10 Series 76 - Large capacity encapsulated transformers Series 76 Three Phase Isolation Transformers offer all the advantages of encapsulated transformers - in larger kv sizes. These transformers are particularly well suited to harsher environments where airborne contaminants may adversely effect ventilated, dry type transformers. vailable in 600 and volt primaries, these transformers feature a 115 temperature rise, 200 insulation system, electrostatic shields, and copper windings. The core and coil are completely epoxysilica encapsulated for protection against environmental contaminates. Transformers in this series are available in additional voltage combinations and NEM Type 4, stainless steel enclosures for petrochemical or marine applications. onsult your Dongan Representative or the factory for price and delivery. Features NEM Type 3R, indoor / outdoor enclosure. opper wound, 115 temperature rise. Epoxy-silica encapsulated construction. Featuring three phase 600 or volt Delta primary windings with a secondary winding of 208Y/120. Special order options include stainless steel enclosures. kv ap. 600 D D 208Y/ Y/120 atalog No. atalog No. Hz. s 600 D D 208Y/120 Wall Mount (WM) Floor Mount (FM) (lbs) SH SH WM SH SH FM SH SH FM SH SH FM SH* SH FM *75 kv is not UL Listed. 15 kv Wall Mount - Encapsulated - NEM Type 3R Wiring Diagram - 76 Series kv Floor Mount - Encapsulated - NEM Type 3R 34 Dongan Electric Manufacturing ompany
