1、尺寸规格不同：电缆桥架比较大(200100 ~ 1200200)，线槽比较小。如果电缆和电线较多，建议使用桥架。

1. Different size specifications: Cable trays are relatively large (200100~1200200), while cable trays are relatively small. If there are many cables and wires, it is recommended to use cable trays.

2、材料厚度不同：金属线槽又叫槽桥，一般是由一整块钢板弯折而成的槽形构件，厚度为0.4-1.5 mm，从概念上来说，它与电缆桥架的区别在于高宽比，托盘较浅较宽，金属线槽具有一定的深度和密封性。然而，电缆桥架比线槽更坚固，线槽用于铺设电缆和电线，通常用于高压系统。

2. Different material thicknesses: Metal cable trays, also known as trough bridges, are generally groove shaped components made by bending a single steel plate, with a thickness of 0.4-1.5 mm. conceptually, the difference between them and cable trays lies in the aspect ratio, with trays being shallower and wider, and metal cable trays having a certain depth and sealing performance. However, cable trays are more sturdy than trunking, which is used for laying cables and wires and is typically used in high-voltage systems.

3、不同填充率：线槽内电线电缆总截面不应超过线槽内截面的20%，载流导体不应超过30根，而桥架内电缆总截面不应超过截面的40%。这是因为安装高度不同。如果安装高度低，必须有盖板。有盖板散热不好，填充率就要小一些。

3. Different filling rates: The total cross-sectional area of wires and cables in cable trays should not exceed 20% of the cross-sectional area in cable trays, the number of current carrying conductors should not exceed 30, and the total cross-sectional area of cables in cable trays should not exceed 40% of the cross-sectional area. This is because the installation height is different. If the installation height is low, there must be a cover plate. If there is a cover plate with poor heat dissipation, the filling rate will be lower.

4、密封性不同：金属线槽密封性好，不需要支架支撑，可敷设在电缆沟和建筑夹层内。槽式桥架有些是半敞开式的，必须用支架支撑。它们一般竖立在室内或室外的空中。

4. Different sealing properties: Metal cable trays have good sealing properties and do not require support brackets. They can be laid in cable trenches and building interlayers. Some trough type cable trays are semi open and must be supported by brackets. They are usually erected in the air indoors or outdoors.

5、不同强度：电缆桥架主要用于敷设电力电缆和控制电缆，线槽强度较低，通常用于敷设电线和通信电缆，比如网络电话等。

5. Different strengths: Cable trays are mainly used for laying power cables and control cables, while cable trays have lower strength and are usually used for laying wires and communication cables, such as network telephones.

6、转弯半径不同：桥架拐弯半径比较大，大部分线槽都是直角转弯。

6. Different turning radii: The turning radius of cable trays is relatively large, and most cable trays turn at right angles.
