Things to keep in mind when using a cable tray system

Introduction

Cable trays are very popular cable management systems used in the industry that provides additional protection to cables from physical damage. Cable tray manufacturers offer a wide array of cable tray systems ranging from solid-bottom trays, ladder cable trays to wire mesh cable tray designs. These are effective systems that protect wires and prevent damage from moisture, dust, dirt, and other chemicals. The equipment also prevents fire shock, overheating, and other problems. It is by far the best solution for managing cables provided they are installed well, inspected in a timely manner, and most importantly bought from a reputed Cable Tray Manufacturers in India. That said, given below are common things to consider when businesses install, use and maintain cable tray systems in the industry.

 

Things to keep in mind when using Cable tray

Avoid overloading cable trays- A common mistake that most people often commit when using a cable tray system is overload the equipment with cables beyond their capacity. When cable trays carry wires that are delivering electrical power, there’s a possibility of short circuits and fire, or maybe arc flash. Overloading of cables in the cable tray may make things worse. Overloading may suppress the airflow, resulting in disruptions and premature system failures. Moreover, coatings or insulation could provide toxic fumes if they burn. In most cases, cable trays should not be filled beyond 40 or 50 percent of their physical capacity or weight. In addition, cable trays must be properly grounded and tested before any wire or cables are energized.

Using suitable materials for insulation-

Selecting a suitable material for cable trays is crucial to ensure its long-lasting. So, for instance, certain materials, like flexible cords, could also be inappropriate as the insulation it offers makes it brittle over time, and increases the possibility of fires and electrical shorts.

Removal of unused cables-

Make sure the cable tray has only enough cables placed in it based on its capacity. Further, extra cables that are often not used should be removed from the trays to ensure the trays comply with the code and capacity requirement.  Often, several cables are abandoned when systems are upgraded. So, regular inspection is necessary to ensure the removal of such cables from systems. At all times, it is best to maintain cable trays with only 25-50 percent capacity as it leaves enough space for additions of wires or cables in the future and does not create any safety hazards for the structure.

Suitable to the environment-

It is important that businesses or industries consider this parameter when installing, using, and maintaining cable tray systems. Not only should the cable tray be suitable for the environment in which they are installed but it must also ensure that the cables inside them too can handle the environment. It is advisable to use cable tray systems that are ideal for extreme temperature conditions like high, or low temperature, resistance to moisture chemicals, or other such challenges.
