Submersible Transformers Underground Vault Installation 25 Kva 13.8KV To 120V 304 SS Oil-Immersed Distribution Transformer
summary
A submersible distribution transformer is an electrical transformer housed in a waterproof metal or plastic enclosure and submerged in water. It is typically designed to supply power when installed in underground vaults, pits, wells, or water-filled chambers.
Product structure
Underground transformers are generally installed in pits constructed with concrete, without occupying surface space. High-voltage casing wells and low-voltage terminals, fuses, plug-in lightning arresters, and pressure relief valves are installed on underground transformers and box covers. These accessories can be observed and operated on the ground.
