Parameters of cable tray tees
Cable tray tees are available in equal and unequal configurations, with widths ranging from 50mm to 900mm, made from mild steel, stainless steel, or aluminum, and finished in pre-galvanized, hot-dip galvanized, or stainless steel grades.Types of Cable Tray TeesCable tray tees are designed to branch a main cable tray run into two directions. The main types include:Equal Tees: Both branch arms have the same width as the main run.Unequal Tees: Branch arms have different widths, allowing for varied cable distribution.Crossovers: Used to intersect two cable tray runs at right angles .Materials and FinishesMild Steel: Standard material, available pre-galvanized (PG) or hot-dip galvanized (HDG) for corrosion resistance.Stainless Steel: Grade 1.4404 (316L) for high corrosion resistance, suitable for harsh environments.Aluminum: Lightweight and corrosion-resistant, often used in industrial or outdoor applications .DimensionsWidth Range: 50mm to 900mm, accommodating light, medium, and heavy-duty cable tray systems.Depth/Height: Typically matched to the main tray section to maintain structural integrity and cable fill compliance.Length: Standard tee lengths are designed to fit seamlessly with straight tray sections, often modular for field assembly .Standards and ComplianceCable tray tees are manufactured to comply with international standards such as EN 61537-2007, NEMA VE 1, and NFPA 70. These standards ensure:Proper load-bearing capacity.Compatibility with straight tray sections.Adequate ventilation for heat dissipation.Safe installation and maintenance .Installation ConsiderationsTees can be fitted with closed or ventilated covers to protect cables.Part numbers are often generated based on depth, width of main and branch runs, and finish (e.g., CTUT 25/0300/0150/PG for a pre-galvanized tee with specified dimensions), .Correct sizing should consider cable fill, NEC compliance, and structural load to prevent overcrowding and heat buildup .SummaryCable tray tees provide flexible branching solutions in cable management systems. Selecting the correct type, material, finish, and dimensions ensures compliance with standards, structural integrity, and efficient cable routing. Equal and unequal tees, along with crossovers, cover a wide range of industrial, commercial, and data center applications, supporting widths from 50mm to 900mm and multiple material options for durability and corrosion resistance .
