IEC 60819-3-1:2001

Overview

IEC 60819-3-1:2001 is an international standard published by the International Electrotechnical Commission (IEC). This standard provides specific requirements for filled glass paper, a type of non-cellulosic paper used in electrical insulation applications. IEC 60819-3-1:2001 details two grades of filled glass paper:

• P-FG type 1: High inorganic content, maximum organic content of 15%
• P-FG type 2: Medium inorganic content, maximum organic content of 25%

Filled glass papers are engineered to provide reliable dielectric and mechanical performance in electrical apparatus, supporting the safety and longevity of electrical insulation systems.

Key Topics

The standard addresses the following primary aspects:

• Material Classification: Criteria differentiating type 1 and type 2 filled glass papers, based on inorganic and organic content.
• Physical and Electrical Properties: Requirements for thickness, grammage, moisture content, tensile strength, dielectric strength, and elongation at break.
• Thermal Classification: Filled glass papers must maintain a relative temperature index of up to 220°C, ensuring suitability for high-temperature electrical environments.
• Testing Methods: Reference to IEC 60819-2 for the standardized test procedures that verify compliance with the specified properties.
• Quality Compliance: Adherence to both the general requirements of IEC 60819-1 and the unique specifications outlined for filled glass paper.

Applications

Filled glass paper specified by IEC 60819-3-1:2001 is widely used in electrical insulation systems due to its strong dielectric properties, thermal stability, and robust mechanical characteristics. Typical applications include:

• Transformer and Motor Insulation: Used in winding insulation, slot liners, and phase barriers.
• Capacitors: Applied as an insulating layer within capacitive assemblies.
• Switchgear and Control Equipment: Provides insulation for operational safety in high-voltage environments.
• Laminates and Composites: Incorporated as a base material for creating advanced insulating laminates in power electronics.
• Thermal Management Systems: Utilized in devices where insulation is required under high thermal loading.

By choosing filled glass paper compliant with IEC 60819-3-1, manufacturers and equipment specifiers can ensure consistent performance, durability, and safety in demanding electrical apparatus.
