What will affect the sealing effect of small power distribution units with lights?

The sealing effect of small power distribution units with lights will be affected by various factors, mainly including the following aspects:

Material and condition of sealing ring: The sealing ring is a key component of the sealing performance of the small power distribution unit. Its material determines its resistance to chemicals, high temperature resistance, oxidation resistance, and corrosion resistance. During long-term use, the sealing ring may lose its elasticity due to aging, hardening, or corrosion by chemical substances, resulting in a decrease in sealing performance.

Installation and fastening: The fixed position and degree of compression of the sealing ring directly affect the sealing effect. If installed improperly or if the compression nut is loose, it can lead to poor sealing, allowing external substances such as dust and moisture to enter the interior of the small power distribution unit.

Environmental factors: The environment in which the small power distribution unit is located also has a significant impact on its sealing effect. For example, high temperature environments can accelerate the aging of sealing rings, while corrosive environments may directly damage sealing materials. In addition, environments with high humidity may also cause seals to become damp and expand, affecting their sealing performance.

Operation and maintenance: Regular maintenance and inspection are crucial for maintaining the sealing performance of the small power distribution unit. Neglecting maintenance may result in damage or loosening of seals, thereby reducing the sealing effect.

In summary, to ensure that small power distribution units with lights have good sealing effects, it is necessary to select high-quality sealing materials, correctly install and tighten sealing rings, pay attention to environmental factors, and conduct regular maintenance inspections.
