The application areas of Laminated Pressboard include press rings, end rings, shield rings, beams, support strips, and fixing parts for power, distribution, and special transformers. Laminated Pressboards are usually processed into components that provide mechanical support for windings, lead exits, and lead ends.
Laminated Pressboards are produced from boards with various thicknesses, and their densities range between 1.20 and 1.25 g/cm³. These boards are classified as a class (105°C) insulation material and have a pure cellulose colour.
There are two types of Laminated Pressboards available:
ELBC utilizes a water-based casein glue with excellent transformer oil permeability, while ELBP boasts the highest mechanical strength and uses a polyester glue resin. Boards are bonded together using a robust pressing method, and we recommend using polyester glue for thicknesses exceeding 40 mm.
Our machines can work on large-dimension insulation components in various geometries, such as clamping rings for large power transformers and yoke clamping parts for traction transformer cores. The working space dimensions are 3200x3200x700 mm, with a handling precision of +/- 0.2 mm and a positioning precision of +/- 0.030 mm.
