All Acme Drive Isolation Transformers (DITs) above 7.5kVA are wound with strip windings to ensure the lowest possible eddy current losses. All our DITs use a three leg wound core. THis superior design has very low losses and quiet operation. Both of these features combine to signicantly reduce losses and operation costs compared to other types of constructions.
All Acme DITs up to and including the 220kVA have copper terminations. The transition from aluminum strip coil conductors to copper terminations is accomplished by a bonding process known as "Koldwelding™" This process has been used by Acme for over 25 years to provide a trouble-free, permanent bonding of the two metals.
