DuPont™ ReliatraN™

Solid Insulation Distribution Transformer (SIDT)

DuPont™ ReliatraN™ SIDT transformers represent a major advancement in transformer safety, and reliability. ReliatraN™ SIDT transformers are oil-free, which represents a breakthrough in technology for Utility distribution transformers used to power homes in residential communities. With a durable, maintenance- free exterior polymer shell, ReliatraN™ SIDT transformers are designed for sub-surface installations. As a result, high and low voltage connections are inaccessible to the public.

Improved SIDT reliability features include: longer short circuit withstand time, which exceeds applicable industry standards and have been proven by testing; the use of Nomex® paper for extending critical insulation life; and the use of 100 percent solid dielectrics which can’t leak and therefore diminish service life.

Built to deliver exceptional mechanical strength, and resistant to moisture and corrosion, DuPont™ ReliatraN™ SIDT transformers are well suited for use in a variety of applications, including:

  • Residential, commercial, and urban underground distribution
  • Indoor protected commercial structures
  • Corrosive environments
  • Damp or humid areas
  • Waterfront locations
  • Industrial facilities
  • Areas prone to storms and flooding
