GNEE Steel pad mounted transformers
The 75kVA transformer is in radial feed configuration. For high voltage it uses split insulating bushings (H1, H2, H3), while for low voltage it uses 4-hole spade terminals (X0, X1, X2, X3). The transformer is equipped with a liquid level indicator and an oil temperature indicator. Each indicator has an alarm contact for remote monitoring when the oil level or temperature is abnormal. Additionally, it is equipped with a two-position load disconnect switch. Upon customer request, this 75 kVA pad-mounted transformer can be supplied without fuse protection. With options such as bayonet fuses (with iso link) and current limiting fuses, the GNEE Transformer offers the flexibility to meet your specific requirements.

The 75 kVA single-phase pad-mounted transformer employs the ONAN cooling method and uses mineral oil as the insulating liquid, characterized by a fire point equal to or less than 300°C. Polarity is additive for the 75 kVA transformer, and the core is effectively grounded. These 75 kVA transformers feature two internally connected high-voltage bushing wells, identified as H1A and H1B, fitted with removable bolts. These wells can be connected to the distribution system via deadbreak elbows, designed for dead-front operation, and strictly adhere to the dimensional and electrical requirements outlined in IEEE 386. Each high-voltage bushing well is thoughtfully furnished with a protective cap. The low-voltage bushings are equipped with three stud-type bushings with copper plating and 7-hole terminals. Every unit 75 kVA transformer is equipped with two 2-position oil-immersed load-break switches, specially designed to operate within a temperature range spanning from -40°C to 120°C, employing a hot-stick mechanism.
