TS EN 60763-1

TS EN 60763-1 is a terminology and framework standard for laminated pressboard, covering definitions, classification and general requirements. In electrical insulation, laminated pressboard is a rigid insulating material built up from multiple pressed layers, combining mechanical strength with dielectric performance; this standard organises how that product family is named and broadly categorised.

Where laminated pressboard fits in electrical insulation

Pressboard is typically a cellulose-based insulating board formed by compacting layers under high pressure. It is used in power transformers and similar electrical equipment for winding supports, spacer parts and structural insulation components. For materials like this, precise terminology matters because thickness, density, layer structure and intended use all influence electrical and mechanical behaviour.

What this part provides as a common technical frame

• Standardises core terminology.
• Supports classification of laminated pressboard types.
• Provides a shared baseline for general requirements.
• Helps keep production, procurement and technical communication consistent across the same product family.

This listing refers to a withdrawn edition of the standard, so it should be treated as a historical reference in current practice. Technically, however, it remains useful for understanding how pressed cellulose-based boards are named and grouped within the wider field of electrical insulating materials.
