The structure of the transparent meter box can be divided into two categories according to the structure: integrated and combined

 
    The integrated transparent meter box is made of a complete mold injection molding process. The integrated meter box has a single-phase meter box, a single-phase left-right structure meter box and a three-phase meter box, so it cannot be divided by phase alone. Integrated or combined.
