Does HPS build primary unit substation transformers?

Primary Unit Substation Transformers are located outside and typically range from 750 kVA to 10,000 kVA three-phase. The Primary voltage ranges from 2400 VAC to over 100,000 VAC and the secondary from 2400 VAC to 34,500 VAC. Taps are typically manually changed while the unit is de-energized. The primary connections are typically delta using bushings, throats or air terminal chambers.

While often oil, HPS dry-type transformers can offer similar performance with a lighter weight and fewer environmental concerns.
