Calendared - Transformer board TI
Applications of transformer boards TI are curved components like cylinders with small diameters punchings, stamped pieces and machine –formed parts in power distribution and special transformers.

Calendared -Press Board TD12
Calendared -Press Board TD12 is only used in distribution transformers. Press Board TD12 was developed for the production of punched and embossed parts for distribution transformers .The development and in-line installation of a highly sensitive metal detector guarantees board free from metallic particles.

Pre compressed /Hot-Press Dried-Transformer board T IV
Applications of transformer boards T IV are strips, cylinders, spacers, plates, washers and supports. Transformer board T IV not only exhibits the highest mechanical and electrical strength but also offers dimensional stability and low shrinkage.
