Tape wound cut cores are ideal for transformer design engineers who require one to several thousand transformers in shapes that are unavailable in standard lamination sizes. They also are ideally suited where weight or dimensional requirements are critical and have to be reduced, including chokes, pulse applications and current transformers.

Transformers used for the distribution and control of electrical energy consist of a primary and secondary copper wound coil carrying a magnetizing current surrounding an iron core which is used for the transferring of power from the primary to the secondary coil. The iron core is normally made of thin gauge laminated steel either of low cost stamped laminations in the assembly form of EI`s or EE`s (see Figure 1) or similar laid up structures sometimes in a more costly tape wound double cut core assembly as shown in Figure 2.
