Wiring is the "blood vessel" of the cold storage electrical system, undertaking the core responsibility of power transmission, and the insulation layer is the key barrier to ensure the safe operation of the wiring. Line aging and insulation layer damage, which may seem like mere line wear issues, will actually cause hidden dangers of short circuits and electric leakage, threaten the safety of personnel and equipment, and at the same time damage the normal operation of the unit, laying operational risks.

          There are various causes of line aging and insulation layer damage, and the hidden dangers are concealed. Long-term use, environmental moisture erosion, temperature changes, and mechanical wear will lead to aging, cracking, and damage of the line insulation layer; loose and oxidized line joints will also accelerate the aging process, expose the line, and then cause electrical hidden dangers such as short circuits and electric leakage.

          Hidden dangers of short circuits and electric leakage will cause multiple hazards. Short circuits are prone to causing electrical fires, burning core components such as contactors and relays, leading to unit shutdown and refrigeration interruption; electric leakage not only wastes electrical energy, but also may endanger the personal safety of operation and maintenance personnel, and at the same time damage the electrical control system, increasing maintenance and operational costs.

          Standard operation and maintenance need to strengthen line protection and inspection: regularly inspect the line status, and timely replace aging and damaged lines and insulation layers; do a good job in line moisture-proof and anti-wear treatment, reinforce loose joints to avoid oxidation; regularly detect line insulation performance, timely check hidden hidden dangers, and eliminate the risks of short circuits and electric leakage.

          Ensuring the integrity of the line and the reliability of the insulation layer is the premise for the safe operation of the cold storage electrical system. Doing a good job in daily inspection and hidden danger investigation, and timely replacing aging and damaged components, can prevent the risks of short circuits and electric leakage, protect the safety of personnel and equipment, maintain the stable operation of the unit, and reduce operational losses.
