The stability of cold storage operation depends on stable power supply. Insufficient power cable diameter, unstable voltage and phase loss are the three core hidden dangers affecting the normal operation of the unit, which are directly related to equipment service life and refrigeration effect.

         Insufficient power cable diameter will block current transmission, increase line loss, not only reduce power supply efficiency, but also accelerate line aging, increasing the risk of short circuit and overheating, and affecting the normal start-up of equipment. Unstable voltage will lead to abnormal operation of the unit, insufficient cooling capacity, and at the same time accelerate the wear of core components, shortening the service life of the equipment.

         Phase loss operation will cause uneven force on the motor, resulting in abnormal noise and overheating. In severe cases, it will burn out the motor, cause the unit to shut down, and increase maintenance costs. It is necessary to strictly control the selection of power cable diameter, standardize voltage management, check phase abnormalities in time, eliminate hidden dangers, and ensure the stable and efficient operation of the cold storage unit.
