Overview
SIST EN 60371-3-7:1998/A1:2007 specifies requirements for polyester film mica paper with an epoxy resin binder, designed for single conductor taping in electrical insulation applications. Developed by the Slovenian Institute for Standardization (SIST) and aligned with IEC and EN standards, this document outlines the essential properties, performance factors, and quality measures for mica-based insulating materials with added polyester film reinforcement.
This updated amendment ensures harmonization with international testing methods and references, providing a comprehensive and up-to-date resource for manufacturers, users, and specifiers of electrical insulation materials.
Key Topics
- Material Composition: Defines the structure of the composite - mica paper bonded with epoxy resin onto a PET (polyethylene terephthalate) polyester backing film.
- Product Designation: Outlines a standardized designation (type number) for easier specification and ordering.
- Performance Requirements: Details essential characteristics, including thickness, stiffness, electrical strength, and tensile strength.
- Electric strength: Minimum 50 kV/mm
- Tensile strength: Minimum 25 N/10 mm width (23 µm film), 40 N/10 mm width (30 µm film)
- Test Methods: Refers to internationally recognized test protocols for verifying technical properties (IEC 60371-2 for thickness, stiffness, tensile strength; IEC 60243-1 for electrical strength).
- Safety and Compliance: Highlights user responsibility for safe handling of materials and adherence to up-to-date referenced standards.
Applications
Polyester film mica paper with an epoxy resin binder is widely used for:
- Insulation of Single Conductors: Ideal for wrapping and taping individual electrical conductors to enhance dielectric strength and mechanical protection.
- High-Voltage Equipment: Suited for applications in transformers, electric motors, generators, and other devices requiring robust electrical insulation.
- Electrical and Electronic Industry: Used wherever reliable insulation and heat resistance are critical, particularly in demanding industrial environments.
- Repairs and Upgrades: Facilitates maintenance and retrofitting for enhanced electrical safety in legacy equipment.
The use of polyester film-backed mica paper ensures improved mechanical stability and resistance to thermal and electrical stresses, prolonging the operational lifespan of electrical components.
Related Standards
To ensure comprehensive compliance and understanding, the following referenced standards are essential:
- IEC 60243-1: Electrical strength of insulating materials - Test methods at power frequencies.
- IEC 60371-2: Specification for insulating materials based on mica - Methods of test.
- IEC 60371-3-2: Mica paper products for insulation - Specifications for individual materials.
- IEC 60674-3-2: Specification for plastic films for electrical purposes, specifically oriented PET films.
These standards provide essential test methods and further specifications for mica-based insulation and the materials used in their fabrication.
By applying SIST EN 60371-3-7:1998/A1:2007, manufacturers, engineers, and quality assurance professionals can ensure that mica-based insulating materials for single conductor taping meet international safety, performance, and reliability requirements. This guarantees optimal insulation performance and longer equipment life in a wide range of electrical applications.
