Cooper Power Systems has released its PEAK transformers, which the company says are uniquely designed to manage increased loads and temporary overload capacity with a four-times-greater life expectancy when compared to mineral-oil-filled transformer alternatives.
Utilizing an advanced high-temperature insulation system - composed of thermally upgraded kraft paper, an optimized core and coil design, and Envirotemp FR3 dielectric fluid - a 75-degree average winding rise (AWR) PEAK transformer results in a smaller footprint and lighter unit capable of the same ratings as a physically larger 65 AWR-rated unit, the company says.
PEAK transformers are filled with a biodegradable alternative to transformer oil, Envirotemp FR3 dielectric fluid, which Cooper says extends transformer life and raises fire-ignition resistance. In addition, this soybean-oil-based fluid creates a barrier against water at the surface of the insulation, making the thermal kraft paper in the coil windings stronger and longer lasting.
PEAK transformers are available in 75 AWR, 55/75 AWR and 65/75 AWR in both 5-167 kVA single-phase pole-mount transformers and 5-167 kVA single-phase pad-mount transformers in either ANSI 1 or ANSI 2 configurations.
