Perforated Cable Tray is a fully enclosed cable tray, suitable for laying computer cables, communication cables, thermocouple cables and other control cables of highly sensitive systems. It has a good effect on shielding interference of control cables and protecting cables in heavy corrosion environments. It is widely used in places that need to shield electrical interference and protect against heavy corrosion environments, such as chemical plants, coastal areas, high-rise buildings, subway tunnels, etc. Its fully enclosed design can effectively prevent dust and moisture from entering, ensuring the safe operation of cables.
