JB/10442 "Electrical diamond coated insulating paper" is divided into three parts: - Part 1: Definition and general requirements:
- Part 2: Test methods:
- Part 3: Single material diamond epoxy adhesive insulating paper. This part is the third part of JB Hall 10442. This part is formulated for the first time.
This part is proposed by the China Machinery Industry Federation. This part is under the jurisdiction of the National Technical Committee for Standardization of Insulating Materials. This part was drafted by Guilin Electric Science Research Institute, Nantong Hongan Sanmu Insulation Material Co., Ltd., Leshan Ouda Insulation Material Co., Ltd., and Shenyang Transformer Co., Ltd. The main drafters of this part are Li Bingsong, Jian Xuemei, Chen Kuan, Yang Heping, Lei Qiang, and Xiao Fuming. 1 Scope
Electrical diamond coated insulating paper
Part 3: Single material
Diamond epoxy adhesive insulating paper
JB/T10442.3--2004
This part of JB/T10442 specifies the product code, performance requirements, inspection rules, test methods, packaging, marking, transportation and storage of diamond epoxy adhesive insulating paper for electrical use.
This part is used for diamond epoxy adhesive insulating paper. The product is made by coating the modified epoxy resin on the insulating paper in a diamond shape and curing it into the B stage. It can be used for turn-to-turn and inter-layer insulation of transformers and mutual inductors. 2 Normative references
