Maintenance is simple: the design should be as simple as possible to facilitate daily maintenance and repair. Therefore, the design of the reel drum heat insulation device needs to balance the heat insulation performance, mechanical strength and maintenance simplicity to meet the application requirements of high torque and high radial support force.
