This standard is a revision of JB5913-91< electrostatic precipitator cathode wire. When this standard was revised, spiral, V, line and V were added. At the same time, the shape tolerance "straightness" specified in the original standard was changed to the shape deviation "curvature" according to the characteristics of easy deformation of flexible profiled parts, making the definition and measurement method of shape deviation more reasonable. practical.
This standard will replace JB5913--91 from the effective date. This standard was proposed and coordinated by the Electrostatic Precipitator Sub-Technical Committee of the Environmental Protection Machinery Standardization Technical Committee of the Ministry of Machinery. This standard was drafted by: Kunshan Chengbei Electric Precipitator Equipment Factory. The main drafters of this standard are: Li Yucheng, Yang Mianshou, Sheng Wanrui, Chen Kangyuan, and Zhu Huafu.
