How to prevent static electricity in cable trays
This involves using the correct cable size, avoiding over-bending cables, and ensuring cables are fixed properly to avoid unnecessary movement. Cable trays should also be inspected regularly for signs of wear or damage. Safety of a cable tray is not a matter of compliance with codes, but a matter of saving human life and billions of dollars' worth of infrastructure. This manual will offer practical engineering knowledge. This paper introduces the subject of electrostatic hazards, how they arise and how they can be avoided. Static electricity can cause two main problems in industrial processes. 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. One of the important ways to control electrostatic buildup from static electricity is by properly grounding and bonding equipment and containers.
