Outdoor cabinets are used to protect communication, power, and industrial control equipment in outdoor environments, providing structural protection, environmental sealing, and security management. These cabinets typically need to be dustproof, waterproof, corrosion-resistant, UV-resistant, temperature-resistant, and weather-resistant.

Outdoor cabinet reliability is defined not only by the enclosure itself, but also by the quality and compatibility of its components. Key parts—such as gaskets, locks, fan-filter systems, cable glands, drainage and anti-condensation designs, grounding and surge protection—directly affect ingress protection, thermal performance, and maintenance frequency.

Outdoor electrical equipment is susceptible to heat buildup inside the enclosure during summer months due to high temperatures and direct sunlight. This can lead to excessive temperature rise in components, performance degradation, and frequent activation of protective devices, affecting power supply stability and equipment lifespan.
