Introduction

The standard of resin-based active compound for electrical insulation is widely used in the research and development, production, quality inspection, sales, acceptance and technical delivery of this series of products.

flow etc. This document can guide the industry to carry out the detection and quality assessment of resin-based active compounds for electrical insulation, and can improve the quality of such products.

quality and application reliability.

There are currently nine main types of resin-based active compounds for electrical insulation, corresponding to IEC 60455 (resins for electrical insulation).

The standard is divided into different parts (or articles), in order to maintain the basic consistency with the corresponding IEC standard preparation method, in addition

The technical performance requirements for different types of resin products are also different. When compiling this product standard, it is necessary to list different parts separately.

GB/T 15022 specifies the definition and general requirements, test methods, individual material products of resin-based reactive compounds for electrical insulation

The standard consists of the following parts.

--- Part 1.Definitions and general requirements. The purpose is to determine the nomenclature, definition, classification and

General requirements.

--- Part 2.Test methods. The purpose is to determine a test method for resin-based reactive composites for electrical insulation.

--- Part 3.Unfilled epoxy resin composites. The purpose was to determine the post-curing requirements for unfilled epoxy resin compounds.

--- Part 4.Impregnating resin based on unsaturated polyester. The purpose is to identify general requirements for unsaturated polyester based impregnating resins.

--- Part 5.Quartz filler epoxy resin composites. The purpose was to determine the post-curing requirements of the epoxy resin compound of the quartz filler.

--- Part 6.Epoxy casting resin for insulation of Class 1E distribution transformers in nuclear power plants. The purpose is to determine the level 1E distribution transformer of nuclear power plant

Requirements, test methods, inspection rules, and packaging, marking, storage and transportation of epoxy resin for device insulation.

--- Part 7.Epoxy anhydride vacuum pressure impregnation (VPI) resin. The objective was to identify epoxy anhydride vacuum pressure impregnation (VPI) resins

requirements, test methods, inspection rules and packaging, marking, storage and transportation.

--- Part 8.Epoxy-modified unsaturated polyester vacuum pressure impregnation (VPI) resin. The purpose is to determine the epoxy modified unsaturated polyester

Classification, requirements, test methods, inspection rules and packaging, marking, storage and transportation of vacuum pressure impregnation (VPI) resins.

--- Part 9.Resin for cable accessories. The purpose is to determine the terms and definitions, nomenclature, type tests, tests of resins for cable accessories
