Product Description

2019 Hot three-phase oil immersed fully sealed distribution transformer

 

S13 (11)-M-30~2500kVA three-phase oil immersed fully sealed distribution transformer is different from the general oil immersed transformer. It cancels the oil storage tank and uses the corrugated plate heat sink of the oil storage tank to radiating & cooling, which to compensate the increase or decrease of oil volume by its elastic expansion and contraction.
