100KVA Single Phase Submersible Distribution Transformer 4160V To
240V ANSI IEEE Standards
Submersible and occasionally submersible transformers are used
mainly in underground distribution circuits that are susceptible to
corrosive environments and temporary or extended flooding
conditions. Occasionally submersible transformers are built to
operate in an underground chamber or vault subject to potential
flooding under a set of predetermined pressure and time conditions.

Product structure
1.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.
2.The oil tank is made of stainless steel (or high-quality steel
plate multi-layer anti-corrosion technical measures), with a fully
sealed structure and a closed welding structure along the box edge
to minimize the sealing area, and can operate safely for a long
time in the special environment underground.
3.The comprehensive control device of the underground combination
transformer can send communication signals to the outside through
RS485, wired Moden, wireless GSM, or wireless GPRS.
