What are the requirements for punching holes in cable trays
The minimum setup for basic cable tray production includes a leveler or manual decoiler, a punch press or laser cutting system for holes, a roll forming machine or press brake for shaping, and a shearing machine for cutting to length. Cable trays are produced either as individual sections (typically 2–3 meters long) or as part of an automated production line. Cable trays play a vital role in supporting electrical cables and wires in commercial, industrial, and utility installations. For proper installation, design, and maintenance, adherence to international standards is essential. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when the cable tray cont d for instrumentation and control applications that require.
