LOW TEMPERATURE RISE

SolaHD low temperature rise transformers feature a 220°C insulation system and temperature rise of only 80°C or 115°C

under full nameplate load. Reduction in temperature rise increases reliability.

The 35°C thermal reserve on 115°C rise units and 70°C reserve on 80°C rise units definitely mean higher reliability. The extra benefit is being able to operate either of these transformers as a 150°C rise unit and have a short term overload capacity of 15-30% without compromising normal life expectancy (See Figure 1 below).

Low temperature rise transformers are designed for any critical application requiring extra overload capability and cooler operating temperatures.

All are available with either a 115°C or 80°C thermal rise and a Class 220°C

insulation system.
