Factors that affect the sealing performance of the meter box and SPDU include:

Material selection: The selection of meter box and SPDU materials is directly related to the sealing performance. Choosing high-quality, weather-resistant materials, such as rubber seals or silicone seals, can help improve the seal.

Manufacturing process: The accuracy and quality of the manufacturing process are directly related to the fit of the sealing components. High-precision manufacturing processes ensure that gaps between sealing components are minimized, improving sealing performance.

Design structure: The design structure of the meter box and SPDU should take into account various external environmental conditions, such as waterproofing, dustproof, etc. Reasonable design structure can enhance sealing performance.

Installation process: Whether the installation process is carried out in strict accordance with the regulations, especially the correct installation of the sealing components, is directly related to the quality of the sealing performance.

Environmental factors: External environmental conditions, such as temperature, humidity, ultraviolet rays, etc., may affect the performance of the sealing material, thereby affecting the sealing of the meter box and SPDU.

Regular inspection and maintenance of sealing components and timely replacement of aging sealing materials can effectively improve the sealing performance of the meter box and SPDU, ensure its normal operation and extend its service life.
