Imagine a 90° ladder bend, the radius is the distance from where your cables enter the arc of the bend to where they leave it. In EPC and industrial automation projects, a tray that is undersized forces last-minute redesigns, cable overcrowding, poor heat dissipation, and messy site rework. A smaller radius size might mean that a fitting will support your cables over a 90° angle for example over a short distance, whereas a larger radius can result in more of a. When installing copper conductors or cables around curved surfaces, through conduits, or within cable trays, it is important to respect minimum bending radius requirements. Excessive bending can damage insulation, deform conductors, compromise shielding effectiveness, and reduce the long-term. 3 (2" CABLE FILL) F = POLYESTER 06 = 6" 90 = 90 DEG.
