CT high-voltage cable tray models
CT cable tray systems offer modular, high-voltage-ready ladder and vertical trays with multiple heights, fittings, and CAD models for design and installation.
Overview of CT Cable Tray Systems
CT cable trays are designed for high-voltage and industrial applications, providing mechanical support, strain relief, and safe routing of electrical cables. They are available in various heights and designs, ranging from basic to premium models, and include vertical and horizontal configurations to accommodate complex installations . These trays are typically made from aluminum or steel, offering durability and corrosion resistance, and are engineered to meet UL and NEMA VE-1 standards for electrical grounding and load performance .
Key Features
- Modular Design: CT trays are highly modular, allowing easy assembly and reconfiguration for different project requirements .
- Load Capacity: Trays are load-tested according to NEMA VE-1, including a 1.5 factor of safety, ensuring reliable support for heavy high-voltage cables .
- Vertical and Horizontal Fittings: Vertical fittings allow changes in elevation, while horizontal fittings enable directional changes in the same plane .
- Grounding and Bonding: Many CT trays are UL Classified for use as an equipment grounding conductor, with tested electrical continuity across joints .
- Surface Finishes: Options include powder-coated or galvanized finishes to enhance durability and aesthetics .
Available Heights and Sections
CT cable trays come in multiple side rail heights, commonly including 4", 6", and 7", with straight sections available in various lengths and widths . Covers, splices, and supports are available to secure cables and maintain system integrity.
CAD Models and Design Integration
For engineers and designers, 3D CAD models of CT cable trays are available in formats compatible with SOLIDWORKS, Inventor, Creo, CATIA, Solid Edge, AutoCAD, Revit, and neutral formats like STEP, STL, IGES, DWG, and DXF . These models facilitate accurate planning, simulation, and integration into electrical system layouts.
Compliance and Standards
CT cable trays comply with NFPA 70 (NEC) and NEMA VE-1 standards, ensuring safe electrical performance and suitability for high-voltage installations . Load testing and bonding verification are performed to guarantee mechanical and electrical reliability.
Summary
CT high-voltage cable tray models provide a flexible, modular, and standards-compliant solution for industrial and electrical installations. They include ladder and vertical trays, multiple heights, fittings, and CAD models, making them suitable for both design and field deployment .
