What is the difference between cable tray and wireway?
Design:
Cable Tray: An open or semi-open structure used to support and organize multiple cables along a route, allowing for ventilation and easy access.
Wireway: An enclosed rectangular channel, often with a removable cover, used to protect and route a smaller number of cables, providing more protection than a cable tray.
Applications:
Cable Tray: Used in industrial and commercial settings where large numbers of cables need to be supported over long distances and easy access is required.
Wireway: Used in applications where cables need more protection from physical damage, often in control rooms or smaller installations.
Accessibility:
Cable Tray: Provides easy access for maintenance and cable modifications.
Wireway: Offers access through removable covers but is more enclosed than a cable tray.
