Foreword

This guidance document refers to IEC 60893-3-2.2003 "Industrial materials thermosetting resin industrial hard laminates for electrical insulation" Part 3. Requirements for single-material specifications for hard epoxy laminates (English version). This guidance technical document was proposed by the China Electrical Equipment Industry Association. This guidance document is under the jurisdiction of the National Technical Committee for Standardization of Insulation Materials (SAC/TC51). This guiding technical document was drafted by: Oriental Insulation Materials Co., Ltd. The main drafters of this guiding technical document. Liu Feng, Zhao Ping. This guidance document is for the first time. GB /Z21213-2007 Halogen-free flame retardant high-strength glass cloth laminate

1 Scope

This guiding technical document specifies the requirements, the test methods, the inspection rules and the provisions on marking, packaging, transport and storage for halogen-free flame-retardant high-strength glass cloth laminated sheets. This guiding technical document applies to halogen-free flame-retardant high-strength glass cloth laminated sheets made by hot pressing, using alkali-free glass cloth treated with a coupling agent as the reinforcing material and impregnated with a halogen-free flame-retardant resin of temperature index 155. Halogen-free flame-retardant high-strength glass cloth laminated sheets have a high retention of mechanical strength in the hot state; they suit motors and electrical equipment of temperature index 155, are used as insulating structural parts, and can be used in a damp environment and in transformer oil.

This guidance technical document specifies the requirements, test methods, inspection rules, signs, packaging, and halogen-free flame-retardant high-strength glass cloth laminates. Transportation and storage. This guidance document applies to non-alkali glass cloth treated with a coupling agent as a reinforcing material, immersed in a halogen-free resistance with a temperature index of 155. A resin-free, halogen-free, flame-retardant, high-strength glass cloth laminate. Halogen-free flame-retardant high-strength glass cloth laminate with high thermal mechanical strength retention rate, suitable for motors and electrical appliances with a temperature index of 155 The device is used as an insulating structural component and can be used in wet environments and transformer oils.
