Types of cable trays tees

Cable tray tees are branch fittings that connect three tray sections, available in equal, unequal, and specialized configurations for efficient cable routing.

Overview of Cable Tray Tees

A cable tray tee is a fitting that allows a main cable tray run to branch into one or more secondary routes while maintaining continuous cable support. Unlike bends, which only change direction, tees create a branch pathway, simplifying installation and improving long-term reliability in electrical and communication systems .

Common Types of Cable Tray Tees

1. Equal Tee
   • All three branches of the tee have the same width.
   • Ideal for situations where the main and branch runs carry similar cable loads.
   • Commonly used in data centers, commercial electrical systems, and manufacturing areas .
2. Unequal Tee
   • The branch width differs from the main run.
   • Useful when the branch carries fewer cables or lighter loads.
   • Helps optimize material usage and maintain proper cable support .
3. Horizontal Tee
   • All three tray sections remain on the same elevation.
   • Simplifies installation and provides easy access for maintenance.
   • Suitable for branching into equipment rooms or row distribution in commercial setups .
4. Vertical Tee (Rising Branch)
   • The branch rises above the main tray route.
   • Used when cables need to reach higher equipment or different floor levels.
   • Ensures continuous support while changing elevation .

Material and Finish Options

Cable tray tees are available in various materials to suit environmental and load requirements:

• Mild steel (pre-galvanized or hot-dip galvanized)
• Stainless steel (grade 1.4404 / 316L)
• Covers can be closed or ventilated depending on cable protection needs .

Applications and Advantages

• Efficiently distribute power and communication cables from a central source.
• Reduce onsite modifications and labor.
• Maintain proper cable support and organization.
• Facilitate future expansion and maintenance . Selecting the correct type of tee depends on cable load, tray width, elevation changes, and environmental conditions, ensuring a safe, organized, and durable cable management system.
