What is the impact of humidity on the life and performance of power cords

Humidity is one of the important environmental factors for the service life and performance of power cords. In electrical systems, the insulation material of power cords plays a vital role, and humidity directly affects the performance of insulation materials, thereby affecting the reliability and safety of the entire power cord.

In terms of insulation performance, high humidity will cause the insulation material to absorb water and reduce the insulation performance. Once the insulation performance decreases, the power cord is prone to leakage or short circuit, increasing the safety risk of the electrical system. Therefore, in a high humidity environment, be sure to select insulation materials with good waterproof and moisture-proof properties to ensure the insulation performance of the power cord and the safety of the system.

In terms of wire conductivity, high humidity will cause water vapor to accumulate on the surface of the power cord, increase resistance, and reduce conductivity. The decrease in conductivity may lead to poor current transmission and affect the operating efficiency of the entire electrical system. Therefore, in an environment with high humidity, a power cord with good conductivity must be selected to ensure the normal operation of the system.

In terms of corrosion of metal parts, high humidity will accelerate the corrosion of metal parts, causing rust on connectors, plugs and other parts, affecting the connection performance and transmission efficiency of the power cord. Therefore, when using power cords in a high humidity environment, corrosion-resistant metal parts must be selected, and regular inspections and maintenance must be carried out to extend the service life of the power cord.

In terms of insulation material aging, the insulation material of power cords that are in a high humidity environment for a long time is easily corroded by moisture, resulting in aging and degradation. After the insulation material ages, the insulation performance of the power cord is significantly reduced, and it is easy to have safety hazards such as leakage and short circuit. Therefore, when using power cords in a high humidity environment, regular inspection and maintenance are required, and aging insulation materials must be replaced in time to ensure the reliability and safety of the power cord.
