot, according to the JB/T 10216-2013 bridge standard, it can be the same as or one grade lower than the bridge tray slot thickness, for example, the bridge tray slot thickness is 1.5mm, the bridge tray partition thickness can be 1.5mm or 1.2mm, for example, the bridge tray groove thickness is 1.2mm, the bridge tray partition thickness can be 1.2mm or 1.0mm.
3. Number of clapboards the number of cable tray clapboards is generally 1, and there are also 2 or 3 cases. The more the number is, the larger the width of the corresponding bridge specifications will be.
If there are 2 clapboards, the bridge specification width is generally greater than or equal to 300mm, and if it is 3 clapboards, the bridge specification width is generally greater than or equal to 400mm.
4, clapboard material cable bridge clapboard can be galvanized sheet, but also aluminum alloy or stainless steel, diaphragm is generally metal material, has a strong shielding electronic signal characteristics, plastic material shielding signal difference.
5. There are generally two ways to fix the diaphragm of the cable tray, one is fixed and welded on the bottom tray or transverse brace of the bridge before leaving the factory, and the other is not fixed. During the on-site installation, the diaphragm is fixed together with the tray or transverse brace of the bridge by self-drilling wire, which is more flexible.
