Features and construction
The transformer uses a high-grade low-loss core and quality windings to achieve energy-saving performance and stable voltage regulation. The dead-front, tamper-resistant enclosure protects the public and field crews, while the hinged hood provides straightforward access to HV (H1A/H1B) and LV (X1/X2/X3) bushings for connection and servicing.
Typical applications
Residential subdivisions, light commercial and small industrial loads, utility underground distribution, and rural electrification requiring compliant single-phase pad-mount supply.
Customisation options
Capacity, voltage ratio, tap configuration, enclosure color/finish, and bushing/accessory arrangement can be customized to project and utility requirements.
Ordering information
