An Experiment with Heat Insulation Materials to Achieve Optimal Temperature Reduction Performance

The study addresses the critical issue of wire overheating and burning in cable trays, which compromises the safety and reliability of the system. Through a series of controlled experiments. Various insulating materials are used to achieve the required targeted temperature. The insulation materials like glass wool, ceramic board and aluminum (reflective insulator), mica sheet and their combination have been experimented through the simulation and physical trials. For experiments we used as it is scaled setup of actual machine arrangement. This experimental setup includes Drum, coil inside drum, cable tray placed in front of drum, Heat sleeve inside cable tray and temperature sensors which is placed inside drum, outside drum, inside cable tray, from inside of the insulation which is inside from casing, and from the outside of the casing. For the experimentation we assumed condition that constant temperature inside the drum and then test over numerous different types of insulations and their combinations. The results indicate significant improvement in temperature management, reducing the risk of wire failure and enhancing overall durability of wires. The insulation materials considerably enhance the performance of thermal management. Comparing it to an uninsulated condition, the usage of ceramic boards together with aluminum reflective insulators reduced the temperature at the cable tray level by as much as 45%. Glass wool and mica sheet effect up to 30-35% and feasibility in flexible usage areas. The internal temperature within the cable tray is represented by sensors, which also suggest the effectiveness of insulation materials for safety in operation. From the experimental findings, it is evident that insulation materials play a role in restricting the heat transfer to the cable tray and, consequently, protects the integrity of a wire. Ceramic board and aluminum reflective insulators came on top among materials tested in terms of thermal resistivity and overall performance. Glass wool and mica sheet are also equally promising even under less demanding conditions. These results provide a solution for achieving practical thermal management techniques in RECD systems and other similar areas of hightemperature applications, improving durability and reliability of wires while ensuring system safety.
