EN 61061-3-1:1998

Overview

EN 61061-3-1:1998 is a European standard developed by the CLC (European Committee for Electrotechnical Standardization) that specifies requirements for non-impregnated densified laminated wood sheets produced from beech veneer, intended for electrical purposes. As part of the EN 61061 series, this document establishes specific criteria for the selection and use of beech veneer sheets, ensuring consistent quality and reliable performance in electrical insulation applications.

Non-impregnated densified laminated wood, particularly from beech veneer, is widely used as an insulating material in varied electrical equipment due to its favorable mechanical and dielectric properties. This standard outlines the properties, identification, and requirements for sheets manufactured according to EN 61061-1.

Key Topics

• Material Specifications: Details the specific requirements for physical and mechanical properties of beech veneer sheets, including density, moisture content, and appearance standards.
• Quality Assurance: Describes the criteria for acceptance, including parameters of lamination, permitted defects, and uniformity of the finished product.
• Testing and Compliance: References procedures for verifying conformity with the standard, such as dimensional checks and performance assessments.
• Marking and Documentation: Identifies necessary markings, labelling, and certification information for traceability and compliance within manufacturing and supply processes.

Applications

The main applications for non-impregnated densified laminated wood sheets made from beech veneer include:

• Electrical Insulation: Used in switchgear, transformer windings, and electrical machinery as barrier or structural insulation where mechanical strength and dielectric performance are vital.
• Component Manufacturing: Suitable for fabricating insulating supports, spacers, and frameworks within electrical devices.
• Replacement Material: Serves as a sustainable alternative to other insulating materials in environments where oil and resin impregnation are unnecessary.

The consistent characteristics defined by EN 61061-3-1 ensure these sheets are dependable and fit for purpose, facilitating their broader use in electrical manufacturing and maintenance.
