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. The result is 13-21% lower operat-
ing losses than conventional 150°C rise units. 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 defi nitely mean higher reliability.
The extra benefi t is being able to operate either of these
overload capacity of 15-30% without compromising normal
life expectancy (See Figure 2).
Low temperature rise transformers are designed for any criti-
cal application requiring extra overload capability,
lower than average total losses and/or cooler operating
temperatures. All are available with either a 115°C or 80°C
thermal rise and a Class 220°C insulation system.
