GB/T 19264.1-2011

Manufacturers of electrical equipment and suppliers of insulating materials use this standard to define and classify pressboard and presspaper, ensuring the materials meet basic requirements for electrical insulation. It provides a unified basis for material selection and acceptance, which is crucial for the reliability and safety of electrical devices.

电气设备制造商和绝缘材料供应商使用该标准来定义和分类压纸板和薄纸板，确保材料满足电气绝缘的基本要求。该标准为材料的选择和验收提供了统一依据，对保证电气设备的可靠性和安全性至关重要。

This standard specifies definitions, classification, and general requirements for pressboard and presspaper used in electrical insulation. Materials must be made entirely from vegetable fibers, free from impurities and bonding agents, with optional coloring. It classifies numerous types based on fiber composition and properties like chemical purity, density, and oil absorbency, providing application examples. Requirements for thickness, machinability (shearing, punching), and packaging are also included.

该标准规定了电气用压纸板和薄纸板的定义、分类和一般要求，适用于电气绝缘领域。材料必须由纯植物纤维制成，无杂质和粘合剂，并可按需添加着色剂。标准详细列出了多种类型，基于纤维成分和性能（如化学纯度、密度、吸油性）进行分类，并给出了应用实例。对厚度、机械加工性能（剪切、冲孔）和包装运输也提出了要求。
