Winley Electric supplies single-phase 167kVA pad-mounted distribution transformers built with 304L stainless steel tanks and enclosures for harsh, corrosive outdoor environments. Standard mild steel pad-mount enclosures often suffer early rust and surface breakdown when exposed to salt spray, severe moisture, or chemical atmosphere.
This unit combines a full 304L stainless steel housing with copper windings, 12470GrdY/7200V dead-front HV connection, 240/480V LV distribution, and bayonet expulsion fusing to ensure safe, stable power delivery in demanding outdoor installations.
