Lignostone® Transformerwood® - for transformers
Under the brand name Lignostone® Transformerwood® we offer you a laminated densified wood according to IEC 61061 for the construction of transformers that consists of beech veneers (Fagus sylvatica), which are joined together with thermosetting synthetic resins under pressure and heat. Lignostone® Transformerwood® has the following properties:
- good electrical insulation
- very good oil absorption
- low specific weight
- withstands high mechanical loading
- low- and high-temperature resistance
- resistance to abrasion and wear

Grades
- Lignostone® L I/2 E3
- Lignostone® M I/2 E3
- Lignostone® L II/2 E3
- Lignostone® M II/2 E3
- Lignostone® L X/2 E3
- Lignostone® M X/2 E3
Veneer quality
- SQ = Standard quality - Fulfills the requirements of IEC 61061
- HQ = High Quality - Surpasses the requirements of IEC 61061
- TQ = Top Quality - Surpasses by far the requirements of IEC 61061
Key to identification
The required grade for a specific application is defined by
Densification symbols
L = 0.75 to 1.05 g/cm³
M = 1.10 to 1.25 g/cm³
H = 1.30 to 1.40 g/cm³
Lamination
I= parallel
II= crosswise
X= tangential
Veneer thickness
1 = veneers < 2 mm
2 = veneers ≥ 2 mm
Type of resin
without character = mechanical types
E3 = electrical types
Example: An example for identification of one of the standard types: LII/2-E3 = Low density – crosswise lamination – with ≥ 2.0 mm veneer – electrical type. We also supply special types for applications with particular requirements.
