Installation Dimensions Diagram
Note:
¤ This product consists of an underground transformer,lightbox-style outboor HV/LV switchgear, and a prefabricated underground pit.
¤ The lightbox-style switchgear features a dual-door design, ensuring the HV/LV equipment remains protected by an independent enclosure even if the lightbox is damaged.
¤ The prefabricated pit adopts a fully sealed waterproof design, with decorative tiles on the cover and a lockable maintenance hatch.
¤ The transformer uses plug-and-play three-phase cable connections on both HV/LV sides, with IP68-rated sealing for prolonged underwater operation.
