Pad Mount Transformers for Utility
Pad-Mount Transformers for Utility
Pad-mount transformers for the utility market are ground-mounted on a concrete pad and are distribution transformers that service underground power networks. The transformers step down the distribution voltage to the secondary voltage for residential, commercial, and industrial loads. The fully enclosed, compact, low sound, weatherproof construction, and tamper-proof features make these transformers a preferred choice for installation in public areas. These transformers are available in single phase three-phase and grounding (Zig Zag) configurations. Primary drivers for growth in Pad Mount Transformers for the utility market include:
- Expansion of rural and urban residential communities.
- Growing investment in upgrade of aging utility infrastructure and transmission & distribution networks.
- Need for safe, low sound, compact, reliable distribution transformers in public access areas.
- High efficiency, DOE guidelines.
- Growth in digital infrastructure with harmonic loading.
