Foreword

GB/T 15022 "electrically insulating resin-based active composite" is divided into the following sections.

--- Part 1. Definition and general requirements;

--- Part 2. Test methods;

--- Part 3. No filler epoxy resin compound;

--- Part 4. Unsaturated polyester-based impregnating resin;

--- Part 5. Quartz filler epoxy resin composite;

--- Part 6. Nuclear Power Plant 1E level distribution transformer insulation with epoxy resin;

This section GB/T 15022 Part 2.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This Part Replaces GB/T 15022.2-2007 "Electrical insulating resin-based active compounds Part 2. Test methods." This section Compared with GB/T 15022.2-2007 compared to the main technical changes are as follows.

--- The "normative references" in the ISO , IEC standards to the corresponding national standards, and an increase of GB/T 21298-2007 and other national standards (see Chapter 2, 2007 edition Chapter 2);

--- The sample preparation and sample preparation should be changed to the relevant national standards (see Chapter 3, 2007 edition Chapter 3);

--- In the "test method of resin-based active compounds before curing" added the "appearance" pilot project, delete the "softening temperature", "chlorine Content "two pilot projects (see Chapter 4, Chapter 4 of the 2007 edition);

--- In the "cured resin-based active composite test method" adds "thermal conductivity", "linear expansion coefficient" and "temperature change test Experience "three pilot projects (see Chapter 5, 2007 edition of Chapter 5).

This section uses the redrafted law reference IEC 60455-2:2015 "electrically insulating resin-based active compound Part 2. Test side Law ", the degree of consistency with IEC 60455-2:2015 is not equivalent.

This part is proposed by China Electrical Equipment Industry Association.

This part of the National Standardization Technical Committee insulation materials (SAC/TC51) centralized.
