Wire and cable CT

CT refers to trough-type cable tray, which is also called trough-type cable tray. It is a fully enclosed cable tray. It is most suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has good effects on shielding interference of control cables and protection of cables in heavy corrosion environment.

Difference between cable tray ct and galvanized trunking mr

1. Cable tray is used to lay power cables and control cables; 2. Galvanized trunking is used for laying wires and communication cables; 3. The cable tray is relatively large (200x100 to 600x200), and it is used more between floors and distribution rooms in general buildings; 4. The galvanized trunking is relatively small, the turning radius of cable tray is relatively large, and most of the galvanized trunking turns at right angles; 5. The span of cable tray is relatively large, the galvanized trunking is relatively small, and the fixing and installation methods are different; In some places; 6. The cable tray is not covered, and the galvanized trunking is almost sealed with cover Galvanized trunking is widely used in distribution cabinets and instrument cabinets; 7. Galvanized trunking is used for cable routing, and cable tray is used for cable routing.
