Product Introduction
In operating power transmission and transformation equipment, such as switchgear cabinets, pad-mounted transformers, control cubicles, ring main units (RMUs), and outdoor terminal boxes, the compact insulation distances between components make them highly susceptible to electrical discharge, flashover, circuit breaker tripping, and even equipment burnout when exposed to moisture condensation. Currently, China's power sector widely employs heating and ventilation methods to prevent condensation in switchgear, motor control centers (MCCs), and terminal boxes. While these conventional approaches provide some degree of moisture protection for high-voltage equipment, they demonstrate limited effectiveness in fully dehumidifying sealed cabinets under high-humidity conditions.
