  • Bending radius of high voltage cable trays

    Bending radius of high voltage cable trays

    Click "Calculate" to see the minimum bending radius and the recommended standard tray bend radius (300mm to 900mm) required for safe installation. Tray bend radius must be ≥ minimum cable bend radius. Use the largest cable diameter in the tray for calculation. When bent too sharply, helical metal tapes can eparate. When installing high-voltage cables, maintaining the correct bending radius is critical. Improper bending can damage insulation, weaken the conductor, and reduce the cable's life span.
