槽式电缆桥架和托盘式桥架就是底部不同，有孔和没孔。槽式的不利于散热，托盘散热稍好。

Trough cable trays and tray trays have different bottoms, with or without holes. Slot style is not conducive to heat dissipation, while tray style has slightly better heat dissipation.

槽式桥架是封闭的；托盘式桥架是桥架底部有很多腰形孔，以利于散热；梯式桥架的底部像楼梯一样，侧面有挡板，灰尘多的地方用梯式的，不会积灰。

The trough bridge is enclosed; Tray type bridge has many waist shaped holes at the bottom of the bridge to facilitate heat dissipation; The bottom of the ladder style bridge is like a staircase, with side shields. Ladder style bridges are used in dusty areas to prevent dust accumulation.

槽式桥架也叫槽式电缆桥架，是一种全封闭型电缆桥架，它很适用于敷设计算机电缆、通信电缆、热电偶电缆及其它高灵敏系统的控制电缆等，它对控制电缆屏蔽干扰和重腐蚀环境中电缆的防护都有较好效果。

Trough type cable tray, also known as trough type cable tray, is a fully enclosed cable tray that is suitable for laying computer cables, communication cables, thermocouple cables, and other control cables for high-sensitivity systems. It has good effects on shielding interference and protecting cables in heavily corrosive environments.

槽式电缆桥架主要用于敷设截面小但数量多的电线电缆。托盘式缆桥架主要用于敷设截面大数量较少的电力电缆。

Trough type cable trays are mainly used for laying wires and cables with small cross-sections but large quantities. Tray type cable trays are mainly used for laying power cables with large cross-sections and small quantities.

槽式桥架很适用于敷设计算机电缆、通信电缆、热电偶电缆及其槽式桥架高灵敏系统的控制电缆等。

Trough type cable trays are very suitable for laying computer cables, communication cables, thermocouple cables, and control cables for highly sensitive systems in trough type cable trays.

托盘式桥架适用范围托盘式电缆桥架是石油、化工、轻工、电视、电讯等方面应用很广泛的一种。

Tray type cable tray is widely used in petroleum, chemical, light industry, television, telecommunications and other fields.

槽式桥架一般仪表用的多，电气桥架一般多用梯式桥架和托盘式桥架。其中动力电缆一般只用梯架式桥架。托盘式桥架一般用于控制电缆的敷设。主要是依据电缆散热性能。

Slot type cable trays are commonly used for instruments, while ladder type and tray type cable trays are commonly used for electrical cable trays. Among them, power cables generally only use ladder type cable trays. Tray type cable trays are generally used to control the laying of cables. Mainly based on the heat dissipation performance of the cable.
